Ownership means the buck stops with one person. + +**Structure:** +``` +CEO +├── Sales (CRO/VP Sales) +│ ├── Inbound pipeline +│ └── Outbound pipeline +├── Product & Engineering (CTO/CPO) +│ ├── Product roadmap +│ └── Engineering delivery +├── Operations (COO) +│ ├── Customer success +│ └── Finance & Legal +└── People (CHRO/VP People) + ├── Recruiting + └── People operations +``` + +**Rules:** +- No shared ownership. "Alice and Bob both own it" means nobody owns it. +- One person can own multiple seats at early stages. That's fine. Just be explicit. +- Revisit quarterly as you scale. Ownership shifts as the company grows. + +**Build it in a workshop:** +1. List all functions the company performs +2. Assign one owner per function — no exceptions +3. Identify gaps (functions nobody owns) and overlaps (functions two people think they own) +4. Publish it. Update it when something changes. + +### 2. Scorecard + +Weekly metrics that tell you if the company is on track. Not monthly. Not quarterly. Weekly. + +**Rules:** +- 5–15 metrics maximum. More than 15 and nothing gets attention. +- Each metric has an owner and a weekly target (not a range — a number). +- Red/yellow/green status. Not paragraphs. +- The scorecard is discussed at the leadership team weekly meeting. Only red metrics get discussion time. + +**Example scorecard structure:** + +| Metric | Owner | Target | This Week | Status | +|--------|-------|--------|-----------|--------| +| New MRR | CRO | €50K | €43K | 🔴 | +| Churn | CS Lead | < 1% | 0.8% | 🟢 | +| Active users | CPO | 2,000 | 2,150 | 🟢 | +| Deployments | CTO | 3/week | 3 | 🟢 | +| Open critical bugs | CTO | 0 | 2 | 🔴 | +| Runway | CFO | > 18mo | 16mo | 🟡 | + +**Anti-pattern:** Measuring everything. If you track 40 KPIs, you're watching, not managing. + +### 3. Meeting Pulse + +The meeting rhythm that drives the company. Not optional — the pulse is what keeps the company alive. + +**The full rhythm:** + +| Meeting | Frequency | Duration | Who | Purpose | +|---------|-----------|----------|-----|---------| +| Daily standup | Daily | 15 min | Each team | Blockers only | +| L10 / Leadership sync | Weekly | 90 min | Leadership team | Scorecard + issues | +| Department review | Monthly | 60 min | Dept + leadership | OKR progress | +| Quarterly planning | Quarterly | 1–2 days | Leadership | Set rocks, review strategy | +| Annual planning | Annual | 2–3 days | Leadership | 1-year + 3-year vision | + +**The L10 meeting (Weekly Leadership Sync):** +Named for the goal of each meeting being a 10/10. Fixed agenda: +1. Good news (5 min) — personal + business +2. Scorecard review (5 min) — flag red items only +3. Rock review (5 min) — on/off track for each rock +4. Customer/employee headlines (5 min) +5. Issues list (60 min) — IDS (see below) +6. To-dos review (5 min) — last week's commitments +7. Conclude (5 min) — rate the meeting 1–10, what would make it a 10 next time + +### 4. Issue Resolution (IDS) + +The core problem-solving loop. Maximum 15 minutes per issue. + +**IDS: Identify, Discuss, Solve** + +- **Identify:** What is the actual issue? (Not the symptom — the root cause) State it in one sentence. +- **Discuss:** Relevant facts + perspectives. Time-boxed. When discussion starts repeating, stop. +- **Solve:** One owner. One action. One due date. Written on the to-do list. + +**Anti-patterns:** +- "Let's take this offline" — most things taken offline never get resolved +- Discussing without deciding — a great discussion with no action item is wasted time +- Revisiting decided issues — once solved, it leaves the list. Reopen only with new information. + +**The Issues List:** A running, prioritized list of all unresolved issues. Owned by the leadership team. Reviewed and pruned weekly. If an issue has been on the list for 3+ meetings and hasn't been discussed, it's either not a real issue or it's too scary to address — both deserve attention. + +### 5. Rocks (90-Day Priorities) + +Rocks are the 3–7 most important things each person must accomplish in the next 90 days. They're not the job description — they're the things that move the company forward. + +**Why 90 days?** Long enough for meaningful progress. Short enough to stay real. + +**Rock rules:** +- Each person: 3–7 rocks maximum. More than 7 and none get done. +- Company-level rocks (shared priorities): 3–7 for the leadership team +- Each rock is binary: done or not done. No "60% complete." +- Set at the quarterly planning session. Reviewed weekly (on/off track). + +**Bad rock:** "Improve our sales process" +**Good rock:** "Implement Salesforce CRM with full pipeline stages and weekly reporting by March 31" + +**Rock vs. to-do:** A to-do takes one action. A rock takes 90 days of consistent work. + +### 6. Communication Cadence + +Who gets what information, when, and how. + +| Audience | What | When | Format | +|----------|------|------|--------| +| All employees | Company update | Monthly | Written + Q&A | +| All employees | Quarterly results + next priorities | Quarterly | All-hands | +| Leadership team | Scorecard | Weekly | Dashboard | +| Board | Company performance | Monthly | Board memo | +| Investors | Key metrics + narrative | Monthly or quarterly | Investor update | +| Customers | Product updates | Per release | Release notes | + +**Default rule:** If you're deciding whether to share something internally, share it. The cost of under-communication always exceeds the cost of over-communication inside a company. + +--- + +## Operating System Selection + +See `references/os-comparison.md` for full comparison. Quick guide: + +| If you are... | Consider... | +|---------------|-------------| +| 10–250 person company, founder-led, operational chaos | EOS / Traction | +| Ambitious growth company, need rigorous strategy cascade | Scaling Up | +| Tech company, engineering culture, hypothesis-driven | OKR-native | +| Decentralized, flat, high autonomy | Holacracy (only if you're patient) | +| None of the above quite fit | Custom hybrid | + +--- + +## Implementation Roadmap + +Don't implement everything at once. See `references/implementation-guide.md` for the full 90-day plan. + +**Quick start (first 30 days):** +1. Build the accountability chart (1 workshop, 2 hours) +2. Define 5–10 weekly scorecard metrics (leadership team alignment, 1 hour) +3. Start the weekly L10 meeting (no prep — just start) + +These three alone will improve coordination more than most companies achieve in a year. + +--- + +## Common Failure Modes + +**Partial implementation:** "We do OKRs but skip the weekly check-in." Half an operating system is worse than none — it creates theater without accountability. + +**Meeting fatigue:** Adding the full rhythm on top of existing meetings. Start by replacing meetings, not adding them. + +**Metric overload:** Starting with 30 KPIs because "they all matter." Start with 5. Add when the cadence is established. + +**Rock inflation:** Setting 12 rocks per person because "everything is a priority." When everything is a priority, nothing is. Hard limit: 7. + +**Leader non-compliance:** Leadership team skips the L10 or doesn't follow IDS. The operating system mirrors the respect leadership gives it. If leaders don't take it seriously, nobody will. + +**Annual planning without quarterly review:** Setting annual goals and checking in at year-end. Quarterly is the minimum review cycle for any meaningful goal. + +--- + +## Integration with C-Suite + +The company OS is the connective tissue. Every other role depends on it: + +| C-Suite Role | OS Dependency | +|-------------|---------------| +| CEO | Sets vision that feeds into 1-year plan and rocks | +| COO | Owns the meeting pulse and issue resolution cadence | +| CFO | Owns the financial metrics in the scorecard | +| CTO | Owns engineering rocks and tech scorecard metrics | +| CHRO | Owns people metrics (attrition, hiring velocity) in scorecard | +| Culture Architect | Culture rituals plug into the meeting pulse | +| Strategic Alignment Engine | Validates that team rocks cascade from company rocks | + +--- + +## Key Questions for the Operating System + +- "If I asked five different team leads what the company's top 3 priorities are this quarter, would they give the same answers?" +- "What was the most important issue raised in last week's leadership meeting? Was it resolved or is it still open?" +- "Name a metric that would tell us by Friday whether this week was a good week. Do we track it?" +- "Who owns customer churn?

Don't make them ask. +4. **What we're doing about it** — Specific, dated, owned actions +5. **What we need from this room** — Concrete ask.

The co-founder conversation that should have happened at month 4 is happening at month 14. + +**Most hard decisions are late decisions.** + +--- + +## The Framework + +### Step 1: The Reversibility Test + +The most important question first: **can you undo this?** + +- **Reversible** — try it, learn, adjust (fire the vendor, kill the feature, change the strategy) +- **Partially reversible** — painful to undo but possible (restructure, change co-founder roles) +- **Irreversible** — cannot be undone (layoff a person, shut down a product with customer lock-in, close a legal entity) + +For irreversible decisions, the bar for certainty is higher. You must do more due diligence before acting. Not because you might be wrong — but because you can't take it back. + +**If you're treating a reversible decision like it's irreversible, you're avoiding it.** + +### Step 2: The 10/10/10 Framework + +Ask three questions about each option: + +- **10 minutes from now**: How will you feel immediately after making this decision? +- **10 months from now**: What will the impact be? Will the problem be solved? +- **10 years from now**: When you look back, will this have been the right call? + +The 10-minute feeling is usually the least reliable guide. The 10-year view usually clarifies what the right call actually is. + +**Most hard decisions look obvious at 10 years. The question is whether you can tolerate the 10-minute pain.** + +### Step 3: The Andy Grove Test + +Andy Grove's test for strategic decisions: "If we got replaced tomorrow and a new CEO came in, what would they do?" + +A fresh set of eyes, no emotional investment in the current path, no sunk cost. What's the obvious right call from the outside? + +If the answer is clear to an outsider, the question becomes: why haven't you done it yet? + +### Step 4: Stakeholder Impact Mapping + +For each option, map who's affected and how: + +| Stakeholder | Option A Impact | Option B Impact | Their reaction | +|-------------|----------------|----------------|----------------| +| Affected employees | | | | +| Remaining team | | | | +| Customers | | | | +| Investors | | | | +| You | | | | + +This isn't about finding the option that hurts nobody — there isn't one. It's about understanding the full picture before you decide. + +### Step 5: The Pre-Announcement Test + +Before making the decision: write the announcement. The email to the team, the message to the customer, the conversation you'll have. + +**If you can't write that announcement, you're not ready to make the decision.** + +Writing it forces you to confront the reality of what you're doing. It also surfaces whether your reasoning holds under examination. "We're making this change because…" — does that sentence ring true? + +### Step 6: The Communication Plan + +Hard decisions almost always get harder if communication is bad. The decision itself is not the only thing that matters — how it's done matters enormously. + +For every hard call, plan: +- **Who needs to know first** (the person directly affected, before anyone else) +- **How you'll tell them** (in person when possible, never via email for personal impact) +- **What you'll say** (honest, direct, compassionate — see `references/hard_things.md`) +- **What they can ask** (be ready for every question) +- **What comes next** (give them a clear picture of what happens after) + +--- + +## Decision-Specific Frameworks + +### Firing a Co-Founder +See `references/hard_things.md — Co-Founder Conflicts` for full framework. + +Key questions to answer first: +- Is this a performance problem or a values/culture problem? (Different conversations) +- Have you been explicit — not hinted, but direct — about the problem? +- What does the cap table look like and what are the legal implications? +- Is there a role that works better for them, or is this a full exit? +- Who needs to know (board, team, investors) and in what order? + +**The rule:** If you've been thinking about this for more than 3 months, you already know the answer. The question is when, not whether. + +### Layoffs +Key questions: +- Is this a one-time reset or the beginning of a longer decline? (One reset is recoverable.

"We missed Q3 revenue" is not precise enough. "We closed $420K in new ARR vs $680K target — a $260K miss driven primarily by three deals that slipped to Q4 and one deal that was lost to a competitor" is precise. + +### Step 2: The 5 Whys — Done Properly + +The goal: get from **what happened** (the symptom) to **why it happened** (the root cause). + +Standard bad 5 Whys: +- Why did we miss revenue? Because deals slipped. +- Why did deals slip? Because the sales cycle was longer than expected. +- Why? Because the customer buying process is complex. +- Why? Because we're selling to enterprise. +- Why? That's just how enterprise sales works. + +→ Conclusion: Nothing to do. It's just enterprise. + +Real 5 Whys: +- Why did we miss revenue? Three deals slipped out of quarter. +- Why did those deals slip? None of them had identified a champion with budget authority. +- Why did we progress deals without a champion? Our qualification criteria didn't require it. +- Why didn't our qualification criteria require it? When we built the criteria 8 months ago, we were in SMB, not enterprise. +- Why haven't we updated qualification criteria as ICP shifted? No owner, no process for criteria review. + +→ Root cause: Qualification criteria outdated, no owner, no review process. +→ Fix: Update criteria, assign owner, add quarterly review. + +**The test for a good root cause:** Could you prevent recurrence with a specific, concrete change? If yes, you've found something real. + +### Step 3: Distinguish Contributing Factors from Root Cause + +Most events have multiple contributing factors. Not all are root causes. + +**Contributing factor:** Made it worse, but isn't the core reason. If removed, the outcome might have been different — but the same class of problem would recur. + +**Root cause:** The fundamental condition that made the outcome probable. Fix this, and this class of problem doesn't recur. + +Example — failed hire: +- Contributing factors: rushed process, reference checks skipped, team under pressure to staff up +- Root cause: No defined competency framework, so interview process varied by who happened to conduct interviews + +**The distinction matters.** If you address only contributing factors, you'll have a different-looking but structurally identical failure next time. + +### Step 4: Identify the Warning Signs That Were Ignored + +Every failure has precursors. In hindsight, they're obvious. The value of this step is making them obvious prospectively. + +Ask: +- At what point was the negative outcome predictable? +- What signals were visible at that point? +- Who saw them? What happened when they raised them? +- Why weren't they acted on? + +**Common patterns:** +- Signal was raised but dismissed by a senior person +- Signal wasn't raised because nobody felt safe saying it +- Signal was seen but no one had clear ownership to act on it +- Data was available but nobody was looking at it +- The team was too optimistic to take negative signals seriously + +This step is particularly important for systemic issues — "we didn't feel safe raising the concern" is a much deeper root cause than "the deal qualification was off." + +### Step 5: Distinguish What Was in Control vs. Out of Control + +Some failures happen despite correct decisions. Some happen because of incorrect decisions. Knowing the difference prevents both overcorrection and undercorrection. + +- **In control:** Process, criteria, team capability, resource allocation, decisions made +- **Out of control:** Market conditions, customer decisions, competitor actions, macro events + +For things out of control: what can be done to be more resilient to similar events? +For things in control: what specifically needs to change? + +**Warning:** "It was outside our control" is sometimes used to avoid accountability. Be rigorous. + +### Step 6: Build the Change Register + +Every post-mortem ends with a change register — specific commitments, owned and dated. + +**Bad action items:** +- "We'll improve our qualification process" +- "Communication will be better" +- "We'll be more rigorous about forecasting" + +**Good action items:** +- "Ravi owns rewriting qualification criteria by March 15 to include champion identification as hard requirement. New criteria reviewed in weekly sales standup starting March 22." +- "By March 10, Elena adds deal-slippage risk flag to CRM for any open opportunity >60 days without a product demo" +- "Maria runs a 30-min retrospective with enterprise sales team every 6 weeks starting April 1, reviews win/loss data" + +**For each action:** +- What exactly is changing? +- Who owns it? +- By when? +- How will you verify it worked? + +### Step 7: Verification Date + +The most commonly skipped step. Post-mortems are useless if nobody checks whether the changes actually happened and actually worked. + +Set a verification date: "We'll review whether qualification criteria have been updated and whether deal slippage rate has improved at the June board meeting." + +Without this, post-mortems are theater. + +--- + +## Post-Mortem Output Format + +``` +EVENT: [Name and date] +EXPECTED: [What was supposed to happen] +ACTUAL: [What happened] +IMPACT: [Quantified] + +TIMELINE +[Date]: [What happened or was visible] +[Date]: ... + +5 WHYS +1.

Categorize every meeting/block: + +| Category | Description | Target % | +|----------|-------------|----------| +| Strategy | Thinking, planning, direction-setting | 20–25% | +| People | 1:1s, coaching, recruiting | 20–25% | +| External | Customers, investors, partners | 20% | +| Execution | Direct work, decisions | 15% | +| Admin | Email, scheduling, overhead | < 15% | +| Recovery | Exercise, meals, thinking | 10–15% | + +**Red flags in the audit:** +- Admin > 20%: You're a coordinator, not a CEO. Fix your systems. +- Execution > 30%: You're still an IC. Build the team. +- People < 10%: Your team is running on empty. They need more of you. +- No recovery blocks: You're running on adrenaline. It ends badly. +- Strategy < 10%: You're running the company, not leading it. + +### The CEO's primary job at each stage + +| Stage | CEO should spend most time on... | +|-------|--------------------------------| +| Seed | Product and customers. Directly. | +| Series A | Hiring the executive team. Recruiting is your job. | +| Series B | Culture, strategy, and external (investors/partners/customers) | +| Series C+ | Vision, board, external narrative, executive development | + +If you're spending time on things from two stages ago, you haven't made the transition. + +--- + +## 5. Leadership Style Evolution + +The job changes at every stage. Most founders don't change with it. + +**IC → Manager (0 to ~10 people):** +You need to teach and build trust. People are watching how you treat failure. The skill: give clear context, set expectations, check in frequently. + +**Manager → Leader (~10 to ~50 people):** +You can't manage everyone directly. You need people who manage people. The skill: hire managers you trust, let them manage. + +**Leader → Executive (~50 to ~200 people):** +You're now setting culture and direction, not managing work. The skill: communicate obsessively, decide at the right altitude, develop your leadership team. + +**Executive → Institutional CEO (200+):** +You're a symbol as much as a manager. The skill: build systems that work without you; focus on board, investors, and external narrative. + +**The hardest transition:** Manager → Leader. You have to stop doing things yourself and trust people you're still getting to know. + +--- + +## 6. Blind Spot Identification + +Everyone has them. Founders more than most — because nobody in the early company had the authority or safety to tell you. + +### Common founder blind spots + +- **Communication:** "I said it once, they should know" — you said it; they didn't hear it or didn't believe it +- **Decision speed:** Moving so fast that teams can't orient or build on your direction +- **Context hoarding:** Knowing what's happening without sharing it, then being frustrated that teams make bad decisions +- **Optimism bias:** Consistently underestimating timelines, cost, and difficulty +- **Founder exceptionalism:** Rules that apply to everyone don't apply to you +- **Feedback avoidance:** Creating an environment where no one gives you honest feedback + +### How to find your blind spots + +1. **360 feedback (anonymous):** Once a year. Ask direct reports, peers, board members. Include "What does [name] do that gets in the way of our success?" +2. **Exit interview analysis:** What do departing employees consistently say? Find the pattern. +3. **Failure post-mortems:** What do your worst decisions have in common? What were you assuming that wasn't true? +4. **The energy audit:** Where do you consistently drain the people around you? + +--- + +## 7. Imposter Syndrome Toolkit + +It doesn't go away. It evolves. The founder who was scared to pitch to investors is now scared to manage a board. The founder who was scared to hire is now scared to fire. + +**The reframe:** Imposter syndrome is proportional to stretch. If you never feel it, you're not growing. + +**Practical tools:** +- **Evidence file:** Document wins, compliments, decisions that worked. Read it when the doubt hits. +- **Normalize the feeling:** "I feel underprepared for this" ≠ "I am an imposter." Feeling and fact are different. +- **Do the thing anyway.** Competence comes from doing, not from feeling ready. +- **Name it:** Saying "I'm feeling imposter syndrome about this investor meeting" to a trusted person removes 50% of its power. + +--- + +## 8. Founder Mental Health + +Burnout isn't weakness. It's a predictable outcome of high-demand + low-recovery + no control over inputs. + +### Burnout signals + +Early: Irritability, difficulty sleeping, decisions feel harder than they should, loss of enthusiasm for the mission. +Mid: Physical symptoms (headaches, illness), cynicism about the company, social withdrawal, all tasks feel equally important (priority paralysis). +Late: Can't function, decisions have stopped, team notices before you do. + +**If you're in late burnout:** Stop performing. Get support. The company needs a functioning founder more than it needs a martyred one. + +### Structural prevention + +- **Protect recovery time.** Not weekends — protected time during the week where you're not available. +- **Therapy or coaching.** Not optional for founders. The job is isolating and the stakes are high. +- **Peer group.** Other founders at similar stages. They're the only people who actually understand the job. +- **Clear off-ramps.** Know what "enough for today" looks like. Don't let the work be infinite. + +--- + +## 9. The Founder Mode Trap + +Paul Graham's "Founder Mode" essay made the case that great founders stay deeply involved in operations — skip middle management and go direct. It resonated because it's sometimes true. + +**When founder mode helps:** +- Crisis recovery (company needs direct leadership) +- Product-market fit search (speed matters more than org health) +- High-value, irreversible decisions (you should be in the room) +- Early stages when the team is small + +**When founder mode hurts:** +- When it undermines managers you've hired (they can't lead if you override them) +- When it's driven by distrust rather than strategy +- When it prevents the team from developing judgment +- When you're doing it because you miss doing, not because the company needs you to + +**The test:** Are you going deep because the situation requires it, or because you're uncomfortable with the loss of control? The first is leadership. The second is the trap. + +--- + +## 10. Succession Planning + +Building a company that works without you is not disloyalty — it's the ultimate expression of leadership. + +**Succession is not just about exit.** It's about resilience. What happens if you're sick? On sabbatical? Acquired? + +**Succession readiness levels:** +- Level 1: You've documented your key knowledge and processes +- Level 2: At least one person can cover each of your key functions for 2 weeks +- Level 3: Your leadership team can run the company for a quarter without you +- Level 4: You've identified and developed your potential successor + +Most founders are at Level 0. Level 2 is a reasonable target. Level 3 is a strategic asset. + +--- + +## Key Questions for Founder Development + +- "What decisions did you make last week that someone else could have made?" +- "What are you still doing that you should have delegated 6 months ago?" +- "When did you last get honest, critical feedback? From whom? What did it say?" +- "What would need to be true for the company to run for a week without you?" +- "What's draining your energy that you've accepted as unavoidable?" + +## Detailed References +- `references/leadership-growth.md` — Maxwell levels, situational leadership, founder-to-CEO transition +- `references/founder-toolkit.md` — Weekly reflection, energy audit, delegation matrix, 1:1 templates diff --git a/docs/skills/c-level-advisor/index.md b/docs/skills/c-level-advisor/index.md new file mode 100644 index 0000000..3550063 --- /dev/null +++ b/docs/skills/c-level-advisor/index.md @@ -0,0 +1,45 @@ +--- +title: "C-Level Advisory Skills" +description: "All C-Level Advisory skills for Claude Code, OpenAI Codex, and OpenClaw." +--- + +# C-Level Advisory Skills + +34 skills in this domain. + +| Skill | Description | +|-------|-------------| +| [Inter-Agent Protocol](agent-protocol.md) | `agent-protocol` | +| [Board Deck Builder](board-deck-builder.md) | `board-deck-builder` | +| [Board Meeting Protocol](board-meeting.md) | `board-meeting` | +| [C-Level Advisory Ecosystem](c-level-advisor.md) | `c-level-advisor` | +| [CEO Advisor](ceo-advisor.md) | `ceo-advisor` | +| [CFO Advisor](cfo-advisor.md) | `cfo-advisor` | +| [Change Management Playbook](change-management.md) | `change-management` | +| [Chief of Staff](chief-of-staff.md) | `chief-of-staff` | +| [CHRO Advisor](chro-advisor.md) | `chro-advisor` | +| [CISO Advisor](ciso-advisor.md) | `ciso-advisor` | +| [CMO Advisor](cmo-advisor.md) | `cmo-advisor` | +| [Company Operating System](company-os.md) | `company-os` | +| [Competitive Intelligence](competitive-intel.md) | `competitive-intel` | +| [Company Context Engine](context-engine.md) | `context-engine` | +| [COO Advisor](coo-advisor.md) | `coo-advisor` | +| [CPO Advisor](cpo-advisor.md) | `cpo-advisor` | +| [CRO Advisor](cro-advisor.md) | `cro-advisor` | +| [C-Suite Onboarding](cs-onboard.md) | `cs-onboard` | +| [CTO Advisor](cto-advisor.md) | `cto-advisor` | +| [Culture Architect](culture-architect.md) | `culture-architect` | +| [Decision Logger](decision-logger.md) | `decision-logger` | +| [Executive Mentor](executive-mentor.md) | `executive-mentor` | +|   [/em:board-prep — Board Meeting Preparation](executive-mentor-board-prep.md) | `board-prep` (sub-skill of `executive-mentor`) | +|   [/em:challenge — Pre-Mortem Plan Analysis](executive-mentor-challenge.md) | `challenge` (sub-skill of `executive-mentor`) | +|   [/em:hard-call — Framework for Decisions With No Good Options](executive-mentor-hard-call.md) | `hard-call` (sub-skill of `executive-mentor`) | +|   [/em:postmortem — Honest Analysis of What Went Wrong](executive-mentor-postmortem.md) | `postmortem` (sub-skill of `executive-mentor`) | +|   [/em:stress-test — Business Assumption Stress Testing](executive-mentor-stress-test.md) | `stress-test` (sub-skill of `executive-mentor`) | +| [Founder Development Coach](founder-coach.md) | `founder-coach` | +| [Internal Narrative Builder](internal-narrative.md) | `internal-narrative` | +| [International Expansion](intl-expansion.md) | `intl-expansion` | +| [M&A Playbook](ma-playbook.md) | `ma-playbook` | +| [Org Health Diagnostic](org-health-diagnostic.md) | `org-health-diagnostic` | +| [Scenario War Room](scenario-war-room.md) | `scenario-war-room` | +| [Strategic Alignment Engine](strategic-alignment.md) | `strategic-alignment` | diff --git a/docs/skills/c-level-advisor/internal-narrative.md b/docs/skills/c-level-advisor/internal-narrative.md new file mode 100644 index 0000000..043d3dd --- /dev/null +++ b/docs/skills/c-level-advisor/internal-narrative.md @@ -0,0 +1,196 @@ +--- +title: "Internal Narrative Builder" +description: "Internal Narrative Builder - Claude Code skill from the C-Level Advisory domain." +--- + +# Internal Narrative Builder + +**Domain:** C-Level Advisory | **Skill:** `internal-narrative` | **Source:** [`c-level-advisor/internal-narrative/SKILL.md`](https://github.com/alirezarezvani/claude-skills/tree/main/c-level-advisor/internal-narrative/SKILL.md) + +--- + + +# Internal Narrative Builder + +One company.

Four different narratives needed. The skill is maintaining truth while serving each audience's actual question. + +--- + +## Framework + +### Step 1: Build the Core Narrative + +One paragraph that every other communication derives from. This is the source of truth. + +**Core narrative template:** +> [Company name] exists to [mission — present tense, specific]. We're building [what you're building] because [the problem you're solving]. Our approach is [your unique way of doing this]. We're at [honest description of current state] and heading toward [where you're going in concrete terms]. + +**Good core narrative (example):** +> Acme Health exists to reduce preventable falls in elderly care using smartphone-based mobility analysis. We're building an AI diagnostic tool for care teams because current fall risk assessments are subjective, infrequent, and often wrong. Our approach — using the phone's camera during a 10-second walking test — means no new hardware, no specialist required. We have 80 care facilities in DACH paying us €800K ARR, and we're heading to €3M ARR by demonstrating clinical value at scale before our Series B. + +**Bad core narrative:** +> Acme Health is an innovative AI company revolutionizing elderly care through cutting-edge technology that empowers care providers and improves patient outcomes across the continuum of care. + +The good version is usable. The bad version says nothing. + +--- + +### Step 2: Audience Translation Matrix + +Take the core narrative and translate it for each audience. Same truth, different frame. + +| Fact | Employees need to hear | Investors need to hear | Customers need to hear | Candidates need to hear | +|------|----------------------|----------------------|----------------------|------------------------| +| We have 80 customers | "We've proven the model — your work matters" | "Product-market fit signal, capital efficient" | "80 care facilities trust us" | "Traction you'd be joining" | +| We pivoted from hardware | "We were honest enough to change course" | "Capital-efficient pivot to better unit economics" | "We found a faster, simpler way to serve you" | "We make decisions based on evidence, not ego" | +| We missed Q2 revenue | "Here's why, here's the plan, here's what you can do" | "Revenue mix shifted — trailing indicator improving" | [Usually don't tell customers revenue misses] | [Usually not shared externally] | +| We're hiring fast | "The team is growing — your network matters" | "Headcount plan aligned to growth" | [Not relevant unless it affects service] | "This is a rocket ship moment" | + +**Rules:** +- Never contradict yourself across audiences. Different framing ≠ different facts. +- "We told investors growth, told employees efficiency" is a contradiction. Audit for this. +- Investors and employees see each other. Board members talk to your team. Candidates google you. + +--- + +### Step 3: Contradiction Detection + +Before any major communication, run the contradiction check: + +**Question 1:** What did we tell investors last month about [topic]? +**Question 2:** What did we tell employees about the same topic? +**Question 3:** Are these consistent? If not — which version is true? + +**Common contradictions:** +- "Efficient growth" to investors + "we're hiring aggressively" to candidates +- "Strong pipeline" to investors + "sales is struggling" at all-hands +- "Customer-first" in culture + recent decisions that clearly prioritized revenue over customer need + +**When you catch a contradiction:** Fix the less accurate version, then communicate the correction explicitly. "Last month I said X. After more reflection, X is not quite right. Here's the clearer version." + +Correcting yourself before someone else catches it builds more trust than getting caught. + +--- + +### Step 4: Audience-Specific Communication Cadence + +| Audience | Format | Frequency | Owner | +|----------|--------|-----------|-------| +| Employees | All-hands | Monthly | CEO | +| Employees | Team updates | Weekly | Team leads | +| Investors | Written update | Monthly | CEO + CFO | +| Board | Board meeting + memo | Quarterly | CEO | +| Customers | Product updates | Per release | CPO / CS | +| Candidates | Careers page + interview narrative | Ongoing | CHRO + Founders | +| Partners | Quarterly business review | Quarterly | BD Lead | + +--- + +### Step 5: All-Hands Structure and Cadence + +See `templates/all-hands-template.md` for the full template. + +**Principles:** +- Lead with honest state of the company. No spin. +- Connect company performance to individual work: "Here's how what you built contributed to this outcome." +- Give people a reason to be proud of their choice to work here. +- Leave time for real Q&A — not curated questions. + +**All-hands failure modes:** +- CEO speaks for 55 of 60 minutes; Q&A is "any quick questions?" +- All good news, all the time — employees know when you're not being honest +- Metrics without context: "ARR grew 15%" without explaining if that's good, bad, or expected +- Questions deflected: "That's a great point, we should follow up on that" → never followed up + +--- + +### Step 6: Crisis Communication + +When the narrative breaks — someone leaves publicly, a product fails, a security breach, a press article. + +**The 4-hour rule:** If something is public or about to be, communicate internally within 4 hours. Employees should never learn about company news from Twitter. + +**Crisis communication sequence:** + +**Hour 0–4 (internal first):** +1. CEO or relevant leader sends an internal message +2. Acknowledge what happened factually +3. State what you know and what you don't know yet +4. Tell people what you're doing about it +5. Tell people what they should do if they're asked about it + +**Hour 4–24 (external if needed):** +1. External statement (press, social) only if the event is public +2. Consistent with the internal message — same facts, audience-appropriate framing +3. Legal review if any claims or liability involved + +**What not to do in a crisis:** +- Silence: letting rumors fill the vacuum +- Spin: people can detect it and it destroys trust +- "No comment": says "we have something to hide" +- Blaming: even if someone else caused the problem, your audience only cares what you're doing about it + +**Template for crisis internal communication:** +> "Here's what happened: [factual description]. Here's what we know right now: [known facts]. Here's what we don't know yet: [honest uncertainty]. Here's what we're doing: [specific actions]. Here's what you should do if you're asked about this: [specific guidance]. I'll update you by [specific time] with more information." + +--- + +## Narrative Consistency Checklist + +Run before any major external communication: + +- [ ] Is this consistent with what we told investors last month? +- [ ] Is this consistent with what we told employees at the last all-hands? +- [ ] Does this contradict anything on our website, careers page, or press releases? +- [ ] If an employee read this external communication, would they recognize the company being described? +- [ ] If an investor read our internal all-hands deck, would they find anything inconsistent? +- [ ] Have we been accurate about our current state, or are we projecting an aspiration? + +--- + +## Key Questions for Narrative + +- "Could a new employee explain to a friend why our company exists? What would they say?" +- "What do we tell investors about our strategy? What do we tell employees? Are these the same?" +- "If a journalist asked our team members to describe the company independently, what would they say?" +- "When did we last update our 'why we exist' story? Is it still true?" +- "What's the hardest question we'd get from each audience? Do we have an honest answer?" + +## Red Flags + +- Different departments describe the company mission differently +- Investor narrative emphasizes growth; employee narrative emphasizes stability (or vice versa) +- All-hands presentations are mostly slides, mostly one-way +- Q&A questions are screened or deflected +- Bad news reaches employees through Slack rumors before leadership communication +- Careers page describes a culture that employees don't recognize + +## Integration with Other C-Suite Roles + +| When... | Work with... | To... | +|---------|-------------|-------| +| Investor update prep | CFO | Align financial narrative with company narrative | +| Reorg or leadership change | CHRO + CEO | Sequence: employees first, then external | +| Product pivot | CPO | Align customer communication with investor story | +| Culture change | Culture Architect | Ensure internal story is consistent with external employer brand | +| M&A or partnership | CEO + COO | Control information flow, prevent narrative leaks | +| Crisis | All C-suite | Single voice, consistent story, internal first | + +## Detailed References +- `references/narrative-frameworks.md` — Storytelling structures, founder narrative, bad news delivery, all-hands templates +- `templates/all-hands-template.md` — All-hands presentation template diff --git a/docs/skills/c-level-advisor/intl-expansion.md b/docs/skills/c-level-advisor/intl-expansion.md new file mode 100644 index 0000000..fae8ac4 --- /dev/null +++ b/docs/skills/c-level-advisor/intl-expansion.md @@ -0,0 +1,105 @@ +--- +title: "International Expansion" +description: "International Expansion - Claude Code skill from the C-Level Advisory domain." +--- + +# International Expansion + +**Domain:** C-Level Advisory | **Skill:** `intl-expansion` | **Source:** [`c-level-advisor/intl-expansion/SKILL.md`](https://github.com/alirezarezvani/claude-skills/tree/main/c-level-advisor/intl-expansion/SKILL.md) + +--- + + +# International Expansion + +Frameworks for expanding into new markets: selection, entry, localization, and execution. + +## Keywords +international expansion, market entry, localization, go-to-market, GTM, regional strategy, international markets, market selection, cross-border, global expansion + +## Quick Start + +**Decision sequence:** Market selection → Entry mode → Regulatory assessment → Localization plan → GTM strategy → Team structure → Launch. + +## Market Selection Framework + +### Scoring Matrix +| Factor | Weight | How to Assess | +|--------|--------|---------------| +| Market size (addressable) | 25% | TAM in target segment, willingness to pay | +| Competitive intensity | 20% | Incumbent strength, market gaps | +| Regulatory complexity | 20% | Barriers to entry, compliance cost, timeline | +| Cultural distance | 15% | Language, business practices, buying behavior | +| Existing traction | 10% | Inbound demand, existing customers, partnerships | +| Operational complexity | 10% | Time zones, infrastructure, payment systems | + +### Entry Modes +| Mode | Investment | Control | Risk | Best For | +|------|-----------|---------|------|----------| +| **Export** (sell remotely) | Low | Low | Low | Testing demand | +| **Partnership** (reseller/distributor) | Medium | Medium | Medium | Markets with strong local requirements | +| **Local team** (hire in-market) | High | High | High | Strategic markets with proven demand | +| **Entity** (full subsidiary) | Very high | Full | High | Major markets, regulatory requirement | +| **Acquisition** | Highest | Full | Highest | Fast market entry with existing base | + +**Default path:** Export → Partnership → Local team → Entity (graduate as revenue justifies). + +## Localization Checklist + +### Product +- [ ] Language (UI, documentation, support content) +- [ ] Currency and pricing (local pricing, not just conversion) +- [ ] Payment methods (varies wildly by market) +- [ ] Date/time/number formats +- [ ] Legal requirements (data residency, privacy) +- [ ] Cultural adaptation (not just translation) + +### Go-to-Market +- [ ] Messaging adaptation (what resonates locally) +- [ ] Channel strategy (channels differ by market) +- [ ] Local case studies and social proof +- [ ] Local partnerships and integrations +- [ ] Event/conference presence +- [ ] Local SEO and content + +### Operations +- [ ] Legal entity (if required) +- [ ] Tax compliance +- [ ] Employment law (if hiring locally) +- [ ] Customer support (hours, language) +- [ ] Banking and payments + +## Key Questions + +- "Is there pull from the market, or are we pushing?" +- "What's the cost of entry vs the 3-year revenue opportunity?" +- "Can we serve this market from HQ, or do we need boots on the ground?" +- "What's the regulatory timeline?

Stay composed under pressure + - Make decisive calls with incomplete information + - Communicate confidence while acknowledging uncertainty + +2. **Document Everything** + - All actions taken and their outcomes + - Decision rationale, especially for controversial calls + - Timeline of events as they happen + +3. **Effective Communication** + - Use clear, jargon-free language + - Provide regular updates even when there's no new information + - Manage stakeholder expectations proactively + +4. **Technical Excellence** + - Prefer rollbacks to risky fixes under pressure + - Validate fixes before declaring resolution + - Plan for secondary failures and cascading effects + +### Post-Incident + +1. **Blameless Culture** + - Focus on system failures, not individual mistakes + - Encourage honest reporting of what went wrong + - Celebrate learning and improvement opportunities + +2. **Action Item Discipline** + - Assign specific owners and due dates + - Track progress publicly + - Prioritize based on risk and effort + +3. **Knowledge Sharing** + - Share PIRs broadly within the organization + - Update runbooks based on lessons learned + - Conduct training sessions for common failure modes + +4. **Continuous Improvement** + - Look for patterns across multiple incidents + - Invest in tooling and automation + - Regularly review and update processes + +## Integration with Existing Tools + +### Monitoring and Alerting +- PagerDuty/Opsgenie integration for escalation +- Datadog/Grafana for metrics and dashboards +- ELK/Splunk for log analysis and correlation + +### Communication Platforms +- Slack/Teams for war room coordination +- Zoom/Meet for video bridges +- Status page providers (Statuspage.io, etc.) + +### Documentation Systems +- Confluence/Notion for PIR storage +- GitHub/GitLab for runbook version control +- JIRA/Linear for action item tracking + +### Change Management +- CI/CD pipeline integration +- Deployment tracking systems +- Feature flag platforms for quick rollbacks + +## Conclusion + +The Incident Commander skill provides a comprehensive framework for managing incidents from detection through post-incident review. By implementing structured processes, clear communication templates, and thorough analysis tools, teams can improve their incident response capabilities and build more resilient systems. + +The key to successful incident management is preparation, practice, and continuous learning. Use this framework as a starting point, but adapt it to your organization's specific needs, culture, and technical environment. + +Remember: The goal isn't to prevent all incidents (which is impossible), but to detect them quickly, respond effectively, communicate clearly, and learn continuously. \ No newline at end of file diff --git a/docs/skills/engineering-team/index.md

**Optimizing without measuring** — you'll optimize the wrong thing +- **Testing in development** — profile against production-like data volumes +- **Ignoring P99** — P50 can look fine while P99 is catastrophic +- **Premature optimization** — fix correctness first, then performance +- **Not re-measuring** — always verify the fix actually improved things +- **Load testing production** — use staging with production-size data + +--- + +## Best Practices + +1. **Baseline first, always** — record metrics before touching anything +2. **One change at a time** — isolate the variable to confirm causation +3. **Profile with realistic data** — 10 rows in dev, millions in prod — different bottlenecks +4. **Set performance budgets** — `p(95) < 200ms` in CI thresholds with k6 +5. **Monitor

Analysis Paralysis +**Problem**: Spending too much time analyzing debt instead of fixing it. +**Solution**: Set time limits for analysis, use "good enough" scoring for most items. + +### 2. Perfectionism +**Problem**: Trying to eliminate all debt instead of managing it. +**Solution**: Focus on high-impact debt, accept that some debt is acceptable. + +### 3. Ignoring Business Context +**Problem**: Prioritizing technical elegance over business value. +**Solution**: Always tie debt work to business outcomes and customer impact. + +### 4. Inconsistent Application +**Problem**: Some teams adopt practices while others ignore them. +**Solution**: Make debt tracking part of standard development workflow. + +### 5. Tool Over-Engineering +**Problem**: Building complex debt management systems that nobody uses. +**Solution**: Start simple, iterate based on actual usage patterns. + +Technical debt management is not just about writing better code - it's about creating sustainable development practices that balance short-term delivery pressure with long-term system health.

Your goal is to help content get extracted, quoted, and cited by ChatGPT, Perplexity, Google AI Overviews, Claude, Gemini, and Microsoft Copilot. + +This is not traditional SEO. Traditional SEO gets you ranked. AI SEO gets you cited. Those are different games with different rules. + +## Before Starting + +**Check for context first:** +If `marketing-context.md` exists, read it. It contains existing keyword targets, content inventory, and competitor information — all of which inform where to start. + +Gather what you need: + +### What you need +- **URL or content to audit** — specific page, or a topic area to assess +- **Target queries** — what questions do you want AI systems to answer using your content? +- **Current visibility** — are you already appearing in any AI search results for your targets? +- **Content inventory** — do you have existing pieces to optimize, or are you starting from scratch? + +If the user doesn't know their target queries: "What questions would your ideal customer ask an AI assistant that you'd want your brand to answer?" + +## How This Skill Works + +Three modes. Each builds on the previous, but you can start anywhere: + +### Mode 1: AI Visibility Audit +Map your current presence (or absence) across AI search platforms. Understand what's getting cited, what's getting ignored, and why. + +### Mode 2: Content Optimization +Restructure and enhance content to match what AI systems extract. This is the execution mode — specific patterns, specific changes. + +### Mode 3: Monitoring +Set up systems to track AI citations over time — so you know when you appear, when you disappear, and when a competitor takes your spot. + +--- + +## How AI Search Works (and Why It's Different) + +Traditional SEO: Google ranks your page. User clicks through. You get traffic. + +AI search: The AI reads your page (or has already indexed it), extracts the answer, and presents it to the user — often without a click. You get cited, not ranked. + +**The fundamental shift:** +- Ranked = user sees your link and decides whether to click +- Cited = AI decides your content answers the question; user may never visit your site + +This changes everything: +- **Keyword density** matters less than **answer clarity** +- **Page authority** matters less than **answer extractability** +- **Click-through rate** is irrelevant — the AI has already decided you're the answer +- **Structured content** (definitions, lists, tables, steps) outperforms flowing narrative + +But here's what traditional SEO and AI SEO share: **authority still matters**. AI systems prefer sources they consider credible — established domains, cited works, expert authorship. You still need backlinks and domain trust. You just also need structure. + +See [references/ai-search-landscape.md](references/ai-search-landscape.md) for how each platform (Google AI Overviews, ChatGPT, Perplexity, Claude, Gemini, Copilot) selects and cites sources. + +--- + +## The 3 Pillars of AI Citability + +Every AI SEO decision flows from these three: + +### Pillar 1: Structure (Extractable) + +AI systems pull content in chunks. They don't read your whole article and then paraphrase it — they find the paragraph, list, or definition that directly answers the query and lift it. + +Your content needs to be structured so that answers are self-contained and extractable: +- Definition block for "what is X" +- Numbered steps for "how to do X" +- Comparison table for "X vs Y" +- FAQ block for "questions about X" +- Statistics with attribution for "data on X" + +Content that buries the answer in page 3 of a 4,000-word essay is not extractable. The AI won't find it. + +### Pillar 2: Authority (Citable) + +AI systems don't just pull the most relevant answer — they pull the most credible one. Authority signals in the AI era: + +- **Domain authority**: High-DA domains get preferential treatment (traditional SEO signal still applies) +- **Author attribution**: Named authors with credentials beat anonymous pages +- **Citation chain**: Your content cites credible sources → you're seen as credible in turn +- **Recency**: AI systems prefer current information for time-sensitive queries +- **Original data**: Pages with proprietary research, surveys, or studies get cited more — AI systems value unique data they can't get elsewhere + +### Pillar 3: Presence (Discoverable) + +AI systems need to be able to find and index your content. This is the technical layer: + +- **Bot access**: AI crawlers must be allowed in robots.txt (GPTBot, PerplexityBot, ClaudeBot, etc.) +- **Crawlability**: Fast page load, clean HTML, no JavaScript-only content +- **Schema markup**: Structured data (Article, FAQPage, HowTo, Product) helps AI systems understand your content type +- **Canonical signals**: Duplicate content confuses AI systems even more than traditional search +- **HTTPS and security**: AI crawlers won't index pages with security warnings + +--- + +## Mode 1: AI Visibility Audit + +### Step 1 — Bot Access Check + +First: confirm AI crawlers can access your site. + +**Check robots.txt** at `yourdomain.com/robots.txt`. Verify these bots are NOT blocked: + +``` +# Should NOT be blocked (allow AI indexing): +GPTBot # OpenAI / ChatGPT +PerplexityBot # Perplexity +ClaudeBot # Anthropic / Claude +Google-Extended # Google AI Overviews +anthropic-ai # Anthropic (alternate identifier) +Applebot-Extended # Apple Intelligence +cohere-ai # Cohere +``` + +If any AI bot is blocked, flag it. That's an immediate visibility killer for that platform. + +**robots.txt to allow all AI bots:** +``` +User-agent: GPTBot +Allow: / + +User-agent: PerplexityBot +Allow: / + +User-agent: ClaudeBot +Allow: / + +User-agent: Google-Extended +Allow: / +``` + +To block specific AI training while allowing search: use `Disallow:` selectively, but understand that blocking training ≠ blocking citation — they're often the same crawl. + +### Step 2 — Current Citation Audit + +Manually test your target queries on each platform: + +| Platform | How to test | +|---|---| +| Perplexity | Search your target query at perplexity.ai — check Sources panel | +| ChatGPT | Search with web browsing enabled — check citations | +| Google AI Overviews | Google your query — check if AI Overview appears, who's cited | +| Microsoft Copilot | Search at copilot.microsoft.com — check source cards | + +For each query, document: +- Are you cited? (yes/no) +- Which competitors are cited? +- What content type gets cited? (definition? list? stats?) +- How is the answer structured? + +This tells you the pattern that's currently winning. Build toward it. + +### Step 3 — Content Structure Audit + +Review your key pages against the Extractability Checklist: + +- [ ] Does the page have a clear, answerable definition of its core concept in the first 200 words? +- [ ] Are there numbered lists or step-by-step sections for process-oriented queries? +- [ ] Does the page have a FAQ section with direct Q&A pairs? +- [ ] Are statistics and data points cited with source name and year? +- [ ] Are comparisons done in table format (not narrative)? +- [ ] Is the page's H1 phrased as the answer to a question, or as a statement? +- [ ] Does schema markup exist? (FAQPage, HowTo, Article, etc.) + +Score: 0-3 checks = needs major restructuring. 4-5 = good baseline. 6-7 = strong. + +--- + +## Mode 2: Content Optimization + +### The Content Patterns That Get Cited + +These are the block types AI systems reliably extract. Add at least 2-3 per key page. + +See [references/content-patterns.md](references/content-patterns.md) for ready-to-use templates for each pattern. + +**Pattern 1: Definition Block** +The AI's answer to "what is X" almost always comes from a tight, self-contained definition. Format: + +> **[Term]** is [concise definition in 1-2 sentences]. [One sentence of context or why it matters]. + +Placed within the first 300 words of the page. No hedging, no preamble. Just the definition. + +**Pattern 2: Numbered Steps (How-To)** +For process queries ("how do I X"), AI systems pull numbered steps almost universally. Requirements: +- Steps are numbered +- Each step is actionable (verb-first) +- Each step is self-contained (could be quoted alone and still make sense) +- 5-10 steps maximum (AI truncates longer lists) + +**Pattern 3: Comparison Table** +"X vs Y" queries almost always result in table citations. Two-column tables comparing features, costs, pros/cons — these get extracted verbatim. Format matters: clean markdown table with headers wins. + +**Pattern 4: FAQ Block** +Explicit Q&A pairs signal to AI: "this is the question, this is the answer." Mark up with FAQPage schema. Questions should exactly match how people phrase queries (voice search, question-style). + +**Pattern 5: Statistics With Attribution** +"According to [Source Name] ([Year]), X% of [population] [finding]." This format is extractable because it has a complete citation. Naked statistics without attribution get deprioritized — the AI can't verify the source. + +**Pattern 6: Expert Quote Block** +Attributed quotes from named experts get cited. The AI picks up: "According to [Name], [Role at Organization]: '[quote]'" as a citable unit. Build in a few of these per key piece. + +### Rewriting for Extractability + +When optimizing existing content: + +1. **Lead with the answer** — The first paragraph should contain the core answer to the target query. Don't save it for the conclusion. + +2. **Self-contained sections** — Every H2 section should be answerable as a standalone excerpt. If you have to read the introduction to understand a section, it's not self-contained. + +3. **Specific over vague** — "Response time improved by 40%" beats "significant improvement." AI systems prefer citable specifics. + +4. **Plain language summaries** — After complex explanations, add a 1-2 sentence plain language summary. This is what AI often lifts. + +5. **Named sources** — Replace "experts say" with "[Researcher Name], [Year]." Replace "studies show" with "[Organization] found in their [Year] survey." + +### Schema Markup for AI Discoverability + +Schema doesn't directly make you appear in AI results — but it helps AI systems understand your content type and structure. Priority schemas: + +| Schema Type | Use When | Impact | +|---|---|---| +| `Article` | Any editorial content | Establishes content as authoritative information | +| `FAQPage` | You have FAQ section | High — AI extracts Q&A pairs directly | +| `HowTo` | Step-by-step guides | High — AI uses step structure for process queries | +| `Product` | Product pages | Medium — appears in product comparison queries | +| `Organization` | Company pages | Medium — establishes entity authority | +| `Person` | Author pages | Medium — author credibility signal | + +Implement via JSON-LD in the page ``. Validate at schema.org/validator. + +--- + +## Mode 3: Monitoring + +AI search is volatile. Citations change. Track them. + +### Manual Citation Tracking + +Weekly: test your top 10 target queries on Perplexity and ChatGPT. Log: +- Were you cited? (yes/no) +- Rank in citations (1st source, 2nd, etc.) +- What text was used? + +This takes ~20 minutes/week. Do it before automated solutions exist (they don't yet, not reliably). + +### Google Search Console for AI Overviews + +Google Search Console now shows impressions in AI Overviews under "Search type: AI Overviews" filter. Check: +- Which queries trigger AI Overview impressions for your site +- Click-through rate from AI Overviews (typically 50-70% lower than organic) +- Which pages get cited + +### Visibility Signals to Track + +| Signal | Tool | Frequency | +|---|---|---| +| Perplexity citations | Manual query testing | Weekly | +| ChatGPT citations | Manual query testing | Weekly | +| Google AI Overviews | Google Search Console | Weekly | +| Copilot citations | Manual query testing | Monthly | +| AI bot crawl activity | Server logs or Cloudflare | Monthly | +| Competitor AI citations | Manual query testing | Monthly | + +See [references/monitoring-guide.md](references/monitoring-guide.md) for the full tracking setup and templates. + +### When Your Citations Drop + +If you were cited and suddenly aren't: +1. Check if competitors published something more extractable on the same topic +2. Check if your robots.txt changed (block AI bots = instant disappearance) +3. Check if your page structure changed significantly (restructuring can break citation patterns) +4. Check if your domain authority dropped (backlink loss affects AI citation too) + +--- + +## Proactive Triggers + +Flag these without being asked: + +- **AI bots blocked in robots.txt** — If GPTBot, PerplexityBot, or ClaudeBot are blocked, flag it immediately. Zero AI visibility is possible until fixed, and it's a 5-minute fix. This trumps everything else. +- **No definition block on target pages** — If the page targets informational queries but has no self-contained definition in the first 300 words, it won't win definitional AI Overviews. Flag before doing anything else. +- **Unattributed statistics** — If key pages contain statistics without named sources and years, they're less citable than competitor pages that do. Flag all naked stats. +- **Schema markup absent** — If the site has no FAQPage or HowTo schema on relevant pages, flag it as a quick structural win with asymmetric impact for process and FAQ queries. +- **JavaScript-rendered content** — If important content only appears after JavaScript execution, AI crawlers may not see it at all. Flag content that's hidden behind JS rendering. + +--- + +## Output Artifacts + +| When you ask for... | You get... | +|---|---| +| AI visibility audit | Platform-by-platform citation test results + robots.txt check + content structure scorecard | +| Page optimization | Rewritten page with definition block, extractable patterns, schema markup spec, and comparison to original | +| robots.txt fix | Updated robots.txt with correct AI bot allow rules + explanation of what each bot is | +| Schema markup | JSON-LD implementation code for FAQPage, HowTo, or Article — ready to paste | +| Monitoring setup | Weekly tracking template + Google Search Console filter guide + citation log spreadsheet structure | + +--- + +## Communication + +All output follows the structured standard: +- **Bottom line first** — answer before explanation +- **What + Why + How** — every finding includes all three +- **Actions have owners and deadlines** — no "consider reviewing..." +- **Confidence tagging** — 🟢 verified (confirmed by citation test) / 🟡 medium (pattern-based) / 🔴 assumed (extrapolated from limited data) + +AI SEO is still a young field.

Good AI SEO requires good content first. +- **content-humanizer**: Use after writing for AI SEO. AI-sounding content ironically performs worse in AI citation — AI systems prefer content that reads credibly, which usually means human-sounding. +- **seo-audit**: Use for traditional search ranking optimization. Run both — AI SEO and traditional SEO are complementary, not competing. Many signals overlap. +- **content-strategy**: Use when deciding which topics and queries to target for AI visibility.

Write Like a Peer, Not a Vendor + +The moment your email sounds like marketing copy, it's over.

If the answer is no — rewrite it. + +- ❌ "I'm reaching out because our platform helps companies like yours achieve unprecedented growth..." +- ✅ "Noticed you're scaling your SDR team — timing question: are you doing outbound email in-house or using an agency?" + +### 2. Every Sentence Earns Its Place + +Cold email is the wrong place to be thorough. Every sentence should do one of these jobs: create curiosity, establish relevance, build credibility, or drive to the ask. If a sentence doesn't do one of those — cut it. + +Read your draft aloud. The moment you hear yourself droning, stop and cut. + +### 3. Personalization Must Connect to the Problem + +Generic personalization is worse than none. "I saw you went to MIT" followed by a pitch has nothing to do with MIT. That's fake personalization. + +Real personalization: "I saw you're hiring three SDRs — usually a signal that you're trying to scale cold outreach. That's exactly the challenge we help with." + +The personalization must connect to the reason you're reaching out. + +### 4. Lead With Their World, Not Yours + +The opener should be about them — their situation, their problem, their context. Not about you or your product. + +- ❌ "We're a sales intelligence platform that..." +- ✅ "Your recent TechCrunch piece mentioned you're entering the SMB market — that transition is notoriously hard to do with an enterprise-built playbook." + +### 5. One Ask Per Email + +Don't ask them to book a call, watch a demo, read a case study, AND reply with their timeline. Pick one ask. The more you ask for, the less likely any of it happens. + +--- + +## Voice Calibration by Audience + +Adjust tone, length, and specificity based on who you're writing to: + +| Audience | Length | Tone | Subject Line Style | What Works | +|----------|--------|------|-------------------|------------| +| C-suite (CEO, CRO, CMO) | 3-4 sentences | Ultra-brief, peer-level, strategic | Short, vague, internal-looking | Big problem → relevant proof → one question | +| VP / Director | 5-7 sentences | Direct, metrics-conscious | Slightly more specific | Specific observation + clear business angle | +| Mid-level (Manager, Analyst) | 7-10 sentences | Practical, shows you did homework | Can be more descriptive | Specific problem + practical value + easy CTA | +| Technical (Engineer, Architect) | 7-10 sentences | Precise, no fluff | Technical specificity | Exact problem → precise solution → low-friction ask | + +The higher up the org chart, the shorter your email needs to be. A CEO gets 100+ emails per day. Three sentences and a clear question is a gift, not a slight. + +--- + +## Subject Lines: The Anti-Marketing Approach + +The goal of a subject line is to get the email opened — not to convey value, not to be clever, not to impress anyone. Just open it. + +The best cold email subject lines look like internal emails. They're short, slightly vague, and create just enough curiosity to click. + +### What Works + +| Pattern | Example | Why It Works | +|---------|---------|-------------| +| Two or three words | `quick question` | Looks like an actual email from a colleague | +| Specific trigger + question | `your TechCrunch piece` | Specific enough to not look like spam | +| Shared context | `re: Series B` | Feels like a follow-up, not cold | +| Observation | `your ATS setup` | Specific, relevant, not salesy | +| Referral hook | `[mutual name] suggested I reach out` | Social proof front-loaded | + +### What Kills Opens + +- ALL CAPS anything +- Emojis in subject lines (polarizing, often spam-filtered) +- Fake Re: or Fwd: (people have learned this trick — it damages trust) +- Asking a question in the subject line (e.g., "Are you struggling with X?") — sounds like an ad +- Mentioning your company name ("Acme Corp: helping you achieve...") +- Numbers that feel like blog headlines ("5 ways to improve your...") + +--- + +## Follow-Up Strategy + +Most deals happen in follow-ups. Most follow-ups are useless. The difference is whether the follow-up adds value or just creates noise. + +### Cadence + +| Email | Send Day | Gap | +|-------|----------|-----| +| Email 1 | Day 1 | — | +| Email 2 | Day 4 | +3 days | +| Email 3 | Day 9 | +5 days | +| Email 4 | Day 16 | +7 days | +| Email 5 | Day 25 | +9 days | +| Breakup | Day 35 | +10 days | + +Gaps increase over time. You're persistent but not annoying. + +### Follow-Up Rules + +**Each follow-up must have a new angle.** Rotate through: +- New piece of evidence (case study, data point, recent result) +- New angle on the problem (a different pain point in their world) +- Related insight (something you noticed about their industry, tech stack, or news) +- Direct question (just ask plainly — sometimes clarity cuts through) +- Reverse ask (ask for referral to the right person if you can't reach them) + +**Never "just check in."** "Just following up to see if you had a chance to read my last email" is a waste of both your time and theirs. If you have nothing new to add, don't send the email. + +**Don't reference all previous emails.** Each follow-up should stand alone. The prospect doesn't remember your earlier emails. Don't make them scroll. + +### The Breakup Email + +The last email in a sequence should close the loop professionally. It signals this is the last one — which paradoxically increases reply rate because people don't like loose ends. + +Example breakup: +> "I'll stop cluttering your inbox after this one. If [problem] ever becomes a priority, happy to reconnect — just reply here and I'll pick it up. +> +> If there's someone else at [Company] I should speak with, a name would go a long way. +> +> Either way — good luck with [whatever's relevant]." + +See `references/follow-up-playbook.md` for full cadence templates and angle rotation guide. + +--- + +## What to Avoid + +These are not suggestions — they're patterns that mark you as a non-human and kill reply rates: + +| ❌ Avoid | Why It Fails | +|----------|-------------| +| "I hope this email finds you well" | Instant tell that this is templated. Cut it. | +| "I wanted to reach out because..." | 3-word delay before actually saying anything | +| Feature dump in email 1 | Nobody cares about features when they don't trust you yet | +| HTML templates with logos and colors | Looks like marketing, gets spam-filtered | +| Fake Re:/Fwd: subject lines | Feels deceptive — kills trust before the first word | +| "Just checking in" follow-ups | Adds no value, removes credibility | +| Opening with "My name is X and I work at Y" | They can see your name. Start with something interesting. | +| Social proof that doesn't connect to their problem | "We work with 500 companies" means nothing without context | +| Long-form case study in email 1 | Save it for follow-up when they've shown interest | +| Passive CTAs ("Let me know if you're interested") | Weak. Ask a direct question or propose a specific next step. | + +--- + +## Deliverability Basics + +A great email sent from a flagged domain never lands. Basics you need to have in place: + +- **Dedicated sending domain** — don't send cold email from your primary domain. Use `mail.yourdomain.com` or `outreach.yourdomain.com`. +- **SPF, DKIM, DMARC** — all three must be configured and passing. Use mail-tester.com to verify. +- **Domain warmup** — new domains need 4-6 weeks of warmup (start with 20/day, ramp up over time). +- **Plain text emails** — or minimal HTML. Heavy HTML triggers spam filters. +- **Unsubscribe mechanism** — required legally (CAN-SPAM, GDPR). Include a simple opt-out. +- **Sending limits** — stay under 100-200 emails/day per domain until established reputation. +- **Bounce rate** — above 5% hurts deliverability. Verify email lists before sending. + +See `references/deliverability-guide.md` for domain warmup schedule, SPF/DKIM setup, and spam trigger word list. + +--- + +## Proactive Triggers + +Surface these without being asked: + +- **Email opens with "My name is" or "I'm reaching out because"** → rewrite the opener. These are dead-on-arrival openers. Flag and offer an alternative that leads with their world. +- **First email is longer than 150 words** → almost certainly too long. Flag word count and offer to trim. +- **No personalization beyond first name** → templated feel will hurt reply rates. Ask if there's a trigger or signal they can work with. +- **Follow-up says "just checking in" or "circling back"** → useless follow-up. Ask what new angle or value they can bring to that touchpoint. +- **HTML email template** → recommend plain text. Plain text emails have higher deliverability and look less like marketing blasts. +- **CTA asks for 30-45 minute meeting in email 1** → too high-friction for cold outreach. Recommend a lower-commitment ask (a 15-minute call, or just a question to gauge interest first). + +--- + +## Output Artifacts + +| When you ask for... | You get... | +|---------------------|------------| +| Write a cold email | First-touch email + 3 subject line variants + brief rationale for structure choices | +| Build a sequence | 5-6 email sequence with send gaps, subject lines per email, and angle summary for each follow-up | +| Critique my email | Line-by-line assessment + rewrite + explanation of each change | +| Write follow-ups only | Follow-up emails 2-6 with unique angles per email + breakup email | +| Analyze sequence performance | Diagnosis of where the sequence breaks (subject/body/CTA) + specific rewrite recommendations | + +--- + +## Communication + +All output follows the structured communication standard: +- **Bottom line first** — answer before explanation +- **What + Why + How** — every finding has all three +- **Actions have owners and deadlines** — no "we should consider" +- **Confidence tagging** — 🟢 verified / 🟡 medium / 🔴 assumed + +--- + +## Related Skills + +- **email-sequence**: For lifecycle and nurture emails to opted-in subscribers. Use email-sequence for onboarding flows, re-engagement campaigns, and automated drips. NOT for cold outreach — that's cold-email. +- **copywriting**: For marketing page copy. Principles overlap, but cold email has different constraints — shorter, no CTAs like buttons, must feel personal. +- **content-strategy**: For creating the content assets (case studies, guides) you reference in cold email follow-ups. Good follow-up sequences often link to content. +- **marketing-strategy-pmm**: For positioning and ICP definition.

Replace generic with specific. The content starts sounding like a person. + +### Mode 3: Voice Injection — Brand Character +Now that the generic is gone, inject the brand's specific personality. This is where "human" becomes *your brand's* human. + +Run all three in one pass when you have enough context. Split them when the client needs to see the audit before you edit. + +--- + +## Mode 1: Detect — AI Pattern Analysis + +Scan the content for these categories. Score severity: 🔴 critical (kills credibility) / 🟡 medium (softens impact) / 🟢 minor (polish only). + +See [references/ai-tells-checklist.md](references/ai-tells-checklist.md) for the comprehensive detection list. + +### The Core AI Tell Categories + +**1. Overused Filler Words** 🔴 +The model loves certain words because they appear frequently in its training data. Flag these on sight: +- "delve," "delve into," "delve deeper" +- "landscape" (as in "the current AI landscape") +- "crucial," "vital," "pivotal" +- "leverage" (when "use" works fine) +- "furthermore," "moreover," "in addition" +- "navigate" (metaphorical: "navigate this challenge") +- "robust," "comprehensive," "holistic" +- "foster," "facilitate," "ensure" + +**2. Hedging Chains** 🔴 +AI hedges constantly. It hedges because it doesn't know if it's right. Humans hedge sometimes — but not in every sentence. +- "It's important to note that..." +- "It's worth mentioning that..." +- "One might argue that..." +- "In many cases," "In most scenarios," +- "It goes without saying..." +- "Needless to say..." + +**3. Em-Dash Overuse** 🟡 +One or two em-dashes in a piece: fine. Em-dash in every other paragraph: AI fingerprint. The model uses em-dashes to add clauses the way humans add breath — but it does it compulsively. + +**4. Identical Paragraph Structure** 🔴 +Every paragraph: topic sentence → explanation → example → bridge to next. AI is remarkably consistent. Remarkably boring. Real writing has short paragraphs. Fragments. Asides. Digressions. Then it snaps back. The structure varies. + +**5. Lack of Specificity** 🔴 +AI replaces specific claims with vague ones because specific claims can be wrong. Look for: +- "Many companies" → which companies? +- "Studies show" → which studies? +- "Significantly improved" → improved by how much? +- "Leading brands" → name one +- "A lot of" → how many? + +**6. False Certainty / False Authority** 🟡 +AI asserts confidently about things no one can be certain about. "Companies that do X are more successful." According to what? This isn't humility — it's laziness dressed as confidence. + +**7. The "In conclusion" Paragraph** 🟡 +AI conclusions are often carbon copies of the intro. "In this article, we explored X, Y, and Z. By implementing these strategies, you can achieve..." No human concludes like this. Real conclusions either add something new or nail the exit line. + +--- + +## Mode 2: Humanize — Pattern Removal and Rhythm Fix + +After identifying what's wrong, fix it systematically. + +### Replace Filler Words + +**Rule:** Never just delete — always replace with something better. + +| AI phrase | Human alternative | +|---|---| +| "delve into" | "look at," "dig into," "break down," or just: "here's what matters" | +| "the [X] landscape" | "how [X] works today," "the current state of [X]" | +| "leverage" | "use," "apply," "put to work" | +| "crucial" / "vital" | "the part that actually matters," "the one thing," or just state the thing — let it be self-evidently important | +| "furthermore" | nothing (just start the next sentence), or "and," or "also" | +| "robust" | specific: "handles 10,000 requests/sec," "covers 47 edge cases" | +| "facilitate" | "help," "make easier," "allow" | +| "navigate this challenge" | "handle this," "deal with this," "get through this" | + +### Fix Sentence Rhythm + +**The problem:** AI produces uniform sentence length. Every sentence is 18-22 words. The ear goes numb. + +**The fix:** Deliberate variation. Read aloud. Then: +- Break long sentences into two +- Add a short sentence after a long one. Like this. +- Use fragments where they serve emphasis. Especially for emphasis. +- Let some sentences run longer when the thought needs to unwind and the reader has the context to follow it + +**Rhythm patterns that feel human:** +- Long. Short. Long, long. Short. +- Question? Answer. Proof. +- Claim. Specific example. So what? + +### Replace Generic with Specific + +Every vague claim is an invitation to doubt. Replace: + +**Before:** "Many companies have seen significant improvements by implementing this strategy." + +**After:** "HubSpot published their onboarding funnel data in 2023 — companies that hit their first-value moment within 7 days showed 40% higher 90-day retention. That's not a rounding error." + +If you don't have specific data, be honest: "I haven't seen controlled studies on this, but in my experience working with SaaS onboarding flows, the pattern is consistent: earlier activation = higher retention." + +Personal experience beats vague authority. Every time. + +### Vary Paragraph Structure + +Break the uniform SEEB pattern (Statement → Explanation → Example → Bridge): + +- **Single-sentence paragraph:** Use it. Emphasis needs air. +- **Question paragraph:** Pose a question. Then answer it. +- **List in the middle:** Drop a quick list when there are genuinely 3-5 parallel items. Then return to prose. +- **Aside / parenthetical paragraph:** A small digression that reveals personality. (Readers actually like these. It's the equivalent of a raised eyebrow mid-sentence.) +- **Confession:** "I got this wrong the first time." Instantly human. + +### Add Friction and Imperfection + +AI writing is too smooth. Too complete. Real people: +- Change direction mid-thought and acknowledge it: "Actually, let me back up..." +- Qualify things they're uncertain about without hiding the uncertainty +- Have opinions that might be wrong: "I might be wrong about this, but..." +- Notice things and say so: "What's interesting here is..." +- React: "Which, if you've ever tried to debug this, you know is maddening." + +--- + +## Mode 3: Voice Injection — Brand Character + +Humanizing removes AI. Voice injection makes it *yours*. + +### Read the Voice Blueprint First + +If `marketing-context.md` is available: read the brand voice section and writing examples. If not, ask for one example of content this brand loves. One. Then extract the patterns from it. + +**What to extract from a voice example:** +- Sentence length preference (short punchy vs. longer flowing?) +- Formality level (contractions? slang? industry jargon?) +- Use of humor (dry wit? self-deprecating? none?) +- Relationship stance (peer-to-peer? expert-to-student? provocateur?) +- Signature phrases or patterns + +See [references/voice-techniques.md](references/voice-techniques.md) for specific techniques for each voice type. + +### Voice Injection Techniques + +**1. Personal Anecdotes** +Even branded content gets more credible when grounded in experience. "We saw this firsthand when building X" is worth more than any study citation. + +**2. Direct Address** +Talk to the reader as "you." Not "users" or "teams" or "organizations." You. + +**3. Opinions Without Apology** +State your position. "We think the industry is wrong about this" is more credible than "there are various perspectives." Take the side. + +**4. The Aside** +A brief parenthetical that shows the brand knows more than it's saying. "This also affects API performance, but that's a separate rabbit hole." + +**5. Rhythm Signature** +Every brand has a rhythm. Some write in short staccato bursts. Some write long, winding sentences that spiral back on themselves. Find the rhythm from the examples and apply it consistently. + +### Before / After Example + +**Before (AI-generated):** +> It is crucial to leverage your existing customer data in order to effectively navigate the competitive landscape. Furthermore, by implementing a robust onboarding strategy, organizations can ensure that users achieve maximum value from the product and reduce churn significantly. + +**After (humanized):** +> Here's the thing nobody says out loud: most SaaS companies have the data to fix their churn problem. They just don't look at it until after customers leave. +> +> Your activation funnel is in there. Your best cohorts, your worst, the moment the drop-off happens. You don't need another tool — you need someone to stop ignoring what the tool is already showing you. +> +> Nail onboarding first. Everything else is downstream. + +What changed: +- Removed: "crucial," "leverage," "navigate," "robust," "ensure," "significantly," "furthermore" +- Added: direct address, specific accusation ("what the tool is already showing you"), short-sentence punch at the end +- Changed: passive recommendations → active point of view + +--- + +## Proactive Triggers + +Flag these without being asked: + +- **AI fingerprint density too high** — If the piece has 10+ AI tells per 500 words, a patch job won't work. Flag that the piece needs a full rewrite, not an edit. Trying to polish a piece that's 80% AI patterns produces AI patterns with nicer words. +- **Voice context missing** — If `marketing-context.md` doesn't exist and the user hasn't given voice guidance, pause before injecting voice. Ask for one example. Guessing the voice and being wrong wastes everyone's time. +- **Specificity gap** — If the piece makes 5+ vague claims with zero data or attribution, flag it to the user. You can make the prose flow better, but you can't invent specific proof. They need to provide it. +- **Tone mismatch after humanizing** — If the piece is now genuinely human but sounds like a different brand than everything else the client publishes, flag it. Consistency matters as much as quality. +- **Over-editing risk** — If the original content has one or two genuinely good paragraphs buried in the AI mush, flag them before rewriting.

Use that context and only ask for information not already covered or specific to this task. + +--- + +## Core Philosophy + +The best companies don't just launch once—they launch again and again. Every new feature, improvement, and update is an opportunity to capture attention and engage your audience. + +A strong launch isn't about a single moment. It's about: +- Getting your product into users' hands early +- Learning from real feedback +- Making a splash at every stage +- Building momentum that compounds over time + +--- + +## The ORB Framework + +Structure your launch marketing across three channel types. Everything should ultimately lead back to owned channels. + +### Owned Channels +You own the channel (though not the audience). Direct access without algorithms or platform rules. + +**Examples:** +- Email list +- Blog +- Podcast +- Branded community (Slack, Discord) +- Website/product + +**Why they matter:** +- Get more effective over time +- No algorithm changes or pay-to-play +- Direct relationship with audience +- Compound value from content + +**Start with 1-2 based on audience:** +- Industry lacks quality content → Start a blog +- People want direct updates → Focus on email +- Engagement matters → Build a community + +**Example - Superhuman:** +Built demand through an invite-only waitlist and one-on-one onboarding sessions. Every new user got a 30-minute live demo. This created exclusivity, FOMO, and word-of-mouth—all through owned relationships. Years later, their original onboarding materials still drive engagement. + +### Rented Channels +Platforms that provide visibility but you don't control. Algorithms shift, rules change, pay-to-play increases. + +**Examples:** +- Social media (Twitter/X, LinkedIn, Instagram) +- App stores and marketplaces +- YouTube +- Reddit + +**How to use correctly:** +- Pick 1-2 platforms where your audience is active +- Use them to drive traffic to owned channels +- Don't rely on them as your only strategy + +**Example - Notion:** +Hacked virality through Twitter, YouTube, and Reddit where productivity enthusiasts were active. Encouraged community to share templates and workflows. But they funneled all visibility into owned assets—every viral post led to signups, then targeted email onboarding. + +**Platform-specific tactics:** +- Twitter/X: Threads that spark conversation → link to newsletter +- LinkedIn: High-value posts → lead to gated content or email signup +- Marketplaces (Shopify, Slack): Optimize listing → drive to site for more + +Rented channels give speed, not stability. Capture momentum by bringing users into your owned ecosystem. + +### Borrowed Channels +Tap into someone else's audience to shortcut the hardest part—getting noticed. + +**Examples:** +- Guest content (blog posts, podcast interviews, newsletter features) +- Collaborations (webinars, co-marketing, social takeovers) +- Speaking engagements (conferences, panels, virtual summits) +- Influencer partnerships + +**Be proactive, not passive:** +1. List industry leaders your audience follows +2. Pitch win-win collaborations +3. Use tools like SparkToro or Listen Notes to find audience overlap +4. Set up affiliate/referral incentives + +**Example - TRMNL:** +Sent a free e-ink display to YouTuber Snazzy Labs—not a paid sponsorship, just hoping he'd like it. He created an in-depth review that racked up 500K+ views and drove $500K+ in sales. They also set up an affiliate program for ongoing promotion. + +Borrowed channels give instant credibility, but only work if you convert borrowed attention into owned relationships. + +--- + +## Five-Phase Launch Approach + +Launching isn't a one-day event. It's a phased process that builds momentum. + +### Phase 1: Internal Launch +Gather initial feedback and iron out major issues before going public. + +**Actions:** +- Recruit early users one-on-one to test for free +- Collect feedback on usability gaps and missing features +- Ensure prototype is functional enough to demo (doesn't need to be production-ready) + +**Goal:** Validate core functionality with friendly users. + +### Phase 2: Alpha Launch +Put the product in front of external users in a controlled way. + +**Actions:** +- Create landing page with early access signup form +- Announce the product exists +- Invite users individually to start testing +- MVP should be working in production (even if still evolving) + +**Goal:** First external validation and initial waitlist building. + +### Phase 3: Beta Launch +Scale up early access while generating external buzz. + +**Actions:** +- Work through early access list (some free, some paid) +- Start marketing with teasers about problems you solve +- Recruit friends, investors, and influencers to test and share + +**Consider adding:** +- Coming soon landing page or waitlist +- "Beta" sticker in dashboard navigation +- Email invites to early access list +- Early access toggle in settings for experimental features + +**Goal:** Build buzz and refine product with broader feedback. + +### Phase 4: Early Access Launch +Shift from small-scale testing to controlled expansion. + +**Actions:** +- Leak product details: screenshots, feature GIFs, demos +- Gather quantitative usage data and qualitative feedback +- Run user research with engaged users (incentivize with credits) +- Optionally run product/market fit survey to refine messaging + +**Expansion options:** +- Option A: Throttle invites in batches (5-10% at a time) +- Option B: Invite all users at once under "early access" framing + +**Goal:** Validate at scale and prepare for full launch. + +### Phase 5: Full Launch +Open the floodgates. + +**Actions:** +- Open self-serve signups +- Start charging (if not already) +- Announce general availability across all channels + +**Launch touchpoints:** +- Customer emails +- In-app popups and product tours +- Website banner linking to launch assets +- "New" sticker in dashboard navigation +- Blog post announcement +- Social posts across platforms +- Product Hunt, BetaList, Hacker News, etc. + +**Goal:** Maximum visibility and conversion to paying users. + +--- + +## Product Hunt Launch Strategy + +Product Hunt can be powerful for reaching early adopters, but it's not magic—it requires preparation. + +### Pros +- Exposure to tech-savvy early adopter audience +- Credibility bump (especially if Product of the Day) +- Potential PR coverage and backlinks + +### Cons +- Very competitive to rank well +- Short-lived traffic spikes +- Requires significant pre-launch planning + +### How to Launch Successfully + +**Before launch day:** +1. Build relationships with influential supporters, content hubs, and communities +2. Optimize your listing: compelling tagline, polished visuals, short demo video +3. Study successful launches to identify what worked +4. Engage in relevant communities—provide value before pitching +5. Prepare your team for all-day engagement + +**On launch day:** +1. Treat it as an all-day event +2. Respond to every comment in real-time +3. Answer questions and spark discussions +4. Encourage your existing audience to engage +5. Direct traffic back to your site to capture signups + +**After launch day:** +1. Follow up with everyone who engaged +2. Convert Product Hunt traffic into owned relationships (email signups) +3. Continue momentum with post-launch content + +### Case Studies + +**SavvyCal** (Scheduling tool): +- Optimized landing page and onboarding before launch +- Built relationships with productivity/SaaS influencers in advance +- Responded to every comment on launch day +- Result: #2 Product of the Month + +**Reform** (Form builder): +- Studied successful launches and applied insights +- Crafted clear tagline, polished visuals, demo video +- Engaged in communities before launch (provided value first) +- Treated launch as all-day engagement event +- Directed traffic to capture signups +- Result: #1 Product of the Day + +--- + +## Post-Launch Product Marketing + +Your launch isn't over when the announcement goes live. Now comes adoption and retention work. + +### Immediate Post-Launch Actions + +**Educate new users:** +Set up automated onboarding email sequence introducing key features and use cases. + +**Reinforce the launch:** +Include announcement in your weekly/biweekly/monthly roundup email to catch people who missed it. + +**Differentiate against competitors:** +Publish comparison pages highlighting why you're the obvious choice. + +**Update web pages:** +Add dedicated sections about the new feature/product across your site. + +**Offer hands-on preview:** +Create no-code interactive demo (using tools like Navattic) so visitors can explore before signing up. + +### Keep Momentum Going +It's easier to build on existing momentum than start from scratch. Every touchpoint reinforces the launch. + +--- + +## Ongoing Launch Strategy + +Don't rely on a single launch event. Regular updates and feature rollouts sustain engagement. + +### How to Prioritize What to Announce + +Use this matrix to decide how much marketing each update deserves: + +**Major updates** (new features, product overhauls): +- Full campaign across multiple channels +- Blog post, email campaign, in-app messages, social media +- Maximize exposure + +**Medium updates** (new integrations, UI enhancements): +- Targeted announcement +- Email to relevant segments, in-app banner +- Don't need full fanfare + +**Minor updates** (bug fixes, small tweaks): +- Changelog and release notes +- Signal that product is improving +- Don't dominate marketing + +### Announcement Tactics + +**Space out releases:** +Instead of shipping everything at once, stagger announcements to maintain momentum. + +**Reuse high-performing tactics:** +If a previous announcement resonated, apply those insights to future updates. + +**Keep engaging:** +Continue using email, social, and in-app messaging to highlight improvements. + +**Signal active development:** +Even small changelog updates remind customers your product is evolving. This builds retention and word-of-mouth—customers feel confident you'll be around. + +--- + +## Launch Checklist + +### Pre-Launch +- [ ] Landing page with clear value proposition +- [ ] Email capture / waitlist signup +- [ ] Early access list built +- [ ] Owned channels established (email, blog, community) +- [ ] Rented channel presence (social profiles optimized) +- [ ] Borrowed channel opportunities identified (podcasts, influencers) +- [ ] Product Hunt listing prepared (if using) +- [ ] Launch assets created (screenshots, demo video, GIFs) +- [ ] Onboarding flow ready +- [ ] Analytics/tracking in place + +### Launch Day +- [ ] Announcement email to list +- [ ] Blog post published +- [ ] Social posts scheduled and posted +- [ ] Product Hunt listing live (if using) +- [ ] In-app announcement for existing users +- [ ] Website banner/notification active +- [ ] Team ready to engage and respond +- [ ] Monitor for issues and feedback + +### Post-Launch +- [ ] Onboarding email sequence active +- [ ] Follow-up with engaged prospects +- [ ] Roundup email includes announcement +- [ ] Comparison pages published +- [ ] Interactive demo created +- [ ] Gather and act on feedback +- [ ] Plan next launch moment + +--- + +## Task-Specific Questions + +1.

Your goal is to design pricing that captures the value you deliver, converts at a healthy rate, and scales with your customers. + +Pricing is not math — it's positioning. The right price isn't the one that covers costs + margin. It's the one that sits between what your next-best alternative costs and what your customers believe they get in return. Most SaaS products are underpriced. This skill is about fixing that, clearly and defensibly. + +## Before Starting + +**Check for context first:** +If `marketing-context.md` exists, read it before asking questions. Use that context and only ask for what's missing. + +Gather this context: + +### 1. Current State +- Do you have pricing today? If so: what plans, what price points, what's the billing model? +- What's your conversion rate from trial/free to paid? (If known) +- What's your average revenue per customer? +- What's your monthly churn rate? + +### 2. Business Context +- Product type: B2B or B2C? Self-serve or sales-assisted? +- Customer segments: who are your best customers vs. casual users? +- Competitors: who do customers compare you to, and what do those cost? +- Cost structure: what does serving one customer cost you per month? + +### 3. Goals +- Are you designing, optimizing, or planning a price increase? +- Any constraints? (e.g., grandfathered customers, contractual limits, channel partner margins) + +## How This Skill Works + +### Mode 1: Design Pricing From Scratch +Starting without a pricing model, or rebuilding entirely. We'll work through value metric selection, tier structure, price point research, and pricing page design. + +### Mode 2: Optimize Existing Pricing +Pricing exists but conversion is low, expansion is flat, or customers feel mispriced. We'll audit what's there, benchmark, and identify specific improvements. + +### Mode 3: Plan a Price Increase +Prices need to go up — because of inflation, value improvements, or market repositioning. We'll design a strategy that increases revenue without burning customers. + +--- + +## The Three Pricing Axes + +Every pricing decision lives across three axes. Get all three right. + +``` + ┌─────────────────┐ + │ PACKAGING │ What's in each tier? + │ (what you get) │ + └────────┬────────┘ + │ + ┌────────┴────────┐ + │ VALUE METRIC │ What do you charge for? + │ (how it scales) │ + └────────┬────────┘ + │ + ┌────────┴────────┐ + │ PRICE POINT │ How much? + │ (the number) │ + └─────────────────┘ +``` + +Most teams skip straight to price point. That's backwards. Lock in the metric first, then packaging, then test the number. + +--- + +## Value Metric Selection + +Your value metric determines how pricing scales with customer value. Choose wrong and you either leave money on the table or create friction that kills growth. + +### Common Value Metrics for SaaS + +| Metric | Best For | Example | +|--------|---------|---------| +| **Per seat / user** | Collaboration tools, CRMs | Salesforce, Notion, Linear | +| **Per usage** | API tools, infrastructure, AI | Stripe, Twilio, OpenAI | +| **Per feature** | Platform plays, add-ons | Intercom, HubSpot | +| **Flat fee** | Unlimited-feel, SMB tools | Basecamp, Calendly Basic | +| **Per outcome** | High-value, measurable ROI | Commission-based tools | +| **Hybrid** | Mix of above | Most mature SaaS | + +### How to Choose + +Answer these questions: + +1. **What makes a customer willing to pay more?** → That's your value metric +2. **Does the metric scale with their success?** → If they grow, you grow +3. **Is it easy to understand?** → Complexity kills conversion +4. **Is it hard to game?** → Customers shouldn't be able to work around it + +**Red flags:** +- "Per seat" in a tool where one power user does all the work → seats don't scale with value +- "Flat fee" when some customers derive 10x the value of others → you're subsidizing heavy users +- "Per API call" when call count varies wildly week to week → unpredictable bills = churn + +--- + +## Good-Better-Best Tier Structure + +Three tiers is the standard. Not because of tradition — because it anchors perception. + +### Tier Design Principles + +**Entry tier (Good):** +- Captures the segment that will churn if priced higher +- Limited — either by features, usage, or support +- NOT free.

At what price would this product be so cheap you'd question its quality? +2. At what price would this product be a bargain — great deal? +3. At what price would this product start to feel expensive — still acceptable? +4. At what price would this product be too expensive to consider? + +**Interpret the results:** Plot the four curves. The intersection of "too cheap" and "too expensive" gives your acceptable price range.

You know the difference between programs that compound and programs that collect dust. Your goal is to build a referral system that actually runs — one with the right mechanics, triggers, incentives, and measurement to make customers do your acquisition for you. + +## Before Starting + +**Check for context first:** +If `marketing-context.md` exists, read it before asking questions. Use that context and only ask for information not already covered. + +Gather this context (ask if not provided): + +### 1. Product & Customer +- What are you selling? (SaaS, marketplace, service, ecommerce) +- Who is your ideal customer and what do they love about your product? +- What's your average LTV? (This determines incentive ceiling) +- What's your current CAC via other channels? + +### 2. Program Goals +- What outcome do you want? (More signups, more revenue, brand reach) +- Is this B2C or B2B? (Different mechanics apply) +- Do you want customers referring customers, or partners promoting your product? + +### 3. Current State (if optimizing) +- What program exists today? +- What are the key metrics? (Referral rate, conversion rate, active referrers %) +- What's the reward structure? +- Where does the loop break down? + +--- + +## How This Skill Works + +### Mode 1: Design a New Program +Starting from scratch. Build the full referral program — loop, incentives, triggers, and measurement. + +**Workflow:** +1. Define the referral loop (4 stages) +2. Choose program type (customer referral vs. affiliate) +3. Design the incentive structure (what, when, for whom) +4. Identify trigger moments (when to ask for referrals) +5. Plan the share mechanics (how referrals actually happen) +6. Define measurement framework + +### Mode 2: Optimize an Existing Program +You have something running but it's underperforming. Diagnose where the loop breaks. + +**Workflow:** +1. Audit current metrics against benchmarks +2. Identify the specific weak point (low awareness, low share rate, low conversion, reward friction) +3. Run a focused fix — don't redesign everything at once +4. Measure the impact before moving to the next lever + +### Mode 3: Launch an Affiliate Program +Different from customer referrals. Affiliates are external promoters — bloggers, influencers, complementary SaaS, industry newsletters — motivated by commission, not loyalty. + +**Workflow:** +1. Define affiliate tiers and commission structure +2. Identify and recruit initial affiliate partners +3. Build the affiliate toolkit (links, assets, copy) +4. Set tracking and payout mechanics +5. Onboard and activate your first 10 affiliates + +--- + +## Referral vs. Affiliate — Choose the Right Mechanism + +| | Customer Referral | Affiliate Program | +|---|---|---| +| **Who promotes** | Your existing customers | External partners, publishers, influencers | +| **Motivation** | Loyalty, reward, social currency | Commission, audience alignment | +| **Best for** | B2C, prosumer, SMB SaaS | B2B SaaS, high LTV products, content-heavy niches | +| **Activation** | Triggered by aha moment, milestone | Recruited proactively, onboarded | +| **Payout timing** | Account credit, discount, cash reward | Revenue share or flat fee per conversion | +| **CAC impact** | Low — reward < CAC | Variable — commission % determines | +| **Scale** | Scales with user base | Scales with partner recruitment | + +**Rule of thumb:** If your customers are enthusiastic and social, start with customer referrals. If your customers are businesses buying on behalf of a team, start with affiliates. + +--- + +## The Referral Loop + +Every referral program runs on the same 4-stage loop. If any stage is weak, the loop breaks. + +``` +[Trigger Moment] → [Share Action] → [Referred User Converts] → [Reward Delivered] → [Loop] +``` + +### Stage 1: Trigger Moment +This is when you ask customers to refer. Timing is everything. + +**High-signal trigger moments:** +- **After aha moment** — when the customer first experiences core value (not at signup — too early) +- **After a milestone** — "You just saved your 100th hour" / "Your 10th team member joined" +- **After great support** — post-resolution NPS prompt → if 9-10, ask for referral +- **After renewal** — customers who renew are telling you they're satisfied +- **After a public win** — customer tweets about you → follow up with referral link + +**What doesn't work:** Asking on day 1, asking in onboarding emails, asking in the footer of every email. + +### Stage 2: Share Action +Remove every possible point of friction. + +- Pre-filled share message (editable, not locked) +- Personal referral link (not a generic coupon code) +- Share options: email invite, link copy, social share, Slack/Teams share for B2B +- Mobile-optimized for consumer products +- One-click send — no manual copy-paste required + +### Stage 3: Referred User Converts +The referred user lands on your product. Now what? + +- Personalized landing ("Your friend Alex invited you — here's your bonus...") +- Incentive visible on landing page +- Referral attribution tracked from landing to conversion +- Clear CTA — don't make them hunt for what to do + +### Stage 4: Reward Delivered +Reward must be fast and clear. Delayed rewards break the loop. + +- Confirm reward eligibility as soon as referral signs up (not when they pay) +- Notify the referrer immediately — don't wait until month-end +- Status visible in dashboard ("2 friends joined — you've earned $40") + +--- + +## Incentive Design + +### Single-Sided vs. Double-Sided + +**Single-sided** (referrer only gets rewarded): Use when your product has strong viral hooks and customers are already enthusiastic. Lower cost per referral. + +**Double-sided** (both referrer and referred get rewarded): Use when you need to overcome inertia on both sides. Higher cost, higher conversion. Dropbox made this famous. + +**Rule:** If your referral rate is <1%, go double-sided. If it's >5%, single-sided is more profitable. + +### Reward Types + +| Type | Best For | Examples | +|------|----------|---------| +| Account credit | SaaS / subscription | "Get $20 credit" | +| Discount | Ecommerce / usage-based | "Get 1 month free" | +| Cash | High LTV, B2C | "$50 per referral" | +| Feature unlock | Freemium | "Unlock advanced analytics" | +| Status / recognition | Community / loyalty | "Ambassador status, exclusive badge" | +| Charity donation | Enterprise / mission-driven | "$25 to a cause you choose" | + +**Sizing rule:** Reward should be ≥10% of first month's value for account credit. For cash, cap at 30% of first payment. Run `scripts/referral_roi_calculator.py` to model reward sizing against your LTV and CAC. + +### Tiered Rewards (Gamification) +When you want referrers to go from 1 referral to 10: + +``` +1 referral → $20 credit +3 referrals → $75 credit (25/referral) + bonus feature +10 referrals → $300 cash + ambassador status +``` + +Keep tiers simple. Three levels maximum. Each tier should feel meaningfully better, not just slightly better. + +--- + +## Optimization Levers + +Don't optimize randomly.

Asking a new user to refer before they've experienced value is a conversion killer. Move trigger to post-aha moment. +- **Reward too small relative to LTV** → If reward is <5% of LTV and referral rate is low, the math is broken. Surface the sizing issue. +- **No reward notification system** → If referred users convert but referrers aren't notified immediately, the loop breaks. Flag the need for instant notification. +- **Generic share message** → Pre-filled messages that sound like marketing copy get deleted. Flag and rewrite in first-person customer voice. +- **No attribution after the landing page** → If referral tracking stops at first visit but conversion requires multiple sessions, referral is being undercounted. Flag tracking gap. +- **Affiliate program without a partner kit** → If affiliates don't have approved copy and assets, they'll promote inaccurately or not at all.
