Skills

Market Sizing

Builds credible TAM/SAM/SOM analysis — the kind that earns investor trust rather than raising eyebrows.

What it does:

• Calculates TAM/SAM/SOM using top-down, bottom-up, or both approaches
• Validates market claims against external sources (analyst reports, government data, industry stats)
• Stress-tests assumptions with sensitivity analysis and confidence-based range widening
• Runs a 22-item self-check against common market sizing pitfalls
• Cross-checks every figure across the analysis before writing the report, so the numbers agree with each other
• Has a separate reviewer try to contradict the finished sizing, and shows every finding it can source

What to provide: A pitch deck, financial model, market data, or just describe the business (product, target customer, geography, pricing). The skill will research external sources to validate and build the estimate.

What you get back: A structured report with TAM/SAM/SOM figures (top-down and/or bottom-up), sensitivity ranges showing best/worst case, a scored self-check against common pitfalls, and coaching commentary on what will hold up in diligence.

Example prompts:

• "Use the market-sizing skill — here's the deck for Acme Corp, can you validate their market sizing?"
• "Use the market-sizing skill on a fintech startup in the payments space targeting SMBs in Europe."
• "Use the market-sizing skill — and show me what happens if the customer count is 30% lower."

Deck Review

Reviews pitch decks against current investor best practices, calibrated by stage (pre-seed, seed, Series A).

What it does:

• Scores 35 criteria across 7 categories (pass/fail/warn/not_applicable)
• Detects fundraising stage and applies stage-specific expectations
• Reviews each slide from the investor's perspective with specific, actionable feedback
• Grounds every recommendation in a named best-practice principle
• Assembles a scored report with overall deck readiness assessment

What to provide: A pitch deck in any format — PDF, PowerPoint, markdown, or text descriptions of your slides.

What you get back: A slide-by-slide review from the investor's perspective, a scored checklist (35 criteria across 7 categories), an overall readiness rating (strong/solid/needs work/major revision), and coaching on the highest-leverage changes to make before sending.

Example prompts:

• "Use the deck-review skill on our seed deck."
• "Use the deck-review skill — is this ready to send to investors? We're raising a pre-seed."
• "Use the deck-review skill on these slides: Slide 1 is our company intro with the tagline 'AI-powered compliance for fintechs'..."

IC Simulation

Simulates a realistic VC Investment Committee discussion with three partner archetypes debating a startup's merits, concerns, and deal terms -- scored across 28 dimensions.

What it does:

• Simulates three distinct partner perspectives: The Visionary (markets/timing), The Operator (execution/GTM), The Analyst (unit economics/financials)
• Forms each partner's view independently, so they genuinely disagree rather than echoing one another
• Scores 28 dimensions across 7 categories (team, market, product, business model, financials, risk, fund fit)
• Checks portfolio conflicts against the fund's existing investments
• Can simulate a named fund, researching its thesis and portfolio first
• Imports prior market-sizing and deck-review artifacts for grounded analysis

What to provide: A pitch deck, financial model, data room contents, or a verbal description of the business. Optionally, name a specific fund to simulate (e.g. "How would Sequoia evaluate us?"). Works best after running market sizing and/or deck review first — those artifacts are imported automatically.

What you get back: A simulated IC debate with three distinct partner voices, a conviction score across 28 dimensions, a consensus verdict (invest / more diligence / decline / decline — hard pass), portfolio conflict analysis, and coaching on exactly what to prepare before a real IC meeting.

Example prompts:

• "Use the ic-sim skill to simulate an IC discussion for our startup."
• "Use the ic-sim skill — how would partners at a fund like this discuss our company?"
• "I just did market sizing and a deck review — now use the ic-sim skill."
