Founder-Market Fit Skill

The strongest founder stories aren't résumés — they show an earned secret: something this founder knows or can do that others can't, and why that makes them the right person to win this market now. This skill builds that narrative.

Working from a brief

Given a thin bio, draft the full narrative anyway, drawing out the strongest plausible angle and marking inferred details (assumed — confirm). Never refuse for "not impressive enough background"; find the genuine edge in what's there. No placeholders.

Required Inputs

Ask for (if not already provided):

• The founder(s)' background — work, what they built, what they obsess over
• The idea / market and how they came to it
• The earned secret — what they learned the hard way that the market doesn't know
• Target (a VC pitch, a YC/accelerator application, a recruiting narrative)

Output Format

1. The one-line founder-market fit

"[Founder] is the right person to build [this] because [earned insight]" — in a single, specific sentence.

2. The story (3 beats)

• Origin — how they collided with this problem (lived it, built near it, obsessed over it)
• The secret — what they learned that others haven't, stated as a concrete insight not a platitude
• The proof — evidence they can execute: what they've already built, shipped, or learned

3. Why now, why you

Tie the founder's timing and capability to the market's why-now. The reader should feel this is inevitable for this team.

4. Application-ready answers (if YC/accelerator)

Crisp answers to the classic prompts:

• What's your unfair advantage / what do you understand that others don't?
• Why did you pick this idea? How do you know people want it?
• What have you built before / why will you out-execute?

Quality Checks

• The fit is shown through a specific earned secret, not a list of credentials
• Every claim is concrete (a thing built/shipped/learned), not adjectives ("passionate", "driven")
• Ties founder capability to the market's why-now
• Honest — strengthens a real background rather than inventing one

Anti-Patterns

• A résumé in prose ("10 years at BigCo, then...")
• Vague passion claims with no evidence
• Borrowed secrets (industry truisms anyone could state)
• Overclaiming — investors discount stories that don't ring true
