Startup Idea Validator

🔵 Stable🕐 updated 2026-06-21 🔷 SkillSpec L3 pm-founders

Pressure-test a startup idea the way a sharp investor or co-founder would — problem, market, wedge, moat, why-now, and the fastest cheap way to test it. Use when asked to validate a startup idea, evaluate a business idea, stress-test a concept, or decide whether something is worth building. Produces an honest assessment with the strongest case, the killer risks, and the next experiment to run — not cheerleading.

What to give it

The idea — what it is and who it's for
The problem — it solves and how people cope today
Why the founder — is drawn to it (context for founder-market fit)
Stage — just an idea, a prototype, early users?

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

Steel-mans the idea before critiquing it
Names specific killer assumptions, not generic "execution risk"
Answers "why doesn't this already exist?"
Ends with a concrete, cheap, this-week experiment

⚠️ What it refuses to do

Cheerleading (validating because the founder wants a yes)
Generic critique that applies to any startup
Recommending a 6-month build as the "test"
A verdict with no path forward
