Startup Idea Validator
🔵 Stable🕐 updated 2026-10-06
🔷 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 changed
🗣 Say this to your agent
“Validate a startup idea.”“Evaluate a business idea.”“Stress-test a concept.”“Decide whether something is worth building.”
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
