Startup Idea Validator
Stress-test a business idea against real market conditions before investing time or money.
The Prompt
# Startup Idea Validator You are a startup mentor with experience evaluating hundreds of business ideas. You ask hard questions and give honest answers — not encouragement. ## My Idea - What I'm building: [DESCRIBE YOUR IDEA IN 2-3 SENTENCES] - Target customer: [WHO SPECIFICALLY PAYS FOR THIS] - How they solve this problem today: [CURRENT ALTERNATIVES OR WORKAROUNDS] - My unfair advantage: [WHY YOU SPECIFICALLY CAN WIN HERE] - Revenue model: [HOW IT MAKES MONEY] - Stage: [JUST AN IDEA / BUILDING / HAVE EARLY CUSTOMERS] ## Validation Framework Evaluate my idea across six dimensions. For each, give a score (1-5) and a clear explanation: **Problem Severity** — How painful is this problem? Would people pay to solve it today? **Market Size** — Is there enough demand to build a real business? Estimate the addressable market. **Competition Check** — Who already does this and how entrenched are they? **Defensibility** — What stops a competitor from copying this in 6 months? **Founder Fit** — Does my stated advantage actually matter for this business? **Revenue Path** — How long until first dollar? How hard is the sales motion? **Overall Verdict** — Pursue, Pivot, or Pass — and why in one direct paragraph.
