Frequently Asked Questions

What does this validation checklist cover?

Six sections: the problem, the market, the customer, competition and alternatives, business model, and execution risk — 22 checks in total, based on the questions that most often kill startups before or after launch.

Is this checklist free, and do I need to sign up?

Yes, completely free with no signup. Your progress is saved locally in your browser so you can come back to it.

Can I export or share my checklist?

Yes — use the "Copy as Markdown" button to copy your checklist, including checked/unchecked state, and paste it into a doc, README, or investor update.

I checked every box — does that mean my idea is validated?

It means you've asked the right questions, not that the answers are correct. The hardest box — "the problem is real" — is easy to check from a hunch and hard to check with evidence. Our free Idea Validator searches live complaints from Reddit and Hacker News so you can back that box up with real quotes instead of assumptions.
