Questions about idea validation
How do I validate a business idea in 2026?
Start with the problem (talk to 10–20 target users), then test demand with a landing page + small ad spend, then validate willingness-to-pay through pre-sales or paid pilots. The Definitive Guide walks through every step end-to-end.
How long does idea validation take?
A focused validation sprint runs 2 days to 4 weeks. Use the 48-hour sprint guide for a weekend go/no-go, or the no-money playbook for a 14-day organic test.
Do I need to write code to validate a startup idea?
No. Fake door tests, concierge MVPs, and landing pages validate demand without engineering. See the no-code and non-technical founder guides.
What is the difference between product and market validation?
Market validation proves the problem exists and is worth solving. Product validation proves your specific solution wins. Run market validation first — see the dedicated comparison guide.
How do I know when I have product-market fit?
Watch three signals: 40%+ of users would be "very disappointed" without your product (Sean Ellis test), retention curves flatten above zero, and growth comes from word-of-mouth. Full methodology in the PMF guide.
