5 things founders mistake for validation

5 things founders mistake for validation People love the demo A demo shows what you can build. It doesn't show whether anyone will pay for it. The best demo I ever gave was for a product that had zero paying customers six months later. People respond to competence. That's not the same as demand. Everyone I talked to said they'd use it They were being polite. Ask someone if they'd use a free product that solves a problem they vaguely have and they'll almost always say yes. The question isn't "would you use it." It's "will you pay for it right now." Those two questions have very different answer rates. We have 200 waitlist signups A waitlist signup costs the person nothing. No money, minimal time, zero commitment. I've seen waitlists of 500 people convert to three paying customers. Waitlists measure curiosity. Curiosity is not a business. The market is huge TAM/SAM/SOM math feels like validation because it's real numbers about a real thing. But a big market doesn't mean your slice is accessible, ready, or interested in you specifically. In 2001 I co-founded the world's first real-money mobile gambling platform. The market was enormous. It was also five years away from existing. Market size tells you the ceiling. It doesn't tell you if there's a floor. A big company does something similar This one feels like proof of concept. If someone else built it, the problem must be real. Maybe. But it also means competition exists, the market may already be served, and "similar" almost never means "identical to what you're building." The existence of Salesforce did not validate every CRM startup that came after it. The only thing that validates an idea is someone paying for it. Everything else is encouragement.
