How to validate your app idea before building

Interview users who already pay to solve the problem some other way. If nobody has a workaround, you probably do not have a market.

Compliments are free. Pre-orders, waitlist signups and letters of intent are the signals we trust before writing production code.

Agree upfront on the result that would make you stop. Founders who set that number early spend far less money learning the same lesson.
