Vouch

Have an idea you want to build? Vouch helps you test it with real customers first.

Turn a one-sentence idea into the assumptions that matter most. Prepare discovery interviews, share a link customers can answer, and turn their responses into evidence. Vouch helps you reach a clear yes, no, or not yet—so your next step is grounded in what customers actually said.

For indie makers, founders and product teams. Your first idea is free, with no credit card required. Pro is $19/month; Team is $49/seat/month.
