Vouch · Dream big. Test small.
Your next big idea starts here.
The next unicorn? Maybe. The next customer conversation? Definitely.
Before you ask AI to build your company, find out what has to be true for someone to want it.

Go on, try it with your idea
Type it the way you'd explain it to a friend. Vouch shows you the three things most likely to sink it, and the first question to ask a real customer.
From ambition to evidence
A big vision. One testable next step.
Find the fragile assumption
Name the customer, the problem and the belief that would make the whole idea fall apart.
Ask a real buyer
Find out what they did last time, what it cost and what they already use. Compliments are not demand.
Earn the next build
Test a concrete commitment: a pilot, time on the calendar or an introduction. Let the evidence shape what you build.
Using an AI company builder? Bring it a better brief.
Vouch is the customer-evidence step: rank your risks, prepare interviews and keep what you learn in one workspace. Take that evidence into your company builder so execution follows a real problem, not just a convincing prompt.
Already built something? Test the buyer, the problem and the offer before building more. Vouch works alongside your existing tools; no company-builder integration is required or implied.
