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.
Before the first build—or the next feature
You can build a scheduling app this weekend. The unanswered question is whether one specific buyer has a costly scheduling problem and a reason to switch.
A customer, a risky assumption and a next interview—not a unicorn prediction.
01 · Choose a candidate customer
Turn a broad market into a profile you can test. AI suggestions are a starting point, not verified demand.
Explore candidate customers02 · Ask about real behaviour
Prepare questions about past problems, current alternatives, costs and decision makers.
Prepare interview questions03 · Test the next commitment
Use a clear offer and review evidence before deciding to build or scale.
Follow the validation checklist
Keep the evidence together
Continue with assumptions, interview notes and evidence in a Vouch workspace.
Start my workspace Customer and offer research- How does Vouch help founders & ai builders?
- Idea validation for founders using AI builders: test the customer, problem and offer before automating execution.
- Does AI output prove customer demand?
- No. Generated assumptions and customer profiles are hypotheses. Customer conversations and concrete commitments provide evidence to evaluate them.
- Where should I start?
- Start with one idea or offer and one candidate customer. Run a risk check, prepare non-leading interview questions, then record what you learn in a Vouch workspace.
One evidence loop. Different decisions.
