How it works

From assumption to evidence in three stages.

A focused validation sprint typically takes two weeks. Here's the loop you'll run.

01

Surface assumptions

Describe your idea and target customer. Vouch generates a ranked list of Desirable, Viable and Feasible assumptions — the beliefs that must be true for the idea to work.

Each assumption gets an importance score and an evidence score. The riskiest, least-supported beliefs go first.

Day 1 · 15 minutes · → 3–5 ranked assumptions

02

Run discovery interviews

Open the side panel in Meet, Zoom or Teams. Vouch listens, detects which stage you're in, and suggests follow-ups in real time.

Tags, triggers and jargon sync back to your workspace. After every five conversations, Vouch synthesizes your beliefs and tells you what's still unanswered.

Days 2–10 · 5–10 calls · → Tagged transcripts + belief synthesis

03

Score, pilot, decide

Compare segments side-by-side with weighted Market / Product / Customer scores. Send a learning-focused pilot. Export a PDF for the team.

If the evidence holds, build with confidence. If it doesn't, kill the idea early and move on — that's the win.
