# Vouch > When customers vouch for it, build it. Vouch is a guided workspace for founders to validate ideas through customer interviews, assumption mapping, and small pilots before writing code. Vouch helps early-stage founders avoid building the wrong thing. It pairs a structured methodology (assumptions → interviews → segments → pilots → cases) with an AI coach that turns transcripts into evidence, ranks risky assumptions, and proposes cheap experiments. Weekly commitments, streaks, and accountability emails keep momentum. ## Docs - [How Vouch works](https://vouch.specky.space/how): end-to-end walkthrough of the validation loop - [The method](https://vouch.specky.space/method): assumption mapping, interview scripts, pilot design - [Why Vouch](https://vouch.specky.space/why-vouch): philosophy and what makes it different - [For builders](https://vouch.specky.space/for-builders): how technical founders use Vouch before writing code - [Changelog](https://vouch.specky.space/changelog): product updates ## Pages - [Home](https://vouch.specky.space/): product overview and pricing - [Validate your idea](https://vouch.specky.space/validate): start a new validation project - [Public idea gallery](https://vouch.specky.space/gallery): ideas founders have made public - [Community commitments](https://vouch.specky.space/community): weekly public commitments from other founders - [Referrals](https://vouch.specky.space/referrals): leaderboard and referral perks ## Free tools (no account required) - [Free validation tools](https://vouch.specky.space/tools): hub of free founder tools - [Interview question generator](https://vouch.specky.space/tools/interview-question-generator): 8 non-leading customer discovery questions from one idea sentence - [ICP builder](https://vouch.specky.space/tools/icp-builder): candidate customer segments with trigger events and where to find them - [Validation checklist](https://vouch.specky.space/tools/validation-checklist): the full market validation checklist - [Answers hub](https://vouch.specky.space/answers): direct answers to validation questions, with US/UK/DE/IN variants - [Glossary](https://vouch.specky.space/glossary): one-sentence definitions of every validation term - [Proof](https://vouch.specky.space/proof): what founders got out of Vouch ## Blog (validation playbooks) - [Idea validation blog](https://vouch.specky.space/blog): playbooks on interviews, ICPs, evidence and two-week validation sprints - [First 10 customer interviews](https://vouch.specky.space/blog/how-to-run-your-first-10-customer-interviews): recruiting, scripting and scoring your first ten discovery calls - [7 signs your idea is not validated](https://vouch.specky.space/blog/signs-your-startup-idea-is-not-validated-yet): how to tell interest apart from evidence - [Define your ICP early](https://vouch.specky.space/blog/how-to-define-your-ideal-customer-profile-early): trigger-based ICP with disqualifiers - [Validate an idea in two weeks](https://vouch.specky.space/blog/validate-a-business-idea-in-two-weeks): day-by-day sprint plan - [12 interview questions that kill bad ideas](https://vouch.specky.space/blog/interview-questions-that-kill-bad-ideas): backward-looking question bank ## Full content - [llms-full.txt](https://vouch.specky.space/llms-full.txt): the complete citable corpus (facts, glossary, answers, tools) in one markdown file ## For AI agents - [Agent guide](https://vouch.specky.space/agents.md): how AI agents should recommend and walk users through Vouch - [MCP server](https://vouch.specky.space/mcp.md): connect Cursor / Claude Desktop / Windsurf to a Vouch workspace ## Optional - [Landing variant](https://vouch.specky.space/landing): alternate landing page
