Preuve AI (Formerly Test Your Idea) validates startup ideas before you build. Describe your concept in plain language and 10 specialized AI agents scan 50+ live data sources to produce a sourced viability report in under five minutes.

Each report covers competitor landscape, total addressable market sizing, demand and trend signals, pricing benchmarks, key risk assumptions, and a composite viability score from 0 to 100. Every data point links to its source - Google Trends, Reddit, Product Hunt, Trustpilot, app stores, and more. If the data cannot verify a claim, it is not included.

A free scan delivers a quick overview with viability score. The Deep Analysis ($29) unlocks all 13 report sections including go-to-market playbook, community signals, pivot recommendations and 3x iterations. The Investor Package ($499) generates five investor-ready deliverables: pitch deck, investment memo, financial model, DD checklist, and pitch prep guide.
