Used by 8,000+ entrepreneurs. Crunchbase for funding. Reddit for real complaints. G2 for what users actually say. Every claim links to its source. CB Insights found 42% of startups fail from no market need. That is the blind spot Preuve catches. You leave with the 3 reasons it could fail, the 2 reasons it could work, and a verdict you can defend to a business partner, an investor, or yourself. ## Editorial stats - 8,000+ ideas scanned - 60+ live data sources (Crunchbase, Google Trends, Reddit, Product Hunt, G2, and more) - 13 industries covered - Free scan average: under a minute - Median viability score: 54/100 - 17.5% of ideas earn a GO verdict at 70 or above - Founded: 2026 - Bootstrapped solo product ## How the AI works This is not a ChatGPT prompt. It is an agentic RAG pipeline. 1. **Parallel web search** — Autonomous AI agents search the live web in parallel across 60+ sources. 2. **Filter and verify** — Junk sources are filtered. Competitors, funding, market size, and community signals are cross-referenced. 3. **Score and synthesize** — Verified facts feed a reasoning model. Standard code handles deterministic logic. Every claim links to its source. Preuve never invents competitors, never guesses market sizes, never fabricates data. It synthesizes facts already retrieved and verified from live sources. ## Why it exists The entrepreneurs who survive validate first. ChatGPT will tell you your idea is brilliant. Friends will be polite. Six months in, you discover what the market already knew. Preuve was built to catch that blind spot before you build. From Vincent Forat, founder of Preuve AI: the products that worked found the problems early. The ones that flopped had blind spots nobody caught. ## Founder Preuve is built by Vincent Forat, a solo founder based in Paris. 5 years in B2B growth marketing. He watched too many founders burn months on ideas nobody wanted, then built the validator that checks real market data instead of guessing. - LinkedIn: https://www.linkedin.com/in/vincent-forat/ - X: https://x.com/VincentBuilds - Founder profile: https://preuve.ai/author/vincent - Trustpilot: https://www.trustpilot.com/review/preuve.ai - Product Hunt: https://www.producthunt.com/products/preuve-ai - There's An AI For That: https://theresanaiforthat.com/ai/preuve-ai/ ## Common questions ### What is Preuve AI?

Standard code handles deterministic logic. The AI handles only the heavy synthesis. Every claim in the report links to its source. ### Is Preuve AI just a ChatGPT wrapper?
