About TestYourIdeaHQ
Founder
Vincent Forat
Founder & CEO
5 years in B2B growth marketing. Helped startups and scale-ups build acquisition systems, align sales and marketing ops, and implement CRMs (HubSpot, Pipedrive, Salesforce). Based in Paris, France.
Watched too many founders burn months on ideas nobody wanted. Built the validation tool he wished existed: one that checks real market data instead of guessing.
What we build
Preuve AI scores startup ideas against 40+ live data sources. Competitors, market size, funding data, demand signals. Every data point links to its source. Not AI guesses, receipts.
For founders
preuve.ai
Full validation report in 5 minutes. Viability score, competitor map, market sizing, risk factors. Founders validate before they build.
For agencies
testyourideahq.com
White-label widget on your site. Founders validate their idea before booking a call. You see their score, competitors, and market data. Bad leads filter themselves.
How the AI works
This is not a ChatGPT prompt. It is an agentic RAG pipeline built for accuracy.
1. Parallel web search
Autonomous AI agents search 40+ live sources in parallel: Crunchbase, Google Trends, Reddit, Product Hunt, G2, and more.
2. Filter & verify
Junk sources are filtered. Competitors, funding, market size, and community signals are extracted and cross-referenced.
3. Score & synthesize
Verified data feeds a reasoning model that scores the idea. Every claim links to its source. Standard code handles the deterministic logic.
Stage of development
The consumer product (preuve.ai) launched January 2026. The agency platform (testyourideahq.com) launched February 2026. Both are live, revenue-generating, and bootstrapped.
