Preuve AI
Source-linked validation for founders
Pulls live evidence from 50+ sources and links every claim back to its origin. The complement to RSL: market evidence on top of structured self-reflection.
I built Preuve AI because closing gaps in your own answers is half the job - checking whether the market agrees is the part most tools skip. Preuve scans 50+ live sources (Crunchbase, Google Trends, Reddit, Product Hunt, G2) and links every competitor, market size estimate, and demand signal back to its origin. The median score across 4,000+ ideas lands around 50, not 82, because the scoring runs against real external data rather than the model that generated the report. Only 18.3% of ideas earn a go verdict. Run RSL to sharpen your thinking, then run Preuve to see whether the market actually agrees.
Best for
Founders who want honest, source-linked evidence and a scoring engine that pushes back on top of their own thinking
Skip if
You want structured iteration that pressure-tests your thinking over 30+ minutes - Preuve is a one-shot market scan, not founder coaching
