Unlike ChatGPT-based validators that generate opinions from training data, Preuve AI retrieves real data from Crunchbase, Google Trends, Reddit, Product Hunt, G2, and 35+ other sources - then links every claim to its origin. Over 5,000+ startup ideas have been analyzed across 13 industries since 2026. The median viability score is 55 out of 100, and only 18.3% of ideas earn a go verdict at 70 or above.

The entrepreneurs who survive validate first.
You have an idea. ChatGPT will tell you it's brilliant. Friends will be polite. Six months in, you'll discover what the market already knew.
Preuve scans 50+ live sources in under a minute. 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's 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.
“The products that worked found the problems early. The ones that flopped had blind spots nobody caught.”
