Opinions vs proof
Preuve AI turns your startup idea into source-linked evidence instead of generic validator opinions.
We ran the same idea through a typical AI validator (knowledge cutoff Oct 2024, score: 82, 0 source links) and Preuve AI (live May 2026, score: 54, 23 source links from Crunchbase, Reddit, and Gartner). The lower score came with verifiable evidence.

Scoring Philosophy
Most tools inflate scores to feel encouraging. We don't, because a lower number with real evidence beats a high one without it.
~78
average score
Scores cluster in the 74-85 range because almost every idea passes. When everything passes, the number stops meaning anything.
~55
median score
Cross-checked against live data and what competitors are actually charging. Only 18.3% earn a Go, which is what makes the verdict mean something.
A 54 here points at specific weaknesses you can address. An 82 from a cheerleader tool points at nothing.
Pulls from 50+ live sources including Crunchbase, Product Hunt, Reddit, and news feeds, not a frozen snapshot from a training cutoff.
Every data point links back to where it came from, so you can check any claim before putting it in front of investors.
Goes beyond a list of names: each competitor comes with funding, pricing, and traction data.
Bottom-up market sizing that shows its working. Ready to paste into an investor deck.
Spots underserved angles in the market and suggests concrete pivots backed by sourced reasoning.
Pitch deck, investment memo, financial model, competitive teardown, and due diligence report.
