What Preuve AI does
You describe a startup or product idea. According to the listing, ten AI agents then research demand, competitors and pricing using more than 60 sources such as Crunchbase, Google Trends, Reddit, Product Hunt and G2. The report links claims to the page they came from, so you can check them yourself.
The founder is a former B2B growth marketer based in Paris. He says the tool is strict on purpose and cites a July 2026 benchmark in which only 17.5% of more than 6,000 anonymized ideas cleared the launch-ready bar. That figure is the vendor’s own and we could not verify it.
Main features
- Viability score out of 100 and a launch-ready bar.
- Up to 15 competitors with funding, pricing and a threat level.
- Smart Pivots: suggested changes with expected gain, effort, trade-off and evidence, which you can apply and have rescored.
- Starter scans to test new angles cheaply before a deep report.
- A build kit with AGENTS.md, a five-milestone PLAN.md and docs on buyers, scope, competitors, pricing and risks, for Claude Code, Cursor, Codex or Antigravity.
- A first-100-customers plan and MCP access.
Pricing on AppSumo (9 November 2026)
| Tier | Price | Deep reports | Starter scans | Smart Pivots | Market alerts |
|---|---|---|---|---|---|
| Tier 1 | $59 | 3 | 25 | 1 | 1 idea |
| Tier 2 | $139 | 10 | 100 | 3 | 2 ideas |
| Tier 3 | $269 | 25 | 200 | 5 | 3 ideas |
| Tier 4 (Agency) | $549 | 80 | Unlimited | 1 per report | None listed |
Tier 4 adds the agency features: client report export, client share controls, white label, a commercial license, an agency workspace and a branded intake form. Our arithmetic: Tier 1 works out to about $19.67 per deep report ($59 divided by 3) and Tier 4 about $6.86 ($549 divided by 80). The listing does not say whether these limits renew or are one-time, so check that before buying.
When we read the page it showed 4 reviews and 47 purchases, a 60-day refund, and it was founded on 26 January 2026. It is bootstrapped with a team of 1 to 10.
Who it fits
- Solo founders who want a structured check before building.
- People using AI coding tools who want research turned into a build plan.
- Agencies that want to sell idea validation (Tier 4).
Who should skip it
- Anyone who already validates with customer interviews and is happy with that.
- Buyers who need proven accuracy. A score from an AI report is an input, not a verdict.
- Those who need unlimited reports on a low tier.
How to test it safely
Run one idea you already know well and compare the report with what you know. Open several of the cited sources to confirm they say what the report claims. Do this within the 60-day refund window.

Bottom line
Preuve AI is a sensible way to pressure-test an idea cheaply, and the cited sources make the output checkable. It is very new and its limits are unclear on renewal, so start with the smallest tier or test hard in the refund window.
