An Honest Founder Answer (2026) Yes, Preuve AI is legit. It is a real startup idea validation tool that one named, solo founder builds and runs, and you can check that claim in about a minute without paying anything. I am that founder, so treat this as a biased source and verify everything. The difference with Preuve is that you actually can. Every number in a report links to a live source, the reviews link out to third-party platforms, and the free scan runs with no card.

Preuve AI is an AI tool that scores whether a startup idea is worth building. You describe your idea, and it returns a 0 to 100 viability score with a verdict, the market size, the real competitors, demand signals, and the risks that would kill it. The category is idea validation, the step that comes before you write code or spend money. It does not write your business plan or role-play a chatbot conversation. The difference from asking ChatGPT is sourcing. A general chatbot will hand you a market size and a competitor list with total confidence, whether or not it made them up. I built Preuve so that every claim links back to where it came from, which means you can audit the verdict instead of trusting it. The full method is on the sources page (https://preuve.ai/sources) and the product story is on the about page (https://preuve.ai/about). ## Who is behind Preuve AI? I am Vincent, the solo founder. I built Preuve after watching too many startups fail from blind spots nobody caught in time. I am not hiding behind a logo or a fake team page: I build Preuve in public under my own name, so you can follow the work, and the mistakes, as they happen. I put my name on it because that is the only real accountability a solo product has: if a report is wrong, you know exactly who built it. That cuts the other way too, and I would rather say it now than have you find out later. I am one person, so the support bench is smaller than a funded company's, and the bus-factor risk is real. ## Is Preuve AI a scam? No. The useful way to answer is to define the word. A scam hides who runs it, fakes its proof, takes your money before you can judge the quality, and makes leaving hard. Run Preuve against that checklist: - **Who runs it is public.** A named founder who builds in public, not an anonymous brand. - **The proof links out.** Reviews point to Trustpilot, Product Hunt and There's An AI For That, not just to Preuve's own page. - **You judge before you pay.** The free Reality Check returns a real score and verdict with no credit card. - **Leaving is easy.** Eligible reports carry a 14-day guarantee, and a delete-account request purges your data. Preuve fails the scam test on every line, and every item is something you can confirm from the outside before you spend a dollar. ## What proof is there that it works? Three kinds of evidence, with numbers rather than adjectives. 1. **Reviews:** 13 verified 5-star reviews, sourced from Trustpilot, Product Hunt, There's An AI For That, and direct messages. They are on the reviews page (https://preuve.ai/reviews), which links straight to the Trustpilot profile (https://www.trustpilot.com/review/preuve.ai). It is a small, young number, and I am growing it the slow, honest way. 2. **Scale:** Preuve has analyzed 7,000+ startup ideas across 13 industries, and a source-family audit of 410 recent paid reports counted 7,300+ distinct source URLs. 3. **Calibration:** across that corpus the median viability score is 54 out of 100, and only 17.5% of ideas earn a launch-ready verdict of 70 or higher. Most AI validators cluster scores at 75 to 85, since a flattered founder is likelier to pay, and a tool that scores almost everything as great is not really validating anything. Full distribution: https://preuve.ai/blog/startup-validation-benchmarks-2026 ## How does Preuve actually produce a verdict? Under the hood it is an agentic RAG pipeline, not a single ChatGPT prompt. Ten AI agents search the live web in parallel and pull real evidence from 60+ live data sources across families like funding databases, review sites, and community forums. The verdict is the convergence point of those runs, and when two runs disagree the analysis reruns until two models agree. The score is a 0 to 100 rating built from six factors: how big the market is and whether it is growing, real demand signals, how crowded the space is, whether the moat holds, whether the business model actually closes, and the regulatory or execution risk. Market sizing uses a bottom-up TAM, SAM and SOM tied back to market-research and funding sources. The full methodology, what each factor measures and how to read the score, is published on the how it works page (https://preuve.ai/how-it-works), and the recurring publications the agents read live on the sources page (https://preuve.ai/sources). Reproducibility is the design goal: you can click any number in a report and land on the source it came from. ## Is my idea safe with Preuve AI? Your idea never crosses a human inbox, dashboard, or screen. Preuve is a solo company with no employees, and your idea is researched and scored entirely by AI. No human reads your idea. The one exception is opt-in and paid: if you buy the $499 Investor Package, you are explicitly hiring me to build your pitch deck and memo from your own report. On infrastructure: sign-in is passwordless magic-link or OTP, so there are no passwords to leak because none are collected. Data is encrypted with TLS 1.3 in transit and AES-256 at rest, runs on SOC 2 Type II infrastructure (Cloudflare and Vercel), and every query is scoped server-side to your account so users can only reach their own data. The AI providers operate under enterprise terms that prohibit training on your data. Per GDPR, a confirmed breach affecting your data is reported within 72 hours, and the delete-account endpoint purges your data on request.

The Founder Report is a $29 one-time purchase for the full 18-section analysis. There are multi-report packs at $95 and $159, a $499 Investor Package, a $19/month Radar Pro subscription, and lifetime plans at $499 and $999. Full pricing: https://preuve.ai/pricing On refunds: eligible report purchases, including Founder Reports, may be covered by a limited 14-day report guarantee, where the resolution can be account credit, a rerun, troubleshooting, or a cash refund. Other one-time purchases are generally non-refundable once fulfilled, and lifetime plans are non-refundable once provisioned, except where the law requires otherwise. The free tier exists precisely so you can judge the quality before any of that applies. ## How can I verify Preuve AI is legit myself? I am obviously not a neutral source here, so do not take my word for it. Each of these you can run before spending anything: 1. **Read the reviews on Trustpilot,** not on my site: https://www.trustpilot.com/review/preuve.ai 2. **Run the free scan** with no card and judge the output for yourself: https://preuve.ai/ 3. **Click any source in the report.** If a number does not link to something you can open, treat it as wrong, including mine. 4. **Look us up.** Preuve AI has a company page on LinkedIn (https://www.linkedin.com/company/preuve-ai), and I build in public, so there is a real person you can hold accountable. ## Where these numbers come from Every claim on this page is checkable without my help: - The 13 verified 5-star reviews: the reviews page (https://preuve.ai/reviews) and the Trustpilot profile (https://www.trustpilot.com/review/preuve.ai). - The 60+ live sources, the 7,300+ distinct source URLs, the 17.5% launch-ready rate, and the six-factor method: the sources page (https://preuve.ai/sources). - The no-human-reads-it claim, the encryption, and the GDPR handling: the security page (https://preuve.ai/security). - Every price and the 14-day report guarantee: pricing (https://preuve.ai/pricing) and terms (https://preuve.ai/terms). ## My honest verdict Preuve AI is legit. One person runs it openly, the reviews link out to third-party pages, and every number in a report traces back to a source you can open. The honest limits: it is run by one person, so it does not have the support bench of a funded company. It is young, and 13 public reviews is a real but small number that I am growing the slow, honest way. And it validates ideas, it does not build the business for you. If the main thing you want is to hear that your idea is brilliant, I am the wrong product. I built Preuve to give the uncomfortable version, sourced line by line, before you sink six months into the wrong idea. ## FAQ ### Is Preuve AI legit? Yes.
