Is Preuve AI Legit? An Honest Founder Answer

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. Here is the honest version of who runs this, what the proof is, what happens to your idea, and how to confirm all of it yourself.

What is Preuve AI, exactly?

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 whole point is to tell you something you would rather not hear while it is still cheap to change your mind.

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. You can see the full method on the sources page and the product story on the about page.

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.

This matters for the legitimacy question more than it looks. 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, and the useful way to answer that 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:

Preuve fails the scam test on every line, which is the point of listing them. You are not meant to take that on faith either. Every item above is something you can confirm from the outside before you spend a dollar.

What proof is there that it works?

I would rather give you numbers than adjectives here. Start with the reviews: a 4.8 out of 5 across 12 reviews, sourced from Trustpilot, Product Hunt, There's An AI For That, and direct messages from founders. You can read them on the reviews page, which links straight to the Trustpilot profile so you are not stuck reading testimonials I picked.

Then the scale. Preuve has analyzed 5,500+ startup ideas across 13 industries, and a source-family audit of 246 recent paid reports counted 6,000+ sources cited. I track those because they show whether the sourcing is actually holding up, not to decorate a landing page.

The number I care about most is the calibration. Across that corpus the median viability score is 55 out of 100, and only 18.3% of ideas earn a launch-ready verdict of 70 or higher. Most AI validators cluster their 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. I broke down the full distribution in my 2026 validation benchmarks.

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 50+ 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 itself 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 breakdown, including the recurring publications the agents read, lives on the sources page. 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. I cannot read your submissions to score them, and I do not. 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 the infrastructure side: 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 (Supabase and Vercel), and row-level security means 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 full detail is on the security page.

What does it cost, and is there a refund?

The honest pricing, no dark patterns. The Reality Check is free and needs no card. The Founder Report is a $29 one-time purchase for the full 15-section analysis. There are multi-report packs at $95 and $159, a $499 Investor Package, a $19/month Radar Pro subscription for ongoing monitoring, and lifetime plans at $499 and $999. You can see all of it on the pricing page.

On refunds I will be straight, because this is where trust is won or lost. Eligible report purchases, including Founder Reports, may be covered by a limited 14-day report guarantee, and 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 to you.

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. Here are four ways to confirm the whole thing from the outside, fastest first:

Where these numbers come from

I am not going to tell you to verify everything and then hide the receipts. Here is where each claim on this page lives, so you can check it without my help:

• The 4.8/5 across 12 reviews: the reviews page and the Trustpilot profile.
• The 50+ live sources, the 6,000+ citations, the 18.3% launch-ready rate, and the six-factor method: the sources page.
• The no-human-reads-it claim, the encryption, and the GDPR handling: the security page.
• Every price and the 14-day report guarantee: pricing and the 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 are worth saying out loud too. It is run by one person, so it does not have the support bench of a funded company. It is young, and 12 public reviews is a real number but a small one 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. The fastest way to decide is to run your idea through a free scan and judge the proof yourself.
