IdeaProof review (2026)
IdeaProof tries everything. Masters none.
IdeaProof tries to validate ideas, then piles on brand, logo, and ad tools, citing barely any sources. Preuve AI does one job: it scans 60+ live sources and ties every claim to its origin.

The core difference
The fundamental difference: where does the data come from?
Preuve AI
Live source scanning
- 10 agents across 7 model families search 60+ sources in parallel
- Cross-validation runs against live data, not against other models
- Competitors found on Crunchbase with real funding data
- Demand signals pulled from Reddit, forums, and review sites
- Every data point links back to its source
- Click any claim to verify it yourself
IdeaProof
LLM-generated analysis
- Multi-model LLM analysis with only a handful of sources cited
- Competitor teardown generated, sources not linked per claim
- Claims "89% accuracy" from a 12-month survival stat, without cohort dates or sample size
- Methodology page says "60+ sources", the homepage says 50+
- A few inline citations; most claims have no clickable source
- Looks thorough, but most numbers have no traceable source
The real test
Does the tool ever say no?
A validator that tells every founder their idea is great is not validating anything, just flattering them.
Preuve AI · 6,000+ ideas
54
median score
6 scoring frameworks against 60+ live sources. Only 17.5% of ideas earn a go verdict. If your idea scores well, it earned it.

Fair assessment
What IdeaProof does well
IdeaProof has strengths worth acknowledging.
All-in-one breadth
One place for validation, market analysis, a business plan, brand strategy, an AI logo, and ad creatives. If you want a bundle, the bundle is real.
Brand and ad assets
Generates a logo, visual identity, and ad creatives for Meta, Google, and TikTok at the Builder and Founder packs. Useful if you need early branding fast.
One-time, no subscription
Pricing is one-time credit packs (EUR 19.99 to 99.99) with no recurring monthly bill.
What Preuve AI does differently
Live source scanning
60+ sources searched in real-time, not from training data. Crunchbase, Google Trends, Reddit, Product Hunt, G2, and more.
Verifiable claims
Click any data point to see its source. No trust required. Every competitor, funding round, and demand signal links back to where we found it.
Honest scoring
We tell founders when their idea needs work. Only 17.5% of ideas earn a go verdict. Six scoring frameworks run against live data, so the score reflects what the market says, not what sounds good.
Investor-ready deliverables
$499 package with pitch deck, investment memo, 18-month financial model, and competitive teardown. Built for due diligence, not just brainstorming.
Interactive dashboard
Shareable link with 21 interactive sections. Filter competitors, drill into market data, and share specific sections with co-founders or investors.
Competitor intelligence
Real competitors with real funding data, real pricing, and real traction. Not a list of names from an LLM's training data.
Business Plan PDF
Defendable 4-6 page Business Plan PDF, bank-ready. Auto-filled from your analysis, share with your cofounder or team in one click.
Claims vs receipts
Same script. Different receipts.
IdeaProof now says what we say, live sources, multiple models, re-runs you can trigger again. Copying the line is easy. Backing it is the part that does not fit in a screenshot.
ClaimsWhat IdeaProof advertisesWhat we actually found
Sources
Their homepage says 50+. Their sample report links 28 pages.
Accuracy
A 12-month survival stat. Which cohort, what counts as survival, how many ideas: not stated.
Social proof
0 reviews on Trustpilot, G2, and Capterra, checked 24 September 2026.
Scale
Read 24 September 2026; the counter has moved since. Their methodology page said 27,000+. Their pricing page said 10,000+ founders. Same product, same week.
Free tier
Accurate at 40 credits, but 10 short of one Market Analysis.
Lock-in
"Credits never expire"
True since their Terms v2.4 (17 Oct 2026). Until then, the Terms said 12 months while the pricing page said never.
Refunds
"All sales are final" on the same page. Their Terms refund a pack only if not one credit was used. Preuve reports carry a 14-day satisfaction guarantee.
Anyone can copy the words. We will show you the links: every claim in a Preuve report ties back to one of 60+ live sources.

Fact-checking IdeaProof's marketing claims
Method missing
"12-month survival tracking"
Our finding
Their methodology page says 89% of ideas scoring 75+ are "still operating" after 12 months, and 67% go on to earn $10,000 a month. It never says which ideas were tracked, how "still operating" was checked, or how many ideas the 89% covers. It never asks what you earn. The quarterly accuracy report it promises does not exist. On 11 October 2026 its llms.txt downgraded the line to "89% internal match rate (internal metric, not certified accuracy)". Its pages still say 89% accuracy. Checked 10 August and 11 October 2026.
Contradicted
"Real-time data · 60+ authoritative sources"
Our finding
Their site markets "real-time data", their methodology page says "60+ authoritative sources" and their homepage says 50+. Their public sample report links 28 outside pages, mostly Reddit threads and competitor sites (checked 24 September 2026). A Preuve report cites 40+ distinct domains, median 70 clickable links. An unlinked number is not one you can verify.
No method
"$2.3M+ raised · 156+ launches · 67% better pitches"
Our finding
Their homepage cites "$2.3M+ in funding raised," "156+ successful business launches," and a "67% improvement in pitch success rates." None of these come with a sample size, time window, or attribution showing the tool caused the outcome. Round numbers without a method behind them are marketing copy.
Contradicted
"10,000+ verified entrepreneurs"
Our finding
IdeaProof went from "2,800+ founders" on Product Hunt (28 January 2026) to "10,000+ verified entrepreneurs" today. On 10 August 2026 we checked third-party review platforms: 0 reviews on Trustpilot, 0 on G2, 0 on Capterra, and 3 on Product Hunt, each from a single-review account. A 10,000+ count with zero third-party reviews behind it is not social proof, it is highly suspicious. Their homepage now shows an even bigger number. See the next card for where it comes from.
Check the links
"Join 110,524+ founders who validated first"
Our finding
That line sat on their homepage next to "110,524+ Ideas Validated" (read 24 September 2026; the counter has moved since). Both come from one function in their code, useValidationCount, which counts rows in their idea_analysis table. So the "founders" figure counts analyses, not people. The same page says "10,000+ verified entrepreneurs".
Its rating markup, the part search engines read, gives the product 4.8 from 10,000 ratings, and also 4.8 from 365, both already there on 11 May 2026 (Wayback copy). The same markup holds 34 reviews under 27 names, among them "Raj Patel, VC Partner, Sequoia India". Their public G2 page showed 0 reviews on 10 August 2026. Every link is theirs.
Same test on us. Preuve has 17 reviews: 10 on Trustpilot, 4 on TheresAnAIForThat, 1 on Product Hunt, 2 sent to us directly, 3 verified purchases. Each one is named on our reviews page. Count them.
Two scores
"3.4 / 5 · reviewed by IdeaProof editorial"
Our finding
IdeaProof publishes two different ratings of Preuve AI, on two of its own pages, both live on 10 August 2026. On their roundup of 8 validators we score 4.6, ranked second and labelled "Best for Evidence-Based Validation". On the page written to rank against our name, the same editorial team scores us 3.4. Their own score does not move between the two: 4.9 on both. A validation tool sells one thing, that a score means something. This one moved 1.2 points depending on which page it sat on.
The real math
What does one report actually cost?
IdeaProof prices in credits, and the credits hide the real cost. Its pricing page puts a validation at 40 credits, but the analysis founders actually want, Market Analysis, at 50, and it gates the Business Plan (100), Brand Strategy (50), Visual Identity (150) and Marketing Suite (250) behind it. One idea taken end to end runs 640 credits. The free tier is 40 credits, which their pricing page describes as one full validation, and which falls 10 short of unlocking a single Market Analysis. On its own, the "EUR 19.99" Starter pack (150 credits) covers a validation, a Market Analysis and a Brand Strategy (140 credits), then stops before the Business Plan (100). With Preuve AI there is no math: $59 for the full report, or run the free scan first.
Our verdict on IdeaProof
2/ 5
IdeaProof, reviewed by Preuve AI, checked 10 August 2026 and rechecked 24 September 2026. The product ships a lot. What pulls the score to 2 is the evidence behind its own claims, every item above verifiable from its own pages. Scale 1 to 5. We are the competitor here, so check the links rather than the number.
Their page about us
Corrections to IdeaProof's "Preuve AI review"
IdeaProof publishes a page about Preuve AI, stamped "Updated November 2026". We read it on 15 October 2026 (archived copy). Four of its claims about Preuve are false. Judge the rest of their page by that. Each one below, with the fact and a link you can open.
False
"No business plan"
The fact
Every Founder Report includes a Business Plan PDF, 4 to 6 pages, bank-ready, listed on our facts page. It has since 11 May 2026: our homepage carried "bank-ready" that week (Wayback, 13 May 2026). In the archived copies of their homepage and pricing page we checked, April to October 2026, the phrase "bank-ready" never appears. It appears on their page dated November.
False
"English-only output"
The fact
The app and its reports run in 8 languages: English, French, Spanish, German, Portuguese, Italian, Arabic and Korean. The switcher sits in the app header, and the landing exists in each one, for example in French.
False
"One report per $59, no reusability across pivots"
The fact
A Founder Report ships 3 ranked pivots, lets you edit the idea and re-run it without buying a new report, and includes unlimited Starter Scans. The list is on our facts page.
Wrong number
"18.3% pass rate, no published methodology"
The fact
The figure is 17.5%: the go rate across 6,000+ analyses in our July 2026 benchmark, with the method and the full score distribution published in the benchmark post. Their page also puts our source count at 50+. It is 60+.
Their math
"€99 vs $558"
The fact
Three things their price table skips. Their €19.99 pack stops before the business plan: 150 credits, the plan costs 100 once validation and market analysis took 90. One full idea is €49.99 on their credit table, €99.99 on their own "real math". Preuve's $59 includes the business plan PDF. The $558 adds our $499 Investor Package: a pitch deck and investment memo the founder builds by hand from your report, 2+ hours of work. No credit pack produces that.
Verdict in one minute
Who should use which tool
IdeaProof stretches across validation, branding, logos, and ad creatives. That breadth is the pitch, but a tool doing six jobs rarely goes as deep on any one as a tool built for a single decision. It works best when bundled brand assets matter more than proof. Preuve AI is the better call once you need validation that holds up when a real decision rides on it.
Pricing, founder feedback, and where Preuve falls short are in the Preuve AI review.

FAQ
Common questions about Preuve AI vs IdeaProof
Is IdeaProof legit?
IdeaProof is a real product: you can sign up, use 40 free credits (one validation) and buy credit packs from €19.99 to €99.99. What does not hold up is its social proof. Its homepage line "Join 110,524+ founders who validated first" came from the same counter as its "110,524+ Ideas Validated" (read 24 September 2026; the counter has moved since), and that counter counts analyses, not people. Its rating markup gives the same product 4.8 from 10,000 ratings and 4.8 from 365 ratings, both already in an 11 May 2026 archive copy. No third-party reviews back any of it: 0 on Trustpilot, G2 and Capterra. Reviews checked 24 September 2026, pricing 9 October 2026. So the product is real, and its numbers need checking before you trust them.
Is IdeaProof accurate?
IdeaProof advertises "89% prediction accuracy" next to "10,000+ founders". It does publish a research methodology page, so the number is not unexplained. The problem is what that page leaves out. It says 89% of ideas scoring 75+ are "still operating" after 12 months, but not which cohort was tracked (the validation dates), how "still operating" was checked, or how many ideas the figure covers. Without those three, nobody outside IdeaProof can check the 89%. It says 67% of high-scoring ideas go on to earn $10,000 a month, a revenue figure it never collects. It says it publishes an accuracy report every three months. There is none. Checked 10 August 2026. Preuve AI claims no accuracy number at all: every data point links to its source, so you check it yourself.
Which tool gives real market data?
Preuve AI pulls from 60+ live sources (Crunchbase, Google Trends, Reddit, Product Hunt, G2) and links every claim to its origin. IdeaProof runs a multi-model setup and links some sources: its public sample report links 28 outside pages, mostly Reddit threads and competitor sites (checked 24 September 2026). Before a funding decision depends on the numbers, check which claims carry a link.
Can I try both tools for free?
Yes. Preuve AI offers a free viability scan (score + risks + 2 competitor previews). IdeaProof gives 40 free credits, which its pricing page describes as one full validation. The deeper Market Analysis (50 credits) sits just past the free tier. Try both and compare the outputs.
What is the best startup validation tool in 2026?
It depends on what you need. If you want a verdict where every claim links to the page it came from, Preuve AI is built for that. If you want brand identity and marketing assets bundled with validation, IdeaProof covers that at higher tiers.
Does IdeaProof offer investor packages?
As of July 2026, IdeaProof's paid tiers generate an investor-ready business plan with financial projections, and a 10-slide investor deck is available as a credit add-on, both AI-generated. What it does not sell is a done-for-you package. Preuve AI's $499 Investor Package is founder-built and reviewed from your own report: pitch deck, investment memo, 18-month financial model, and competitive teardown.
