The core difference
The fundamental difference: where does the data come from?
Preuve AI
Live source scanning
- 10 agents across 7 model families search 50+ 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
- Analysis generated by LLMs, no external sources named
- Competitor lists generated, not pulled from live funding data
- Claims "89% accuracy" - no methodology, no benchmark, no ground truth defined
- Claims "real-time data" but names no data sources
- No source links - claims cannot be fact-checked
- Looks thorough, but you cannot trace where any number came from
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.

~55
median score
6 scoring frameworks against 50+ live sources. Only 18.3% of ideas earn a go verdict. If your idea scores well, it earned it.

A low score points to specific problems, most of them fixable. The gap between a 48 and a 72 is usually 2-3 things you can address.
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) and their site states purchased credits never expire. No recurring monthly bill.
What Preuve AI does differently
Live source scanning
50+ 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 18.3% 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 13 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.
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.
Choose Preuve AI if
- You need evidence-backed validation with source links
- You want honest scoring that tells you when to pivot
- If investor-ready deliverables matter, Preuve is the right call
- You want to verify every claim in your report with one click

Choose IdeaProof if
- You want brand identity and visual assets included
- You prefer credit-based pricing in EUR
- You want marketing copy and ad concepts generated
- Source verification isn't critical for your use case
Verify everything
Fact-checking IdeaProof's marketing claims
“89% accuracy · verified with 10,000+ users”
This sits on their homepage and repeats across the site (“89% accuracy · 50+ criteria · Real-time data · 2026 refresh”). We looked for the methodology behind the number. No benchmark dataset, no study, no definition of what “accuracy” means for a startup prediction. If a founder put an unverifiable accuracy stat in a pitch deck, investors would flag it.
“Real-time data · 50+ authoritative sources”
Their site markets “real-time data” and “50+ authoritative sources,” but names none of them and links none of them. The output reads like LLM inference, and there is no clickable trail from any claim to where it came from. Real-time data you cannot inspect is a label, not a source.
“$2.3M+ raised · 156+ launches · 67% better pitches”
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.
“10,000+ verified entrepreneurs”
IdeaProof went from “2,800+ founders” on Product Hunt (June 2025) to “10,000+ verified entrepreneurs” on their homepage (June 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 user count with no independent reviews behind it is a claim, not social proof.
What does one report actually cost?
With IdeaProof you buy credit packs (EUR 19.99 to 99.99) and work backward to the per-report price, and their own free tier is listed as both 70 and 90 credits on different parts of the site. With Preuve AI there is no math: $29 for the report, or run the free scan first.

FAQ
Common questions about Preuve AI vs IdeaProof
Is IdeaProof accurate?
IdeaProof claims "89% accuracy verified with 10,000+ users" but doesn't disclose the methodology, benchmark dataset, or definition of "accuracy" for startup validation. There is no industry-standard ground truth to measure against. Preuve AI takes a different approach: instead of claiming a number, every data point links to its source so you can verify accuracy yourself.
Which tool gives real market data?
Preuve AI pulls from 50+ live sources (Crunchbase, Google Trends, Reddit, Product Hunt, G2) and links every claim to its origin. IdeaProof uses multi-model AI to generate analysis without external data verification. That difference is critical when a real funding decision depends on the numbers.
Can I try both tools for free?
Yes. Preuve AI offers a free viability scan (score + risks + 2 competitor previews). IdeaProof offers a free tier with 3 validations included (their site lists both 70 and 90 free credits). Try both and compare the outputs.
What is the best startup validation tool in 2026?
It depends on what you need. If you want evidence-backed analysis with verifiable source links, Preuve AI is the only tool that delivers this. If you want brand identity and marketing assets bundled with validation, IdeaProof covers that at higher tiers.
Does IdeaProof offer investor packages?
As of June 2026, IdeaProof's top pack (Founder, EUR 99.99 one-time) generates a business plan, but there is no dedicated done-for-you investor package. Preuve AI offers a $499 Investor Package covering pitch deck, investment memo, 18-month financial model, and competitive teardown.
