Preuve AI vs IdeaProof
Both tools validate startup ideas with AI. The difference is where the data comes from and whether you can verify it.
TL;DR: Preuve AI scans 40+ live sources and links every claim to its origin. IdeaProof generates analysis from LLM models without external source verification.

Feature comparison at a glance
| Feature | Preuve AI | IdeaProof |
|---|---|---|
| Data sources | 40+ live sources (Crunchbase, Trends, Reddit, PH, G2) | AI-generated (Claude 3.5 + GPT-4, both from 2024) |
| AI models | 7 model families in parallel (Gemini, Claude, GPT, Grok + Exa retrieval) | Claude 3.5 + GPT-4 (released 2024) |
| Source linking | Every claim links to its origin | No source links |
| Report sections | 13 interactive sections | 10 sections, 20+ pages |
| Pricing model | $29 one-time per report | Credit-based from EUR 19 |
| Free tier | Free viability scan | 70 free credits (~2 validations) |
| Scoring approach | 6 frameworks, median score ~50. No accuracy claim - every source linked for you to verify. | Claims "89% accuracy" with no methodology, no benchmark, no definition of what "accuracy" means for startup validation. |
| Score reliability | Verdict cross-checked by multiple AI runs, we auto-rerun when they disagree. | Single AI run, no cross-check. Score can drift if you re-run the same idea. |
| Investor package | $499 (pitch deck, memo, financial model) | Not available |
| Output format | Interactive dashboard + shareable link | PDF export |
| Competitor mapping | Live data with funding, pricing, traction | AI-generated list |
| TAM/SAM/SOM | Bottom-up with sources | Included (methodology unclear) |
| Pivot recommendations | Yes, based on competitive gaps | Not available |
| Brand / visual identity | Not included | Included in Builder tier (EUR 49) |
The fundamental difference: where does the data come from?
Preuve AI
- 10 agents across 7 model families search 40+ sources in parallel
- Models cross-validate against live data, not against each other
- Competitors found on Crunchbase with real funding data
- Demand signals from Reddit, forums, review sites
- Every data point links back to its source
- You can click any claim and verify it yourself
IdeaProof
- Runs 4 LLMs and merges their outputs
- Competitor data comes from model training data
- Claims "89% accuracy" - no methodology, no benchmark, no ground truth defined
- No source links - claims are unverifiable
- Cross-validates models against each other, not against live data
- Looks comprehensive but can't be fact-checked
Common questions about Preuve AI vs IdeaProof
Is IdeaProof accurate?
IdeaProof claims 89% accuracy 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 40+ 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. The distinction matters when you need to trust the numbers.
Can I try both tools for free?
Yes. Preuve AI offers a free viability scan (score + risks + 2 competitor previews). IdeaProof offers 70 free credits (approximately 2 validations). 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 offers that at higher tiers.
