CrowdProof vs Aaru
Aaru is the enterprise heavyweight of decision prediction. CrowdProof is a self-serve social simulation you can run today for free. This page is for anyone deciding whether their question needs a $1B prediction engine or a live crowd.
What Aaru does well
Aaru (aaru.com, tagline "Simulate any decision") sells an enterprise prediction engine, productized as Lumen, for simulating how populations decide. Its flagship proof point is hard to argue with: EY replicated its annual Global Wealth Report overnight with Aaru and reported 90%+ median correlation with the original human research. Accenture invested, and the company raised a Series A at a $1B valuation in December 2025. This is the credibility tier that closes Fortune 500 deals.
Choose Aaru if you are an enterprise replacing large-scale primary research, you need a vendor your consulting partners already trust, and a sales-led engagement with no public pricing fits how you buy. For replicating survey-scale research programs, Aaru's EY result is the strongest single benchmark in the category.
Where CrowdProof differs
- A different question. Aaru predicts decisions; CrowdProof simulates the conversation that produces them. Up to 5,000 simulated people react to each other across five simulated social platforms, so you see not just what people will think but how opinion spreads, which arguments win, and what goes viral.
- You can start today. CrowdProof is self-serve from free, with public pricing at $39, $99, and $249 per month, by far the lowest published pricing in the category. Aaru has no public pricing and sells through an enterprise sales motion.
- Verification you can inspect. Aaru's 90%+ correlation comes from a marquee EY engagement. CrowdProof publishes its accuracy in the open: every simulation can be validated against real people via a built-in survey link, the public accuracy page shows the live average alignment with a 95% confidence interval, and a backtest scores the engine against 12 famous historical launches with a majority-class base rate for comparison.
- Live observability. CrowdProof runs stream in real time and support mid-run event injection, useful for crisis rehearsal and message testing where the sequence of reactions matters.
Honest trade-offs the other way: Aaru operates at a scale and credibility tier CrowdProof does not claim. CrowdProof is newer, has a smaller validation corpus, no independent Big Four audit, and no census-calibrated persona base. If your use case is replicating a global research report for an enterprise client, Aaru is built for exactly that.
| CrowdProof | Aaru | |
|---|---|---|
| Core method | Simulated crowds of up to 5,000 people interacting across 5 social platforms | Enterprise prediction engine (product: Lumen) for simulating decisions |
| How respondents behave | Agents react to each other: argue, form camps, go viral | Decision prediction; not a social interaction simulation |
| Accuracy story | Live public alignment average with a 95% CI, plus a 12-launch backtest vs a majority-class base rate | EY replicated its Global Wealth Report overnight with Aaru and reported 90%+ median correlation |
| Credibility signals | Per-run validation against real people; everything published openly | $1B valuation Series A (Dec 2025); Accenture invested |
| Pricing | Public: free, $39 / $99 / $249 per month | No public pricing; sales-led |
| Time to first result | Self-serve; run a free simulation today | Enterprise sales cycle |
