CrowdProof vs Aaru
Aaru is the enterprise heavyweight of decision prediction. CrowdProof is a self-serve social simulation you can start today. Buy one simulation for $29. This page is for anyone deciding whether their question needs a $1B prediction engine or a running crowd. A pending, finished, failed, or stopped run is not live.
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 on the platforms the plan allows (1 on Free, 3 on Pro, all 5 on Team and Enterprise). On a running crowd, you see how opinion spreads and which arguments win. Posts can go viral after engagement spikes. A pending, finished, failed, or stopped run is not live. It is not just what people will think.
- You can start today. Buy one CrowdProof simulation for $29: 500 people, 20 rounds, 3 platforms. Monthly plans stay at $39, $99, and $249. 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: an owner can score a completed run against a survey or shares they already have, and unscored runs stay unscored. The public accuracy page names survey alignment and known-outcome backtests. Unscored runs stay unscored, and a 12-case known-outcome backtest method that reports a hit rate only once enough cases are scored.
- A running crowd. A running crowd streams in God Mode. You can inject events while it is running. A finished share is the report.
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 on 1 to 5 platforms by plan | Enterprise prediction engine (product: Lumen) for simulating decisions |
| How respondents behave | On a running crowd, agents argue and form camps. Posts can go viral after engagement spikes. A pending, finished, failed, or stopped run is not live. | Decision prediction; not a social interaction simulation |
| Accuracy story | Survey alignment and known-outcome backtests. Unscored runs stay unscored | EY replicated its Global Wealth Report overnight with Aaru and reported 90%+ median correlation |
| Credibility signals | An owner can score a completed run against a survey or shares they already have. Only published case studies and scored survey alignment and known-outcome backtests on /accuracy are public. Unscored runs stay unscored | $1B valuation Series A (Dec 2025); Accenture invested |
| Pricing | Public: $29 one run, then free / $39 / $99 / $249 per month | No public pricing; sales-led |
| Time to first result | Self-serve; buy one simulation for $29 | Enterprise sales cycle |
