Aaru alternatives
Aaru publishes one specific accuracy result on its site: a 0.90 median Spearman correlation on a blinded recreation of EY's 2025 Global Wealth Study. It does not publish a pooled public-poll MAE or a price list. Alternatives should be scored on whether they publish an equally scoped number, a different unit, or nothing.
What you are actually replacing
Aaru's public pages describe simulated populations for product, price, message, segmentation, scenario planning, and communications. The EY study is a wealth-research recreation, not a grocery message test. If your use case is a U.S. consumer panel with crosstabs, you are not buying the EY artifact. Ask every vendor for a number on your instrument class.
Worked example: do not convert the EY number
A 0.90 Spearman on 3,600 affluent investors across 30+ markets tells you ranks moved together on that study. Lewsearch's 7.47% MAE on 404 public-poll items tells you the average option-share gap on a different set of questions. Simile's 7,000 weekly evaluations tell you evaluation cadence, not option-share error. A serious shortlist keeps all three in their own units and asks for the raw table.
If the decision is a U.S. state panel you can re-run yourself, Lewsearch publishes Texas at 4.88% and California at 7.77%, with coverage on coverage (27 live panels · U.S. national · 4 census regions (32 audiences)). That file is on methodology. Current commercial terms are on pricing.

FAQ
- What does Aaru publish that alternatives must match?
- A scoped correlation: median Spearman 0.90 on a blinded recreation of EY's 2025 Global Wealth Study (3,600 investors, 30+ markets, one day). Alternatives should be asked for an equally specific instrument, n, and holdout rule.
- Does Simile publish the same kind of number?
- No. Simile publishes weekly evaluation volume (over 7,000) and academic citations. It does not publish a Spearman on the EY wealth study, and it does not publish a pooled public-poll MAE.
- Is there a self-serve Aaru alternative?
- Lewsearch is self-serve and publishes pricing. Synthetic Users publishes per-interview prices. Aaru and Simile do not publish price lists on their homepages.
- Can I treat 0.90 Spearman as 90% accuracy?
- No. Spearman correlation is not percent correct and is not mean absolute error.
