# Revenue Bench

> Revenue Bench measures the data vendors and AI models that GTM teams buy, on real records, and publishes the aggregates. It is run by Cheetah. We test vendors on records where we already knew the right answer, and we keep those answers private.

Every score has a likely range (a 95% interval). Vendors that a paired test cannot separate from the leader share the top tier. Accuracy, cost and speed are reported on separate axes. The site publishes aggregates only, with no names, emails or row-level records.

## Reports

- [Contact Data, Nov 2026](https://revenuebench.com/benchmarks/contact-data/): We tested 83 contact-data vendors on four jobs, on records where we already knew the right answer. Email verification, work email finding, job change detection and people search.
- [AI judges for data hygiene, Nov 2026](https://revenuebench.com/benchmarks/ai-judges/): We tested 34 AI models on four CRM clean-up jobs, using a B2B SaaS company's outbound and CRM records where we already knew the right answer. Duplicate records, own work email, same person and main employer.
