The benchmark

We checked our work against real A/B test winners.

Benchmarked against completed live A/B tests across ecommerce, SaaS, and fintech flows, including product pages, checkout, pricing, onboarding, and landing pages. Then we compared Squoosh's predicted winner to the live result.

✓Completed tests only: known live winners, not synthetic-only benchmarks.
✓Blind prediction: Squoosh picked a winner before seeing the live result.
✓Controlled comparison: each variant was evaluated under the same modeled buyer conditions.
✓Pre-traffic decision: use the result to decide what deserves live traffic.

Prediction accuracy

Squoosh matched the live winner in 81% of completed A/B tests.
