Client Stories

What Fitness Founders & CTOs Say About Us

Real outcomes from real partners across workout, wellness, and gym-management apps.

Brilworks shipped our workout app MVP in 14 weeks with Apple Watch sync and streak-based retention built in. We hit 52% D30 retention in month two — 3x our category benchmark.

They pushed back on features that looked pretty but wouldn't move retention, and championed the ones that did. Our D30 numbers are the highest our investors have ever seen in the wellness space.

Jordan LeeProduct Lead, Wellness App

We needed Apple Health, Google Fit, Garmin and Fitbit sync in one codebase. Brilworks delivered it without the flakiness we'd seen from three prior vendors. HIPAA-ready infra was a bonus.
