The verification layer for athletic loyalty

Effort verified.

PROOF Verified Effort™

One badge.
Every sport.

PROOF Verified Effort is a universal trust mark that confirms real athletic activity — verified through GPS, heart rate, and platform APIs. It works across every sport, every unit, every brand.

Integration

Three steps.
One API.

PROOF sits between your customers' fitness platforms and your loyalty engine. One integration, every sport.

01
Connect
Add the PROOF SDK to your stack. We handle OAuth for Strava, Garmin, Apple Health, Peloton, Whoop, and 30+ platforms. Your customer connects in one tap.
02
Verify
Every activity runs through our verification pipeline — GPS validation, anomaly detection, cross-referencing. Fraudulent data gets flagged. Clean data gets the PROOF Verified Effort badge.
03
Reward
Verified effort flows into your loyalty system — LoyaltyLion, Yotpo, Smile.io, or custom. You define the rules. One mile, one rep, one session — whatever fits your brand.
Developer-first
