Imperfect

Imperfect (Imperfect Wellness, Inc.) is a San Francisco-based, Y Combinator-backed (Spring 2026) consumer startup building an adaptive AI training coach for endurance athletes across cycling, trail running, swimming, and other sports. The mobile app connects to a user's wearables and health apps to generate real-time training, recovery, and nutrition recommendations that adapt to how the athlete's body is actually responding day to day, rather than following a static plan written weeks in advance. Founded by Matin Tamizi (previously built and sold two fintech companies and authored a widely used open-source Garmin library used by Stanford Health). Imperfect ships as a consumer mobile application (Google Play) and publishes no public developer API, SDK, or developer portal at this time.

Imperfect is profiled on the APIs.io network. Tagged areas include Company, Health, Fitness, Wellness, and Sports.

Imperfect’s developer surface includes engineering blog, signup flow, support, and 4 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
