Stephane Fourdrinier shares how a personal health wake-up in 2017 (and an 80-pound transformation) led him to build Track Our Heart, an ambitious biometrics platform that fuses data from rings, watches, chest straps, ECG patches, oximeters, foot pods, muscle oxygen sensors, headbands (and more) into one coherent, user-tailored view.
We dig into: why today’s device ecosystems are siloed, unlocking beat-to-beat heart data 24/7, estimating blood pressure through multi-sensor fusion, supporting three distinct personas (longevity & general wellness, cardiac monitoring, and high-performance athletes), designing for both casual and advanced “data power users,” remote monitoring for aging parents, correlating meals, timing, alcohol, HRV breathing, and sleep, community-driven anonymized insight sharing, and his $2M seed raise (engineering, UX, community).
Stephane outlines a roadmap toward 180+ biometrics, exportability, Kickstarter considerations, and how multi-sensor synchronization unlocks richer preventative and performance insights.
