Story
Goal
Build a sticky, science‑backed wellness companion that would:
- Hit ≥ 1 M daily active users inside Year 1.
- Triple 30‑day retention—industry median sits at just 3–8 %.
- Lift session length ≥ 7 min and push‑opt‑in engagement ≥ 60 %.
- Monetize via freemium PLUS brand‑safe wellness marketplace.
Challenge
The wellness market is punishingly competitive—retention is brutal and user fatigue kills growth:
- Retention cliff—day‑30 usage often ≤ 8 %.
- Notification fatigue—46 pushes/day is the U.S. norm.
- Content churn—1.4 M SKUs across workouts, meditations, nutrition.
- Data privacy—HIPAA‑adjacent biometrics + GDPR.
- Global scaling—10 languages, 5 payment rails.
- Wearable fragmentation—Apple, Fitbit, Garmin, Oura.
