The Challenge

Coaching quality doesn't scale by hand. Every plan was written by hand, every Sunday, and coaches were capped at roughly forty clients each before quality — and their own hours — broke down.

The Strategy

The data needed to write a good plan was already on the client's wrist. Nobody was using it. If a model could draft the plan from real activity data, the coach could stay the author instead of the author of every single word.

The Solution
Product

A client app plus a coach console sharing one training model — sessions, load and readiness in one place.

AI & tech

Weekly plans drafted automatically from wearable and session data; the coach approves, edits or overrides in one screen. Adaptive programming responds to fatigue signals mid-week, not just at the next check-in.

Marketing & growth

Creator-led acquisition, followed by a 14-day activation sequence keyed to the client's first logged workout.

Process

Discovery interviews with coaches and clients surfaced the real bottleneck — plan-writing time, not client demand. We validated the AI-drafted plan concept with a clickable prototype before committing to the build, then shipped the coach console and client app in parallel two-week increments.
