Sendo

Problem

Most climbers learn by trial and error. Coaching is expensive and rare, so bad habits stick. In a 100-climber survey, 80% said they had no source of feedback on their form.

Users

Recreational climbers who want to progress but don't have regular access to a coach.

My role

Founder & Product Lead. I ran discovery, scoped the MVP, led 1 engineer and 1 designer, and built the MediaPipe pose model myself.

Approach

• Ran 15+ user interviews and a 100-climber survey to find the most painful gap: no form feedback.
• Scoped the MVP down to a single feature, form scoring, instead of a full training app.
• After launch, 20+ surveyed users said raw metrics weren't helpful, so I A/B tested per-move body cues against them.

Solution

A real-time web app that scores a climb from video using pose estimation, then tells the climber what to fix, move by move.

Results

• 40+ beta users logged 400+ climbs (about 10 per user)
• 70% 30-day retention
• 19 of 20 in-app ratings positive
• Per-move body cues took weekly climbs logged from 30 to 70

What I'd do next

Reach beyond active climbers: make Sendo the way people who have never touched the sport take their first climbs, with form guidance from day one.
