A coach for every athlete.

Betta is a smart sleeve that teaches perfect form through touch. Built by athletes.

The Problem

Every athlete trains alone.
No one tells them what's wrong.

Feedback comes too late

Video review and smart balls only show mistakes after the fact. The neurological window for correction has already closed.

🔄

Bad reps compound

Without real-time intervention, every solo practice session reinforces the exact habits athletes are trying to break.

💰

Elite coaching costs $100/hr

The athletes who need feedback the most are priced out of getting it. Talent shouldn't have a pay wall.

Three steps. Zero screens.

01 — CALIBRATE

It learns you

Betta's dual motion sensors map your personal best technique. Instead of comparing you to a textbook, it learns your Optimal Form Signature — the version of your shot that's uniquely, measurably yours.

02 — DETECT

It watches every rep

100 readings per second from elbow and wrist sensors detect the moment your form drifts from your personal best. Nothing slips through — whether it's your elbow, your wrist, or the relationship between the two.

03 — CORRECT

It speaks through touch

Four small vibration motors sit at the top, bottom, left, and right of your arm. Elbow flaring out? You'll feel a gentle pulse guiding it back in. The vibration tells you exactly which direction to adjust — and when it stops, you've nailed it.

We put elite performance in the hands of every young dreamer.

Every rep without feedback is a rep that reinforces bad habits. Betta makes sure every rep counts.
