Matsu: BJJ Coach

Matsu is the all-in-one app for BJJ and grappling coaches who run their own academy. Schedule classes, track every athlete, collect payments, prep competitors and sell team merch — all from your phone, with an AI assistant that actually knows your gym.

• Type, talk or send a photo — the assistant handles it
