AI-Powered Training System

THE BEST DEAL
IN GRAPPLING

AI-powered tools to track your progress, map your game, and get jacked. Plus a monthly shirt you'll actually want to wear. $1 a day. Either the best deal in grappling or we're terrible at math.

OSS Club Drop 01 Guillotine tee — gym lifestyle

The OSS Software Suite

FOUR TOOLS.
ONE SYSTEM.

Everything you need to track, analyze, and improve your jiu-jitsu game. Built by grapplers who got tired of scattered notebooks and generic fitness apps.

Oh, and one more thing

WE ALSO MAKE SHIRTS

Every month, a new exclusive design shows up at your door. Parody brands. BJJ inside jokes. Stuff only your training partners will understand.

We spent months building AI-powered training software to help you map your game and track your progress.

We also made shirts that are puns on beer brands.

Both feel equally important to us.
