KAYYO

What it does

KAYYO is a competition layer for real-world sports leagues. It runs the Internet Fight League, covering boxing, jiu-jitsu and Muay Thai. Boxing tracks sparring and rounds. Jiu-jitsu counts rolls, belts, gyms and open-mat matchmaking. Zeus offers AI motion coaching for Muay Thai from a phone.

KAYYO presents itself as the IRL competition layer of the internet, with real sports, real stakes and one leaderboard. The homepage lists three tracks inside the Internet Fight League. Boxing is for tracking sparring and logging rounds to climb a pound-for-pound ranking. Jiu-jitsu counts every roll and covers belts, gyms and open-mat matchmaking. Zeus is AI motion coaching for Muay Thai, described as for the eight limbs, from your phone. The page shows a live status and several redacted entries, so the full league data is not visible. There is no pricing page and no statement about accounts, an API or source code. The homepage is short, so details on how rounds and rolls are verified, what the motion coaching records, and whether new gyms can join are not available here.
