About
Built for chess.
Designed for coaches.
GambitOS exists to unite chess schools of every size — from a solo coach to a national federation — and give them the operational backbone they need to focus on what truly matters: great chess.
Our story
Born from a real problem.Inside a real school.
We saw first-hand how chess schools operate: spreadsheets for scheduling, Telegram for parent updates, manual bank transfers for payments. Talented coaches spending hours on admin instead of the board.
GambitOS was founded in 2026 to change that. One platform to handle everything — so schools can grow, coaches can teach, and parents always know what is happening.
