Stuart Muckley and Martin Thomas formed Code Wizards Group back in 2002, bringing together a combined 50 years of coding and video games experience.
Since then, they have assembled teams of battle-hardened veterans across both Code Wizards and Multiplayer Wizards; professional services on a mission to help esports orgs, AAA studios, and indies alike build and run successful games.
The secret behind our success? We care about our clients' games and players as much as they do.
Code Wizards Group is a world leader in backend and multiplayer infrastructure for the gaming industry. From high-scale AAA console and PC games to fast-paced mobile indie titles, we empower studios to bring multiplayer experiences to life.
