Sumo was founded in 2003 and quickly established itself as a reliable and collaborative development partner for premier games publishers around the world.

As our experience grew, so did our versatility. We quickly became a multi-project, multi-genre solution provider, developing award-winning titles for every gaming platform.

Sumo Digital was originally set up as a ‘work for hire’ games developer, working alongside developers and publishers for certain sections of a game’s production. Successful delivery of co-development projects enhanced the company’s experience of franchise IP, enabling us to eventually take responsibility for full turnkey projects.
