Supercell veteran Lasse Seppänen leaves to found UK studio in 2027

Seppänen’s CV at Supercell covers hands-on game leadership and studio-level responsibilities. He served as game lead on Hay Day, Boom Beach and Everdale, and spent time as head of game production services supporting all Helsinki-based teams. For the last year and a half he ran Supercell’s London studio, where he helped integrate the team after Supercell acquired Space Ape, the studio behind Beatstar.

His reasons for leaving are part practical and part personal. Seppänen said he’d been “daydreaming about the startup world again,” particularly with recent progress in AI tooling. He named digital card games as a category that, given today’s AI tools, “offers plenty of room to build entirely new kinds of game experiences,” and said he’s passionate about creating new game IP. He hasn’t shared firm details about the next studio yet, only promising more information “when the time is right.”

This won’t be Seppänen’s first time founding a studio. In the 2010s he was a founder at Elven Industries and PlayRaven, the latter of which was acquired by Rovio in 2018. His industry experience spans close to three decades and includes almost six years at Remedy Entertainment. On LinkedIn he thanked Ilkka Paananen, Sara Jansson Bach, Eino Joas and Janne Snellman, praised Supercell’s culture of trust and freedom, and noted he plans to hold on to his shares long term.
