Ubisoft co-founder Claude Guillemot was killed in a plane crash in western France on the evening of June 19, 2026, at the age of 65.
Guillemot and a flight instructor both died when the twin-motor Cessna 421 they were traveling in crashed into a field near La Baule-Escoublac Airport.
Ubisoft, the gaming company behind major global franchises such as Assassin's Creed, Just Dance, Rayman, and the Tom Clancy series, confirmed Guillemot's death but did not comment further.
Claude Guillemot founded Ubisoft in 1986 alongside his four brothers: Yves, Michel, Gerard, and Christian.
Beyond his early role in establishing Ubisoft, Claude Guillemot was a pioneering figure in the French technology and multimedia sectors.
Over the past four decades, he and his brothers expanded the family-run enterprise from a small computer software distributor in Brittany into one of the largest publicly traded video game publishers in the world.
In addition to his contributions to Ubisoft's global strategy, Claude served as the longtime CEO of Guillemot Corporation, a sister company specializing in hardware and interactive gaming accessories under brands like Hercules and Thrustmaster, cementing his legacy as a foundational pillar of modern interactive entertainment.
In a statement to FOX Business on Saturday, Ubisoft said it was "deeply saddened to learn of the death of Claude Guillemot, co-founder of the Group and President of Guillemot Corporation, in an accident."
