Ubisoft Co-Founder Claude Guillemot Dies in Cessna 421 Crash

The Tragic End: Claude Guillemot's Final Flight in a Cessna 421

On the afternoon of June 19, 2026, a twin-engine Cessna 421 crashed in a field in La Baule, France, killing both people on board. Among the victims was Claude Guillemot, the co-founder of Ubisoft and owner of the aircraft.

The plane had taken off from Rennes and was headed to La Baule, where an event involving more than a hundred aircraft was scheduled. Upon crashing, the aircraft burst into flames, and the fire spread to the surrounding vegetation. Firefighters from the Loire-Atlantique department responded, but both occupants — the pilot and Mr. Guillemot — were deceased.

“It was a Cessna 421, a twin-engine propeller aircraft with eight seats, which took off from Rennes,” said Franck Louvrier, mayor of La Baule, in an interview with Ici Loire Océan.

The other victim was identified as an instructor from Rennes. The news was confirmed by Ouest-France and reported by France Info. The crash remains under investigation.

From Co-Founder to Gaming Icon: Claude Guillemot's Role at Ubisoft

Claude Guillemot was one of the five Guillemot brothers who founded Ubisoft in 1986. Starting as a small French publisher, the company grew into a global entertainment giant under their leadership. Claude played a key role in that expansion, overseeing business strategy and helping to establish Ubisoft's reputation for high-quality, narrative-driven games.

Ubisoft's catalog includes some of the most recognizable franchises in gaming history. Guillemot was instrumental in the development of Assassin's Creed, Far Cry, and Tom Clancy's Rainbow Six series. These titles not only defined genres but also set technical benchmarks for open-world design and emergent gameplay.

His business acumen helped Ubisoft navigate the shift from physical media to digital distribution, and from single-player experiences to live-service models. The company's stock rose steadily during his tenure, and it became one of the largest video game publishers in the world by revenue.
