Claude Guillemot, who co-founded Ubisoft in 1986 and led gaming peripherals maker Guillemot Corp, has died at 69 in a plane crash in western France.
Claude Guillemot, one of five brothers who co-founded Ubisoft in 1986, has died in a plane crash near the coastal town of La Baule in western France. He was 69. Guillemot and a flight instructor from Rennes were both killed when their twin-engine Cessna 421 crashed in a field near La Baule aerodrome on the afternoon of 19 June.
French authorities confirmed that the aircraft was on fire when emergency crews reached the scene. Guillemot, a member of a local flying club, had departed Rennes and was travelling to an aviation gathering that was expected to draw more than 100 aircraft to the area. The cause of the crash has not been determined, and an investigation is underway.
Ubisoft confirmed the death in a statement, saying the company was “deeply saddened to learn of the death of Claude Guillemot.” The five Guillemot brothers, Claude, Yves, Michel, Christian, and Gérard, founded Ubisoft on 28 March 1986 in the Brittany village of Carentoir. What began as a software distribution business grew into one of the largest video game publishers in the world, behind franchises including Assassin’s Creed, Far Cry, Just Dance, and the Tom Clancy series.
Claude served as Executive Vice President in charge of operations at Ubisoft and sat on the company’s board of directors. His brother Yves remains chairman and chief executive of Ubisoft, which employs roughly 19,000 people across more than 40 studios worldwide.
Outside Ubisoft, Claude was chairman and CEO of Guillemot Corporation, the family’s publicly traded holding company that owns Thrustmaster, a major manufacturer of gaming peripherals including racing wheels, flight sticks, and controllers, and Hercules, which makes audio and DJ equipment. Guillemot Corp reported revenue of €197.7 million in its most recent fiscal year.
The Guillemot family’s grip on Ubisoft has been a recurring topic in the gaming industry. Despite holding roughly 11% of outstanding shares, the family maintains control through France’s Florange Act, which grants double voting rights to long-term shareholders. In 2022, Tencent, the Chinese conglomerate that has aggressively expanded its gaming portfolio, invested approximately €300 million in Guillemot Brothers Limited, the family’s private holding company, acquiring a 49.9% economic stake while receiving only 5% of voting rights.
That deal was widely interpreted as a defensive move, allowing the Guillemots to maintain control of Ubisoft while keeping Tencent’s influence capped. Tencent also holds a direct stake of approximately 9.46% in Ubisoft and invested €1.16 billion in Vantage Studios, a new Ubisoft subsidiary created in 2025 to manage the company’s biggest franchises. The question of whether Tencent and the Guillemot family would eventually pursue a full buyout has lingered for years, with no deal materialising as of June 2026.
Ubisoft has faced significant headwinds in recent years, including studio closures, layoffs affecting hundreds of employees, and a corporate restructuring that split the company into five creative divisions. The successful launch of Assassin’s Creed, a franchise that has expanded beyond games into film and television, helped stabilise the company after a difficult 2024, with Assassin’s Creed Shadows surpassing five million players within four months of its March 2025 release.
Claude Guillemot’s death comes at a particularly complex moment for the family business he helped build. Ubisoft is navigating activist investor pressure, an ongoing strategic partnership with Tencent, and a broader gaming industry contraction that has seen tens of thousands of jobs eliminated across the sector since 2023.
He is survived by his brothers and his family. French media reported that tributes from the gaming industry and the Brittany business community began arriving within hours of the announcement.
