Claude Guillemot Biography

French businessman and co-founder of Ubisoft, Claude Guillemot helped transform a family trading operation into an international video game publisher. A sh

Early life and background

Claude Guillemot was born on 30 October 1956 in Carentoir, a village in Brittany, France. He grew up in a farming family and worked alongside his four brothers in various aspects of the family business as they sought ways to improve its profitability. Claude completed higher education in Brittany, earning a master’s degree in Economic Science from the University of Rennes 1 and an Industrial Computing Certificate from Institut Catholique d'Arts et Métiers (ICAM) in Lille.

Career

In the early 1980s Claude and his brothers moved beyond the farm trade into commerce, initially selling agricultural chemicals and parts. They soon expanded into selling computers and software. In 1984 the brothers launched a mail-order business for video games after discovering that importing technology from the United Kingdom could be more economical than buying locally in France. That operation grew quickly, adding distribution to retail outlets that wanted access to competitively priced games.

Two years later, in 1986, Claude and his brothers formally founded Ubisoft Entertainment SA. The company began as a small software distribution business and evolved into a global video game publisher known for franchises such as Assassin’s Creed, Far Cry, Prince of Persia and Tom Clancy titles. Claude generally worked behind the scenes, focusing on the operational and business systems that supported the company’s growth, while other family members took on more public-facing roles.

Beyond Ubisoft, Claude served as president and CEO of Guillemot Corporation, a firm that specialized in equipment and accessories for PCs, mobile devices and consoles. From 1997 until 2026 he was actively involved in the company’s expansion, including the development of research and development and logistics centers across Europe, Canada and China.

Public profile

Although not the most visible Guillemot publicly, Claude played a sustained leadership role in French business circles. Beginning in 2009 he served as president of the Club des Trente, an organization that gathers around 60 French chief executives to exchange ideas and take positions on socio-economic debates. He maintained a reputation as a private, operationally focused executive who contributed to the infrastructure and logistics that enabled Ubisoft’s international growth.

Personal life

Claude was married and a father of three children, including a son, Valentin Guillemot, who is identified as a businessman. He was one of five brothers; his siblings Michel, Gérard, Christian and Yves Guillemot were all involved in the family enterprises. Claude’s appearance in later years was described as having salt-and-pepper hair and blue-hazel eyes. He was French by nationality and identified with Christianity.

Death and legacy

Claude Guillemot died on 19 June 2026 at age 69 when the Cessna 421 Golden Eagle aircraft he was piloting crashed while approaching La Baule-Escoublac Airfield in Pays de la Loire, France. The aircraft was destroyed in the accident, and a flight instructor on board also lost their life. Ubisoft issued a brief statement expressing sorrow at the loss of its co-founder and chairman of Guillemot Corp., extending condolences to his family and loved ones.

Latest updates

At the time of his death, Claude had been active in business leadership and in promoting the expansion of R&D and logistics operations internationally. His passing was reported in June 2026 following the plane crash near La Baule-Escoublac; Ubisoft confirmed his death and noted it would not be issuing further statements at that time.
