69-year-old Claude Guillemot, who founded Ubisoft alongside his four brothers, died on Friday, June 19, after his private twin-engine Cessna 421 crashed on approach to La Baule-Escoublac Airport in France, near the country’s Atlantic coast. Le Parisien said that Ubisoft has confirmed the passing of one of its founders in the accident.

“Ubisoft ‌was deeply saddened to learn of the death of Claude Guillemot, co-founder of the group and chairman ​of Guillemot Corp, in an accident,” the company said. “Our thoughts are with his family ⁠and loved ones during this difficult time. No ​further statements will be made at this time.”

Claude and his brothers founded Ubisoft in 1986 when they established the business by importing and distributing games in the country. It was also during that same year that it launched its first game, Zombi. In 1989, the startup was already making millions of dollars in sales and revenue, but it made its first globally successful original title, the platformer Rayman, in 1995. This allowed the company to go public in 1996, when it raised $80 million in its IPO.

Its successful public debut injected enough cash for it to open studios across the world, including Canada, China, and Japan. From humble beginnings, the company grew into one of the biggest names in gaming and entertainment, owning some of the most popular gaming titles and franchises in the past and present like Assassin’s Creed, Brothers in Arms, Far Cry, Ghost Recon, Rainbow Six, Prince of Persia, The Division, and Watch Dogs, among others.

Despite its success, Ubisoft has recently been facing some troubles. This includes a major cyberattack on its servers which forced the company to take Rainbow Six Siege completely offline as well as issues with generative AI in Far Cry 7, with one insider saying that it “looks like s**t.

The Guillemot brothers no longer own 100% of Ubisoft, although they still own a considerable stake. According to Investing.com, Guillemot Brothers S.A., a holding company that manages the brothers’ stake in Ubisoft, is still the largest shareholder with 12.27%, while institutional bank JPMorgan Chase & Co. is the second largest shareholder with 9.94%. Chinese gaming company Tencent Holdings Limited owns 9.46% of the company, with the rest spread out across different mutual funds and ETF, retail investors, and other institutional investors.

Claude Guillemot was the president of the Guillemot Corporation (different from the Guillemot Brothers S.A.), which was the original company founded in 1986 and still owns brands like digital audio solutions provider Hercules, DJ equipment maker Djuced, and gaming accessories manufacturer Thrustmaster. His younger brother, Yves Guillemot, still serves as the CEO of Ubisoft.

Aside from helping build one of Europe’s largest gaming empires, reports say that Claude also holds a pilot’s license and was an avid and experienced pilot. He was en route to the airport near the accident site for a planned air show this weekend when the tragedy struck. Alongside the Ubisoft co-founder, a 70-year-old flight instructor was also killed in the accident.

Officials haven’t made any statements yet regarding the cause of the accident. It will likely take months, if not years, before we get a comprehensive accident report from the Bureau d'enquêtes et d'analyses pour la sécurité de l'aviation civile (BEA), the French equivalent of the U.S. NTSB, tasked with investigating aircraft accidents.
