Ubisoft Co-Founder Claude Guillemot Dies at 69

Ubisoft co-founder Claude Guillemot died at 69 on June 19, 2026, in a plane crash near La Baule on the western coast of France.

He was one of five brothers who started Ubisoft in 1986 and ran the family's gaming hardware business, and his death lands at a fragile moment for a publisher already under heavy financial and structural pressure.

Who Was Claude Guillemot and How Did He Die?

Claude Guillemot was one of the five Guillemot brothers who co-founded Ubisoft, and at Ubisoft he served as Executive Vice President in charge of operations while sitting on the board of directors, according to The Next Web.

He died when a twin-engine Cessna 421 crashed in a field near the La Baule aerodrome on the afternoon of June 19, killing both him and a flight instructor from Rennes.

The reporting agrees on the core facts but draws on different chains: Engadget credits Ouest France with the first report and notes the aircraft was on fire and spreading to the surrounding area when responders arrived, while Forbes cites France's ICI news network and a company statement issued to Bloomberg.

What the sources do not yet have is a cause, because French authorities have opened an investigation and have not determined why the plane went down.

Ubisoft confirmed the death in a short statement, saying it was "deeply saddened to learn of the death of Claude Guillemot, co-founder of the group and chairman of Guillemot Corp.," and adding that no further statements would be made at this time.

His Role Among the Five Founding Brothers

The five brothers, Yves, Claude, Michel, Christian, and Gerard, founded Ubisoft on March 28, 1986, in the Brittany village of Carentoir, per The Next Web.

A small detail worth flagging is that the spelling of the fifth brother diverges across coverage: The Next Web writes "Gerard" with an accent while Forbes writes it without, a reminder that even agreed-upon facts carry minor reporting variance.

Yves Guillemot is the public face of the company and remains its chairman and chief executive, a separation of duties that mattered: Claude ran operations and hardware, Yves ran the publisher.

That division shows in Claude's outside role, where he was chairman and CEO of Guillemot Corporation, the family's publicly traded holding company.

Guillemot Corp owns Thrustmaster, a major maker of racing wheels, flight sticks, and controllers, and Hercules, which makes audio and DJ equipment, and it reported revenue of 197.7 million euros in its most recent fiscal year, according to The Next Web.

Ubisoft's Financial State, by the Numbers

Ubisoft is large but under strain, and the clearest way to see the tension is to put the operational scale next to the market valuation as the sources report them.

The gap that matters here is the share price: Forbes reports a fall from $23 in 2018 to $1.12, which is a collapse in market value even as the company still employs roughly 19,000 people.

The catch is that scale and valuation are pulling in opposite directions, and the family business Claude helped build is worth far less per share than it was eight years ago despite remaining an industry heavyweight.

One bright spot is Assassin's Creed Shadows, which The Next Web says passed five million players within four months of its March 2025 release and helped stabilize the company after a difficult 2024.

What His Death Could Mean for Ubisoft's Future

The bigger question for gamers is control, because Ubisoft's franchise direction has long been tied to the Guillemot family's grip on the company.

The Next Web reports the family holds roughly 11% of shares but maintains control through France's Florange Act, which grants double voting rights to long-term shareholders, so a single founder's death does not by itself shift voting power.

The wildcard is Tencent, which in 2022 invested about 300 million euros into the family's private holding company for a 49.9% economic stake but only 5% of the voting rights, a structure widely read as a defensive move to cap outside influence.

Tencent also holds a direct stake of around 9.46% in Ubisoft and put 1.16 billion euros into Vantage Studios, a 2025 subsidiary created to manage the company's biggest franchises, per The Next Web.

That last point matters for franchise fans, because the games people care about, including Assassin's Creed, Far Cry, Just Dance, and the Tom Clancy series, increasingly sit inside that Tencent-funded Vantage structure rather than the legacy Ubisoft parent.

Forbes notes there are no plans to slow the release slate, but the same coverage describes a company that has weathered past talk of sales and privatization, so the long-rumored full buyout question stays open with no deal as of June 2026.

For now the practical takeaway is narrow: Claude's death is a loss for the founding family and for the hardware side of the business, but the voting structure and the Tencent partnership, not any single brother, are what will decide where Ubisoft and its franchises go next.
