Claude Guillemot, one of the founders of Ubisoft, a major video game company, died on June 19, 2024, when a small plane he was flying crashed near La Baule on France's Atlantic coast. He was 69. One other person on the plane also died, according to Deadline.

Guillemot was piloting the aircraft. Authorities in France have not yet released details about what caused the crash.

Ubisoft is a major video game publisher known for games like Assassin's Creed, Far Cry, and Rainbow Six. The company was founded in 1986 by five brothers from Brittany, in northwestern France. Claude was one of those five brothers. His brother Yves has run the company as its CEO for most of its history. What began as a small family business selling games by mail grew into one of the world's largest independent game publishers.

The company has been around for nearly 40 years and has adapted to every major shift in gaming — from cartridge-based games to CDs to games played online to free games supported by ads and in-game purchases. Even now, the company is incorporating AI tools into how games are made. Most game companies founded back in the 1980s either disappeared or were bought by larger companies. Ubisoft survived by making smart choices early on, including decisions to expand aggressively into North America and Asia.

Recently, Ubisoft has faced some difficulties. Several of its games have not sold as well as expected, the company has undergone restructuring to cut costs, and there has been speculation about whether larger companies like Tencent might buy it. None of this changes the significance of Guillemot's death, but it does mean the news arrives at a time when the founding family's role at Ubisoft is a topic of industry conversation.

The Cessna 421 is a small, twin-engine airplane that was first built in the late 1960s. It is not a particularly advanced aircraft, but flying one safely requires training and experience, especially in bad weather. We do not yet have details about what the weather was like or exactly what happened near La Baule.

Guillemot's death means his brother Yves and the rest of the founding family now carry on what these brothers built together. When a founder of a major company dies, it matters beyond the personal loss. The founding generation holds memories and relationships built over decades that are hard to replace, no matter what their official title might have been. This is a practical fact about how family-run businesses actually work.

Claude Guillemot was 69 years old.
