Ubisoft is a French video game publisher and developer, one of the largest independent game companies in the world. It is founded in 1986 by the five Guillemot brothers, Christian, Claude, Gérard, Michel, and Yves, in Carentoir, Brittany, initially as a distributor of software to French farmers-turned-retailers before moving into game publishing and development. Yves Guillemot serves as chief executive from the start. The company's breakthrough comes with Rayman in 1995, and its modern identity is built on major franchises including Assassin's Creed, Far Cry, Tom Clancy's Rainbow Six Siege, Ghost Recon, Watch Dogs, The Division, and Just Dance, with Assassin's Creed alone selling over 200 million copies. Ubisoft is known for pioneering the large open-world action formula and for its worldwide studio network of roughly 45 locations, including Ubisoft Montreal, one of the biggest game development studios anywhere, which it opens in 1997. The company is headquartered in Saint-Mandé, near Paris, employs around 18,000 people, and trades on Euronext Paris under Guillemot family control. In 2025 Ubisoft creates a subsidiary housing its Assassin's Creed, Far Cry, and Rainbow Six brands, with Chinese technology group Tencent investing 1.16 billion euros for a minority stake, a move intended to accelerate development of its biggest franchises. Ubisoft also operates Ubisoft Connect, its own PC platform and cross-progression ecosystem, and licenses its properties for films, series, and theme park attractions.
