Ubisoft is a French video game publisher headquartered in Montreuil, founded in March 1986 by the Guillemot brothers. Since its establishment, Ubisoft has become one of the largest video game publishers, and it has the largest in-house development team, with more than 20,000 employees working in over 45 studios as of May 2021.[1]
While Ubisoft set up many in-house studios itself, such as Ubisoft Montreal, Ubisoft Toronto, Ubisoft Montpellier and Ubisoft Paris, the company also acquired several studios, such as Massive Entertainment, Red Storm Entertainment, Reflections Interactive and FreeStyleGames. Ubisoft's studios often cooperate with each other in their projects, sharing different development duties. Assassin's Creed Unity, released in 2014, saw ten studios worldwide work together.[2]
