Our take
Founded in 2000, Jagex is the video game studio behind the RuneScape titles. It is one of the largest British video game studios, having ammased 2.4 million active subscribers, one million free-to-play users, and over 300 million lifetime RuneScape accounts.
Jagex specialises in "forever games", in which players can continue to discover new experiences and challenges without ever reaching an end. RuneScape is a perfect example of this approach, still receiving updates over twenty years after its initial release.
On top of the RuneScape franchise, the company's acquisition of Gamepires brought titles such as SCUM under the company's banner, which it is also working to make into a forever game. It also acquired Pipeworks - adding a Games-as-a-Service platform to its broadening portfolio.
In 2024, it was announced that Jagex would be bought by CVC Capital Partners and Haveli Investments. This represents a move that will position it well to pursue creating more new and innovative player experiences in the future.
