IO Interactive was founded in September 1998 in Copenhagen, Denmark by the Reto-Moto development group. To date, their most popular franchise is the critically acclaimed Hitman series. IO Interactive remained a subsidiary of Square Enix until 2017, when its parent started seeking buyers for the studio. IO Interactive completed a management buyout, regaining their independent status and retaining the rights for Hitman and Freedom Fighters, in June 2017.

It’s simple. Io-Interactive is here to deliver exciting world class entertainment, and we want our games to play and feel like the people who created them. It is our way of making sure that we will always deliver something unique and interesting. This requires not only lots of work but also lots of guts, talented people and a great working environment and we do our utmost to have all of this.

We’re doing as much as we can to make IOI feel like a second home. We meet in the morning and share breakfast, eat lunch together and party together. On Fridays we sometimes have our Friday bar – either planned as a big thing where we run around in the building with laser guns – or just spontaneously started somewhere in the building. Every now and then we have IOI days where we can dig into our pet projects or attend presentations from colleagues or external experts on everything game related.

Around Christmas, we usually have the house full of all our kids making ginger bread houses and paper cuttings. In the summertime there are often football games going on and besides these three cornerstones of Denmark (food, beer and football) there’s a thing like the monthly board game night where we just go totally analogue.
