Stockholms Improvisationsteater

Martin Geijer founded Stockholms Improvisationsteater in 1989 as an amateur theater rooted in improvisational technique, with early connections to Keith Johnstone's work that was gaining prominence in Scandinavia. The company acquired its own permanent stage in 1992 and has remained at that location ever since, the only permanent stage in the Nordic region dedicated exclusively to improvisational theater. Geijer has written the foreword to a Swedish-language edition of Keith Johnstone's writings and is recognized as one of Sweden's leading educators in improvisational theater, body language, and creativity. Improstudion, which Geijer also founded, operates as a related entity offering courses and weekly shows.

SIT performs exclusively in Swedish, creating productions that engage with Swedish literary, theatrical, and cultural traditions through the lens of improvisation. The programming spans ensemble-devised shows with recognizable cultural touchstones, senior improv programs, and a deep multi-level curriculum from beginner to advanced. The theater treats improvisation as a discipline equally suited to personal development, professional performance, and corporate engagement.

Stockholms Improvisationsteater is the oldest and largest improv institution in the Nordic region, having established a permanent stage in 1992 that remains the only venue in Scandinavia dedicated exclusively to improvisation. Martin Geijer's founding work created the infrastructure through which Swedish improv professionalized over the following three decades.
