417 was founded in 2017 by four longtime friends and veterans of the music world, who came together with a shared vision for pushing the boundaries of event production. Originally created as the team behind the iconic northern gathering, Solstice Festival, and the celebrated castle rave, Retriitti, 417 quickly established a well-regarded name in the industry, recognized for its innovation, quality, and reliability.

In 2018, we launched Post Bar, a dance-music-focused nightclub in Helsinki’s vibrant Kallio district, which has since become a defining part of what we do. Hosting hundreds of renowned artists yearly and pushing boundaries in both programming and other aspects, Post Bar has become a staple in the international club scene.

Whether it’s our own events in unique locales—from mountaintops to offshore islands, gallery spaces to sprawling warehouses—or selected projects for clients, our focus is on fusing all aspects of the senses into an immersive experience.

With diverse expertise in event production, video, advertising and music, as well as architecture, we bring a multidisciplinary approach to every event. Collaborating closely with artists, musicians, and skilled technicians, we thrive on partnerships and the energy of creative exchange, continually bringing fresh ideas to life and elevating the cultural landscape around us.
