We build HQ because social media has become content to watch and algorithms to feed, not people to meet.
Our work is to give artists a direct home for the fans who actually care, and to help those fans find each other around shared music, shows, and local scenes.
We optimize for connection over attention, and for openness over status.
Founding artist community
BAUGRUPPE90 is the Berlin-based techno duo of Louis Köhler and Paul Vogler, building around sound, visuals, and the people who show up for both. HQ started as a place for that community to stay close between releases, shows, and shared moments.
