About Our Hackerspace

Arch Reactor was founded in 2009 by a group of friends who liked technology, programming, making, and pizza. Now St. Louis' largest hackerspace, Arch Reactor's growing membership continues to bring new skills, projects, equipment, and people to one place.

For a deeper understanding of what we're about, you should check out our explanation of hackerspaces, perhaps read about one of our members' projects, or (best of all) come meet us in person at the next open event!
