Arbitrum Open House Gather @ETHDenver
Open to Everyone. Built for Everyone.
Arbitrum Open House Gather heads to Denver! Come join us.
About this event
Open House Gather is a casual, in-person meetup for builders, founders, and contributors who are curious about building on Arbitrum and getting involved in the broader ecosystem.
Hosted at Shake Shack in Denver, this gathering brings the community together over food and conversation while introducing Open House, a global builder initiative designed to support learning, collaboration, and early-stage building.
Open House culminates in an in-person Founder House where selected teams come together to build, experiment, and ship alongside peers and mentors.
