Most Binary Builders Team Members Join Celestia as Firm Winds Down

Most of Binary Builders’ team has joined Celestia, co-founder Marko Baricevic announced Oct. 19, as the former Cosmos SDK maintainer prepares to stop accepting new projects.

Baricevic will not join the team at Celestia. He plans to take a break and explore other ideas. Binary Builders also plans to hand its validator operations to Validatus, with the transfer expected over the next few weeks.

Founded in 2022, Binary Builders became one of the main teams maintaining the Cosmos SDK and operated the Interchain Builders Program. In January 2025, it outlined plans to reduce its core maintenance work on the SDK and focus more on Celestia.

Most team members have now made the move to Celestia. The validator transfer to Validatus remains ahead.
