ORIGIN STORY

It started with one agent.

OpenBuilder began in 2026 as OpenClaw Singapore, a community night for people running a single open-source agent. As the community grew, the conversations expanded beyond that one tool to open models, agent harnesses, hardware and enterprise deployment.

The name was changed to reflect that scope. OpenBuilder is the same community under The AI Capitol, now spanning the full open-source stack: platform-agnostic, vendor-neutral and free to join.

"My vision is to create a community of AI builders, founders and enterprise owners to learn and grow together."

Lionel Sim, Founder of OpenBuilder
