Acyclic runs agent swarms. Hand it a task from the CLI, the dashboard, or a coding agent over MCP, and it splits the work across many agents, each in its own sandbox, then merges what they produce into one result. Long agentic workflows finish in a fraction of the wall-clock time. Bring your own model keys or run the sandboxes in your own cloud; the harness underneath is open source. Coding is the first workload, and research and data work run the same way. Founded by Ram Vinjamuri and Varun Latthe. YC F26, London.
