About Acyclic Labs
Summary
Acyclic Labs builds infrastructure for running agent swarms that tackle software tasks too large for a single coding agent. Engineers point it at a repository and describe a task; the swarm splits the work across parallel agents, each running in its own sandbox, and merges the output into a patch or pull request. It replaces the manual effort of coordinating multiple AI coding sessions and stitching their results together.
Business model
Pay for active compute and divergent state consumed during a swarm run.
Go-to-market
Targets startups building domain-specific agents, companies already operating production swarms, and teams running high volumes of Claude Code or Codex sessions on large codebases; access to the flagship Graphcoder product is invite-only, with interested teams requesting a conversation through the website.
