Factory.ai is a multi-agent software engineering platform. A coordinator Droid decomposes work and assigns specialized Droids covering code, review, tests, documentation, knowledge indexing, and deployments. The coordinator maintains high-level context while Droids execute; tests precede implementation, validation runs as a large fraction of total task runtime, and changes require approval before being pushed to Git.
The Knowledge Droid builds a codebase index using HyperCode and ByteRank, amortizing the one-time indexing cost across sessions so subsequent tasks carry codebase context without re-indexing. Execution that mutates code runs serially by design; parallel execution is limited to read-only paths.
Droid Computers are Factory-managed VMs (4 vCPU, 8 GB RAM, 6 GB swap, auto-pause) for remote background agent execution. Integrations cover GitHub, GitLab, Linear, Jira, Slack, Notion, Sentry, and PagerDuty; Bitbucket and Azure DevOps are not documented as of May 2026. The company raised a $150M Series C at a $1.5B valuation in April 2026.
