Blacksmith is a rapidly growing company that started by building infrastructure to run CI workloads very fast. Their first product helps companies run GitHub Actions faster and cheaper by operating their own global fleet of bare-metal machines. They currently orchestrate millions of Firecracker VMs weekly, serving over 5,000 companies and achieving approximately $50 million in ARR within 2.5 years, with revenue increasing more than fivefold since the start of 2026. The company operates thousands of bare-metal machines across multiple regions, concurrently schedules over 100,000 vCPUs, and manages a petabyte-scale Ceph cluster. Having raised $58.5 million from Seed to Series B, led by Google Ventures (GV) and Peak XV Partners, Blacksmith is focused on building an exceptional team. The founding team has extensive experience in systems and scaling, including building infrastructure at Faire and operating large distributed systems at Cockroach Labs. The Go-to-Market (GTM) strategy is led by Jon Boyer, former Head of Sales at Zapier. Blacksmith is now expanding its CI infrastructure into a broader platform, which includes running agent sandboxes at scale and developing its own background coding agent.
