Bare-metal runners for GitHub Actions CI
We started by building infrastructure to run CI workloads really fast. Our first product helps companies run GitHub Actions substantially faster and cheaper by owning and operating our own global fleet of bare-metal machines rather than renting generic cloud VMs.
Today, we orchestrate tens of millions of Firecracker VMs each week, running CI for 10,000+ companies and tens of millions in ARR. We’ve grown 20x so far in 2026.
We operate thousands of bare-metal machines across multiple regions, regularly schedule 300k+ vCPUs concurrently, and run a petabyte-scale Ceph cluster that we manage ourselves.
We’ve raised $125M from Seed to Series C, led by Sequoia, Google Ventures (GV) & Peak XV Partners, and we’re intentionally building a small, but exceptional team.
Blacksmith was founded by a team with deep systems and scaling experience, including building search/ads infrastructure at Faire, and operating large distributed systems at Cockroach Labs. Our GTM is led by Jon Boyer, formerly Head of Sales at Zapier.
We're now extending the same CI infrastructure into a broader platform: running agent sandboxes at scale and building our own background coding agent on top of it.

Bare-metal runners for GitHub Actions CI
Blacksmith helps software teams run GitHub Actions CI workflows on fast bare-metal servers instead of typical cloud VMs. It acts as a drop-in replacement for GitHub-hosted runners, requiring only a one-line change in the workflow to switch, while preserving existing GitHub Actions definitions. It uses high-performance bare-metal CPUs to speed up builds and offers caching, machine definitions, and a CLI to manage jobs and usage, plus observability features like log search, test analytics, and failure triage. It targets thousands of companies by advertising faster, cost-efficient CI and better debugging tools. The goal is to provide reliable, faster CI with lower costs and better visibility, helping engineering teams ship code more quickly.
