About Blacksmith
At Blacksmith, we revolutionize the way companies handle CI workloads. Our innovative products significantly enhance the speed and cost-effectiveness of GitHub Actions by leveraging our own global fleet of bare-metal machines, rather than relying on traditional cloud VMs.
In just two years, we've achieved remarkable success, orchestrating tens of millions of Firecracker VMs monthly for over 1,200 companies and reaching an ARR of approximately $10M.
Our infrastructure consists of thousands of bare-metal machines across various regions, efficiently scheduling over 30,000 vCPUs concurrently, while managing a petabyte-scale Ceph cluster in-house.
Backed by $13.5M in funding from esteemed investors like Google Ventures, we pride ourselves on building a compact yet exceptional team.
Our founding team boasts deep expertise in systems engineering and scalability, having previously developed search and ad infrastructure at Faire and managed large-scale distributed systems at Cockroach Labs.
We are now expanding our CI infrastructure into a comprehensive platform, focusing on running agent sandboxes at scale and developing our own background coding agent.
