Blacksmith raises a $45.0M Series B round

Blacksmith makes CI faster, more cost-effective, and more reliable by avoiding hyperscaler-based solutions and running GitHub Actions on high-performance hardware with gaming-grade CPUs — tuned for maximum throughput and enhanced with growing observability capabilities. This approach eliminates build bottlenecks, lowers infrastructure costs, and gives teams a clear view into pipeline health. In the AI era, where rapid iteration is critical, Blacksmith keeps development cycles moving — enabling faster validation, safer deployments, and more competitive release schedules. Founded in 2024 by engineers from Faire and Cockroach Labs, Blacksmith is backed by Google Ventures, Y Combinator, and leading dev infrastructure angels.
