Blacksmith Raises $66M to Expand CI Infrastructure
Blacksmith raised $66M Series C led by Sequoia Capital to scale its specialized computing platform for code building and testing.
The big picture: Blacksmith, a software infrastructure company specializing in code building and testing, has raised $66 million in Series C financing led by Sequoia Capital. The round values the company at $1 billion, bringing its total funding to $125 million.
Why it matters:
- AI-driven code generation: The proliferation of AI coding tools is accelerating software development, leading to a significant increase in the volume of code that engineering organizations must validate before deployment.
- Infrastructure bottlenecks: Traditional continuous integration (CI) systems, often relying on general-purpose cloud resources, struggle to manage the growing computational demands and rapid fluctuations in demand associated with extensive software testing.
- Cost and complexity reduction: Blacksmith’s specialized platform helps companies manage these increased workloads, reducing the costs and operational complexity of maintaining their own testing infrastructure.
How it works:
- Optimized for CI workloads: Blacksmith has developed infrastructure specifically for continuous integration, allowing computing capacity to expand and contract dynamically in response to changing customer requirements.
- Scalable and efficient: The platform accommodates extreme fluctuations, from minimal activity to tens of thousands of CPUs, without requiring customers to provision or scale their own CI infrastructure.
- Proven impact: The company reports that developers using its infrastructure complete CI jobs twice as fast and achieve an average cost reduction of 60% compared to previous environments.
The catch: While Blacksmith addresses a critical need, the market for developer tools and infrastructure is highly competitive. Major cloud providers could develop or acquire similar specialized CI solutions, and the rapid evolution of AI coding agents means Blacksmith must continuously innovate to stay ahead of changing development workflows and infrastructure demands.
