Blacksmith has raised $66 million in a Series C funding round led by Sequoia Capital. The deal values the software testing platform at $1 billion as AI-generated code increases demand for automated checks.
Blacksmith has secured fresh backing from investors including Premji Invest and existing investor Peak XV Partners. The round brings its total funding to $125 million, with plans to strengthen its compute infrastructure and expand its technical engineering team.
Blacksmith provides a specialised cloud platform for automatically building and testing software. This work forms part of continuous integration, which checks code changes before deployment, and is becoming a bottleneck as AI agents produce more code.
Blacksmith says it manages nearly ten MW of compute capacity across data centres in the United States and Europe, with plans to expand capacity by 5X in 2027. For companies using AI coding tools, the expansion addresses the testing work needed to turn more generated code into software they can ship.
The funding commits capital to the testing infrastructure that companies need as AI increases code output.
Faster code generation makes validation capacity a more important constraint on how quickly companies can ship software.
The planned capacity expansion is not yet delivered, so builders still need to assess whether Blacksmith can meet their testing demand.
