Blacksmith, a platform for building and testing software, said Wednesday it raised a $66 million Series C round led by Sequoia that values the company at $1 billion.
The company says its tools help businesses manage continuous integration, the process of building, testing, merging and validating code changes, more efficiently, including code produced by AI.
Co-founder and CEO Aditya Jayaprakash said Blacksmith was founded to make continuous integration less painful. In a blog post, he said most companies are struggling to keep up with the volume of CI work they need to run, particularly as more code is written by AI. He added that as agents write more of the world's software, the question that matters is whether that code can be trusted.
Blacksmith also reported that its annual recurring revenue has grown 17x and that it has run more than 90 million CI jobs, the individual automated code checks the platform performs. Its customers include Mercury and Granola.
The Series C arrives two months after a $45 million Series B that valued Blacksmith at $550 million. A year ago, the company was valued at $60 million following a $10 million Series A. Blacksmith has raised $125 million to date.
The new valuation places Blacksmith among the ranks of unicorns, private companies valued at $1 billion or more, a milestone reached as software testing increasingly shifts toward code generated by AI agents.
