Summary
Blacksmith, a platform that helps companies more efficiently build and test software, including code written by AI, announced Wednesday a $66 million Series C funding round led by Sequoia that values the company at $1 billion, according to the company's announcement as reported by the primary source.

Co-founder and CEO Aditya Jayaprakash said the company was founded to make continuous integration (CI), the process of building, testing, merging, and validating code changes, "less painful." In a blog post, he said that "most companies are struggling to keep up with the volume of CI they need to run," particularly as AI increasingly writes software. "As agents write more of the world's software, the question that matters is whether it can be trusted," he added.

The company also reported that its annual recurring revenue has grown 17x and that it has run more than 90 million CI jobs, or individual automated code checks. Customers named in the announcement include Mercury and Granola.

The Series C follows a $45 million Series B just two months earlier, which valued Blacksmith at $550 million. A year ago, the company was valued at $60 million after a $10 million Series A. In total, Blacksmith has raised $125 million to date.
