    Report first recorded Oct 22, 07:47

    Blacksmith, a platform for efficiently building and testing software including AI-written code, announced a $66 million Series C funding round led by Sequoia, valuing the company at $1 billion. The company reported a 17x growth in annual recurring revenue and has executed over 90 million CI jobs, with customers including Mercury and Granola. This follows a $45 million Series B at a $550 million valuation two months prior, and a $10 million Series A when it was valued at $60 million a year ago. Co-founder and CEO Aditya Jayaprakash said the company was founded to make continuous integration (CI) less painful, noting that most companies struggle with CI volume, especially as AI agents write more software, raising trust concerns.
