Blacksmith, the software development platform that helps companies manage the continuous integration of code, including that written by AI, has hit unicorn status after raising $66 million in a Series C round led by Sequoia Capital. The company’s co-founder and CEO, Aditya Jayaprakash, said the goal was to make CI less painful for companies struggling to keep up with the volume of automated code checks, especially as more code is generated by AI agents.

‘Most companies are struggling to keep up with the volume of CI they need to run,’ Jayaprakash said in a blog post. ‘As agents write more of the world’s software, the question that matters is whether it can be trusted.’

Blacksmith claims its annual recurring revenue has grown 17 times since its inception, with over 90 million CI jobs run. Customers include Mercury and Granola. The company has raised $125 million to date, following a $45 million Series B valuation at $550 million and a $10 million Series A valuation at $60 million a year ago.

The rapid growth of Blacksmith and the increasing reliance on AI in code development raise questions about the future of software testing and the trustworthiness of AI-generated code. As Jayaprakash notes, the challenge is not just about making CI less painful, but also about ensuring the code is reliable and secure.
