Blacksmith, a platform that helps companies build and test software including code written by artificial intelligence, has raised $66 million in a Series C round led by Sequoia Capital at a $1 billion valuation.
The company, founded in 2024 by Aditya "JP" Jayaprakash, Aayush Shah and Aditya Maru after they met as University of Waterloo undergraduates, provides cloud infrastructure for continuous integration (CI), the automated process of building, testing and validating code changes before deployment.
Less painful
Co-founder and CEO Jayaprakash said Blacksmith exists to make that process "less painful," noting in a blog post that "most companies are struggling to keep up with the volume of CI they need to run" as AI writes more code.
"As agents write more of the world's software, the question that matters is whether it can be trusted," he said.
Blacksmith said its annual recurring revenue has grown 17-fold and that it has now run over 90 million CI jobs, with customers including Mercury and Granola; its customer base had already grown from more than 700 companies at the Series A to over 5,000 by the Series B.
The Series C arrives just two months after a $45 million Series B that valued Blacksmith at $550 million, led by Peak XV Partners with GV and Y Combinator participating, and roughly a year after a $10 million Series A valued the company at $60 million; Premji Invest and existing investors joined the latest round, taking total funding raised to $125 million.
