Blacksmith reaches unicorn valuation in Sequoia-led Series C
Software testing startup Blacksmith has secured fresh capital as demand rises for tools that can handle growing volumes of AI-generated code. The $66 million Series C values the company at $1 billion and comes just two months after its previous funding round.
Highlights
- Blacksmith reached unicorn status in a Sequoia-led Series C, sharply increasing its valuation from $550 million at Series B to over $1 billion.
- Annual recurring revenue grew 17x and the company has processed more than 90 million CI jobs, serving customers like Mercury and Granola.
- The Series C funding, totaling $125 million raised to date, reflects investor demand for infrastructure tools that address the reliability of AI-generated code.
Funding round and growth metrics
As reported by TechCrunch, citing a company statement by Blacksmith, the new Series C is led by Sequoia and marks a sharp step-up in the startup's valuation from $550 million in its Series B round. The company says it helps businesses build and test software more efficiently, including code written by AI, through continuous integration workflows that cover building, testing, merging and validating code changes.Co-founder and CEO Aditya Jayaprakash says Blacksmith was founded to make continuous integration less painful as companies struggle to keep up with the amount of CI they need to run. He adds that, as agents write more of the world's software, the key question is whether that code can be trusted.
Blacksmith also says its annual recurring revenue has grown 17x and that it has run more than 90 million CI jobs, or individual automated code checks. Its customers include Mercury and Granola.
AI coding demand drives investor interest
The latest round comes only two months after Blacksmith raised a $45 million Series B that valued the company at $550 million. A year earlier, it was valued at $60 million after a $10 million Series A, bringing total funding raised to date to $125 million.The rapid increase in valuation underscores investor interest in infrastructure providers serving software teams as AI-generated code becomes more common. For the broader developer tools sector, Blacksmith's financing highlights how demand is shifting toward platforms that can improve code reliability and testing speed at scale.
