Blacksmith hits unicorn valuation after Sequoia leads Series C

What changed

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. “As agents write more of the world’s software, the question that matters is whether it can be trusted,” he added. The company also announced that its annual recurring revenue has grown 17x and that it has run over 90 million CI jobs, or individual automated code checks.

Why it matters
