Blacksmith hits unicorn valuation after Sequoia leads Series C

Software testing platform Blacksmith has raised a $66 million Series C funding round led by Sequoia, reaching a $1.0 billion unicorn valuation. The company helps businesses manage continuous integration workloads, a need amplified by the rise of AI-generated code.
Why it matters
The rapid valuation increase underscores investor confidence in developer tools designed to handle the massive influx of AI-written software.
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.
In announcing the round, Blacksmith co-founder and CEO Aditya Jayaprakash said the company was founded to make continuous integration (CI) — the process of building, testing, merging, and validating code changes — “less painful.” In a blog post, he said that “most companies are struggling to keep up with the volume of CI they need to run,” especially in an era where so much code is written by AI.
“As agents write more of the world’s software, the question that matters is whether it can be trusted,” he added.
