π° What Happened
Blacksmith, a startup that helps companies build and test software faster, is now worth $1 billion. It raised $66 million in a round led by Sequoia. The company says its revenue has grown 17 times over the past year.
Blacksmith runs 'continuous integration' jobs, the automatic checks that test code before it ships. It has run more than 90 million of these checks. Customers include Mercury and Granola.
π The Backstory
More code is now written with AI help, and that means more code to test. Blacksmith's founders say companies cannot keep up with the volume of checks they need. Its boss says the real question is whether AI-written software can be trusted.
The jump in value has been fast. Blacksmith was worth $60 million a year ago and $550 million two months ago. It has raised $125 million in total.
π― Why It Matters
Software bugs cost money and can leak private data. Tools that test code quickly matter more as AI writes more of it.
