Blacksmith, a start-up in San Francisco, got $66 million from investors in Series C. Sequoia Capital is the lead investor. The value of the company is $1 billion. In August it was $550 million. The company will get more computers and more engineers.
What is new
Blacksmith has a cloud service that assembles and tests software code with no manual work. This step is continuous integration. The company tells that AI agents write code faster and the test step is the slow step. The total is $125 million.
The numbers
The company gave these numbers. No other group checked them.
- Test tasks each week: more than 90 million, from 5 million in January.
- Revenue each year: 17 times more in the same time.
- Computers: almost 10 MW. The plan is 5 times more in 2027.
- Customers: more than 10,000 companies.
What is not known
The company gave no revenue number. It gave no test that compares its service with general cloud services. It tells that its service works with sudden peaks of work with no manual work.
Insight: Money moves to the step after the code
Blacksmith tells that the test step is the slow step. On 19 October 2026, Bright Security started a tool that tests code for bugs. 2 vendors sell the check of AI code. This reads as a race to own the gate that code must go through. The owner of the gate can set the price. Builders must plan the cost of tests.
