Blacksmith reaches a valuation of $1 billion, driven by the boom in AI-generated code

The continuous integration start-up has raised $66 million in a round led by Sequoia, two months after a Series B round that valued the company at 550 million, and says it carries out 90 million checks a week.

Blacksmith, which provides the infrastructure on which companies test their code before putting it into production, has closed a $66 million Series C round led by Sequoia Capital, at a valuation of $1 billion. Just two months ago, the start-up raised $45 million (Series B led by Peak XV) with a valuation of $550 million; its total funding is now around $124.5 million.

A direct effect of the programming agents

The growth follows that of AI-generated code: more than 10,000 companies use the platform, compared to about 5,000 in August, including Granola, Handshake, Supabase and LangChain. The volume of verifications has increased from 5 million per week at the beginning of the year to 90 million, and annual recurring revenue has increased 17-fold over the period, to reach several tens of millions of dollars, according to CEO Aditya Jayaprakash.

Rather than renting servers from AWS, Google Cloud or Azure like most continuous integration players, Blacksmith buys its own machines, by the tens of thousands, spread over data centers around the world. Most of the funds will be used to acquire computing power; the workforce of about forty people is expected to rise to about 75 by the end of the year.
