# Blacksmith Raises $45 Million Series B for AI Code Validation

> Blacksmith raised a 45 million dollar Series B led by Peak XV Partners at a 550 million dollar valuation, roughly a tenfold jump in under a year. The company runs continuous integration workloads on purpose-built hardware, and its pitch rides a very current wave: as AI generates more and more code, teams need to test and validate that code far faster than before. The traction numbers are the striking part. Blacksmith says its customer count leapt from 800 to 6,000 companies, with weekly CI jobs growing 5 to 10 percent week over week, and its client list includes developer-infrastructure names like Supabase, Clerk and Ashby. Y Combinator and GV joined the round alongside Peak XV. It is a neat example of a second-order AI business. Blacksmith does not build models, it sells the picks and shovels that the AI coding boom suddenly requires, and if the volume of machine-written code keeps climbing, the demand for somewhere fast to check it climbs right alongside.
