Ai

Patronus AI closed a $50M Series B today led by Greenfield Partners, bringing total funding to $70M. The San Francisco startup, founded by former Meta AI researchers Anand Kannappan and Rebecca Qian, builds digital world models that replicate enterprise systems so AI agents can be stress-tested before real deployment. Revenue has grown 15x in the past year as enterprises seek reliability guarantees that model providers alone aren't offering.
