Joe Hewett is a founder and CTO with eight years of experience building secure, production-grade agent infrastructure that automates mission-critical browser and desktop workflows for regulated industries. Backed by Y Combinator and angels from OpenAI and Hugging Face, he leads Asteroid, which delivers HIPAA and SOC 2 Type II–compliant agents that replace brittle RPA and offshore teams. Previously at Netcraft he designed and deployed early LM-powered agents that engaged tens of thousands of scammers to extract fraud infrastructure intelligence. Joe blends hands-on engineering—building agent and automation stacks—with product-level security and compliance rigor. Outside work he’s as comfortable navigating distributed systems as he is navigating long overland journeys, having ridden 20,000+ km from Bangkok to Alaska and another epic trip from Costa Rica to Patagonia.
