Aaron Leon

Founder of Hubble, AI-native retrieval engine for medical records

Company

Aaron Leon is listed as a founder of Hubble. Hubble is the AI-native retrieval engine for medical records, delivered in one API. I scaled Grow Therapy to a $3B valuation; my cofounder built One Medical's first AI agents, now used by millions of patients. Four weeks in, we already have ten signed customers and 7-figure year-one revenue across platform and usage fees. Every new agentic use case across industries like legal, clinical trials, consumer health, insurance, needs a complete medical record, and today that still means faxes and phone calls. Hubble fixes that with voice and browser agents that reach the providers APIs can't, in a market worth $45B just in the verticals we've mapped so far.
