What Hubble does

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.

AI-native retrieval engine for medical records

What is your company going to make? Please describe your product and what it does or will do.

Hubble is an AI-native retrieval engine for medical records. We give users one API to get a complete patient record, even from providers whose data isn't available via existing APIs. Our agents use voice and browser automation to fetch records when APIs aren't an option, which is still most of the market. We make it possible for any agentic workflow - clinical trials, insurance, consumer health - to access medical data that today is buried in faxes and phone calls.

Where do you live now, and where would the company be based after YC?

We live in Seattle, WA, USA, and the company will stay based there after YC.

Explain your decision regarding location.

Seattle gives us proximity to major healthcare systems and tech talent. We're already here and it works for building in healthcare IT.

Is this the real Hubble YC application?

No. Y Combinator keeps submitted applications private. This is a reconstruction: the real YC form questions, answered from Hubble's public data (launch notes, founder backgrounds, product description). It shows how a company like Hubble would present itself to YC, not the text they submitted.
