Before Eureka was a company, it was how we ran our own clinic.
We are Zain Memon and Sina Hartung. We started an endocrinology practice, got buried under the same admin every solo doctor knows, and built our way out of it. Real patients, real scale, and zero full-time non-physician staff, because the software did the operating. Eureka is that software, opened up for any doctor who wants the same.

Zain Memon
Co-founder and CEO
Zain built the core infrastructure that lets a single doctor run a full-stack practice without an administrative team. Before Eureka was a product anyone else could use, it was the operating system for our own clinic. He is one of the people behind the medical AI system that outscored OpenAI, Google, and the other major labs on the US Medical Licensing Exam.

Sina Hartung
Co-founder and Chief Operating Officer
Sina studied at Harvard Medical School and ran the operations of our endocrinology practice on this exact platform before Eureka had its first customer outside the founding team. She built the workflows, tested the limits, and made the calls that shaped how the system behaves inside a real practice. Every workflow in Eureka is shaped by how a real practice actually runs, because she built it from inside ours.
We ran the experiment on ourselves first.
Everything we ask a doctor to trust, we tested in our own practice before we offered it to anyone.
We ran our own clinic at real scale with zero full-time non-physician staff.
Before we sold Eureka to a single other doctor, we ran our own endocrinology practice on it. We grew it to real scale, on a growth trajectory most practices reach only by building a full administrative layer. Every appointment, every intake form, every chart note, every payment ran through the system, and we were the only people in the room. That was the proof, to us, that it actually worked.
We built a medical AI system that outscored the major labs on the USMLE.
We built our own medical AI system and put it through the US Medical Licensing Exam, where it outscored the leading systems from OpenAI, Google, and the other major labs. It is the same system that runs underneath the AI in your clinic. The AI drafts and routes. You decide, you sign every note, and you approve every order. That line holds.
Backed by institutions that look closely before they commit.
Eureka is backed by Y Combinator and Khosla Ventures. We mention it because these are organizations that examined what we built before putting their name next to it. What matters is that people who hold a high bar looked closely at the work and decided it was real.
We are building the company we wish had existed.
When we were running our own clinic, this is the thing we kept wishing for. Now it exists, and it is open to you. The rest of the site shows you exactly how it works.
