We’re Building the Most Impactful Healthcare Company on Earth

We believe that access to a great doctor is a basic human right. Today, that’s not a reality. Delays, misdiagnoses, administrative chaos, and burnout plague the system.

One Human, One Doctor. We build AI teammates that augment clinicians — scribes, nurses, receptionists, translators — all powered by our own world‑class models and deployed in real‑world care.

450+ organizations signed 16 months

AI agents cut admin by ~2.8 hours daily and reduce onboarding 85%.

5M+ Clinical Tasks completed to date, serving 36+ specialties.

Raised $25M from YC, Eric Yuan, Amity, Semper Virens

Patented AI architecture (Med Con-1)
outperforms GPT-4.5, Gemini, Claude on clinical reasoning tasks
