About Us At Sully.ai, 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.

Our Mission: 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.

Our Traction

• 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 (MedCon-1) outperforms GPT-4.5, Gemini, Claude on clinical reasoning tasks

Sully requires A-players capable of 4 months = 1 year output.
