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.
What You’ll Do
- Build and optimize core research infrastructure: evaluation pipelines, agent workflows, hallucination detectors, coding benchmarks, and research→production integrations.
- Design, implement, and scale agentic systems across backend, frontend, and model integrations, collaborating closely with research and co-founders.
- Own reliability, observability, and performance across agents (logging, tracing, instrumentation, safety checks).
- Ship research-proven features into production within 7 days, end-to-end.
