Healthcare's frontier lab for clinical-grade AI
We build the AI that clinicians trust when it matters most.
The problem we're built to solve
Clinicians spend more time on documentation than on patients. Medical coding errors cost health systems billions. Coding backlogs and denials eat into margins that are already thin. And the specialist expertise a patient needs isn't always in the room when they need it.
General-purpose AI doesn't fix this. It wasn't trained on clinical language, it doesn't hold up under regulatory scrutiny, and it fails quietly in settings where a quiet failure has consequences.
We build for clinical reality instead. Every model we ship is trained on real patient interactions, validated against real outcomes, and stress-tested before it touches a live workflow.
What we build
Everything runs on Symphony, our clinical-grade AI model, delivered through four capabilities: speech-to-text, text generation, medical coding, and an agentic framework for teams building agents that reason and act across clinical workflows.
Symphony ranks #1 on OpenAI's HealthBench Professional, ahead of GPT-5.4 and Claude Opus 4.7. It runs at roughly 2% word error rate on medical speech, validated across 150,000+ medical terms and 14 languages. On automated coding, it leads the next-best system by more than 25 points. More benchmarks.
We don't build in a vacuum. Corti's work is published at NeurIPS, ICML, ICLR, ACL, and npj Digital Medicine, and independently benchmarked against the largest AI labs, not just against ourselves.
Safety isn't a footnote
Every capability ships with HIPAA, GDPR, SOC 2, ISO 27001, and ISO 42001 already built in, along with NHS DSPT/DTAC and EU AI Act coverage where it applies. We treat compliance as infrastructure, not paperwork bolted on after the fact.
Join the mission
We're on a mission to ensure everyone has access to medical expertise, no matter where they are.
