Insurance Billing Lead (backed by Y Combinator, $5M+ ARR, $23M+ raised)

Legion Health is building autonomous medical care, starting with psychiatry. Our AI-native care-delivery platform currently automates 95% of the administrative work required for us to deliver direct patient care. We also recently became the first company ever to receive regulatory authorization to let AI prescribe psychiatric medications, allowing us to not only collapse health care’s admin costs but also its clinical labor costs—entirely shifting this industry’s economics from humans to tokens.

Our technical moat is hard to copy—we combine rich data, production AI, psychiatrists in the loop, and end-to-end care operations to deliver measurably better care to a clinically complex patient population. This has helped us produce 20K+ total visits and $4.2M in ARR in just 2 years (~4× YoY), all while holding ops costs flat and achieving industry-leading patient NPS and retention.

While the last generation of healthcare startups made the existing system slightly more efficient—for example, by moving providers from out-of-network to accepting insurance—Legion is fundamentally rebuilding full-stack care delivery from first principles. With a global TAM of $2.15T and our recent regulatory approval for autonomous prescribing, we plan to 10× in the next year with a national rollout.

The company was founded by three best friends from Princeton University: Yash was the youngest health economist at the Congressional Budget Office with Medicare and Medicaid expertise, Daniel has an extensive background in deep learning and AI from Microsoft, and Arthur is a self-taught engineer and former McKinsey consultant. Legion Health is backed by Y Combinator, Alumni Ventures, and Soma Capital, plus founders from Function Health, Modern Health, Everly Health, Trusted Health, Clipboard Health, PatientPing, Sesame Care, Faire, EasyPost, and fuboTV.

At Legion Health, we believe everyone deserves fast, affordable, and world-class health care, and we’re developing the AI infrastructure to deliver it ourselves at world scale.
