AI-native psychiatry, built for scale and covered by insurance

Founders

YC S21

Hiring Pitch

We’re rebuilding psychiatry from the ground up—AI-native, insurance-covered, and engineered to scale.

Legion Health is a high-quality psychiatry network where patients get care from licensed clinicians, fast and affordably. Under the hood, our LLM agents and orchestration layer automate operations, reduce admin, and enable truly great care.

Most startups bolt AI onto broken workflows. We’re replacing the workflows—and the system underneath.

If you’ve ever wanted to use AI to actually fix something that matters, this is your shot.

We are revolutionizing telepsychiatry through a core AI infrastructure that enables a vastly improved patient experience and quality of mental health care. We are actively improving our services in ingesting, chunking, embedding, caching, and searching to achieve this goal. Our technical goals include:

  • Enhanced processing: Implement robust data structures and caching mechanisms to handle increasing volumes of language data spanning every facet of patients’ care while minimizing latency and maximizing system responsiveness.
  • System scalability: Ensure our systems can scale effectively to support growth from one million to hundreds of millions of data points.
  • Securing sensitive data: Uphold the highest standards of data security and privacy in compliance with HIPAA guidelines.
