Trellis builds and deploys self-improving AI agents that automate healthcare document intake, prior authorizations, appeals, medical referral classification, chart-note understanding, and contract and reimbursement searches. Its systems support patients in all fifty states. The company is a spinout from Stanford AI Lab and is backed by leading investors.
