Clinical reasoning AI for health plans whose Florence agent automates prior authorization end to end with cited evidence chains and clinician escalation, deployed in payer organizations processing 8M+ prior authorizations per year.

Anterior (founded as Co:Helm) builds a clinical AI reasoning platform for health plans, starting with prior authorization and extending to care management, payment integrity, and risk adjustment. Its Florence agent reviews medical necessity against plan rules with a full chain of reasoning and cited evidence for every micro decision, and always escalates to a clinician when a definitive path to approval is not found, so the AI approves but never denies.

Modular Actions handle intake of clinical documentation, retrieval of missing provider information, eligibility confirmation, and audit validation. Over 40 percent of the team are nurses and physicians, with forward deployed clinicians embedding at customers; in a Geisinger Health Plan deployment cancer care approvals complete in roughly 155 seconds.
