Anterior closed a $40 million financing to scale an AI platform that automates administrative clinical workflows for health plans, the company said. The platform is designed to accelerate prior‑authorization and utilization management processes, promising approvals in minutes rather than weeks and enabling payer staff to reduce manual burdens. Backers framed the round as a bet on cost containment and clinician workflow relief. Buyers and payers will watch validation data for safety, auditability and regulatory compliance as automated decisioning expands in clinical operations.
