Claim Cipher Insurers use algorithms to deny claims. We built a self-improving agent that learns each insurer's hidden behavior, catches wrongful denials, and fights back with evidence-based appeals, without ever showing patient data to the AI. Built at the MongoDB Harness Engineering & Model Wrangling Hackathon, Saturday Sept 26, 2026. Billing operations only: no diagnosis, no treatment, no medical advice. All data is synthetic.
