RevRecover is an autonomous AI agent that fights insurance claim denials for hospitals. When a claim is denied, TinyFish — our agentic framework — automatically researches the denial reason using real clinical databases like ClinicalTrials.gov, generates a medically-backed appeal letter, and navigates the insurance portal to file it without any human involvement. What takes a billing clerk 47 minutes per claim, RevRecover does in under 2 minutes — at scale, across every denied claim in the queue simultaneously.
