Crosby Health
AI-generated clinical appeals for denied claims
Our take
Crosby Health automates clinical appeals for denied claims. Its clinical language model, Apollo, reads denial letters and up to 300 pages of medical records, locates the evidence of medical necessity, drafts an appeal letter aligned to clinical and legal guidelines, then submits it through a single unified channel instead of dozens of payer portals and fax lines, tracking each appeal through to a decision. The tagline is blunt: appeal every denial, no balance too small.
Founded in 2022 in New York by Louis Ciano and Rishi Gowda, Crosby raised $2.2M led by Amplo Ventures in 2024 and remains a small team of about 15. EmpowerMe Wellness, its publicly cited customer, reports appealing denials 300% faster since adopting Apollo. The company claims strong benchmark performance for Apollo on medical licensing exams. The buyer math is simple: hospitals spend billions overturning denials that should never have been issued, and half of appealed denials get overturned. Crosby is a bet on a very young vendor, but the downside is limited because it monetizes claims you were likely writing off anyway.
What it does
- Generates clinical appeal letters for denied claims with AI
- Apollo clinical LLM reads up to 300 pages of documentation
- Finds medical necessity evidence inside clinical notes
- Submits appeals through one unified payer submission channel
- Tracks appeal status and payer decisions with notifications
- Supports medical coding review and chart auditing
Where it's strong
- Attacks a problem most providers simply abandon: appealing every denial, including small balances that are uneconomical to work manually.
- Unified payer submission removes the portal-and-fax maze that makes appeals so labor intensive.
- Early users report appealing denials 300% faster than manual processes.
What buyers should weigh
- Very early company: roughly 15 employees, about $3M raised, and only one publicly named customer.
- Appeals-only focus means it recovers lost revenue but does nothing to prevent denials upstream.
- No publicly documented EHR integrations, so verify how clinical documentation actually gets into the platform.
