About Cesara
Summary
Cesara builds AI agents that help health system billing teams find and recover underpayments from insurers. The platform ingests payer contracts, claims, and remittance data to answer contract and payment questions in seconds, replacing work that would otherwise take billing staff hours or months. When a claim is paid below the contracted rate, Cesara drafts the reconsideration request, citing the specific contract clause and dollar discrepancy.
Go-to-market
Health system revenue cycle and billing teams are the buyers. The product connects to systems they already use, suggesting a sales-led motion into hospital and ambulatory surgery center finance departments.
