Aegis

Aegis is a San Francisco healthtech startup (YC X25) that automates the insurance denial appeals process for healthcare providers, hospitals, and medical billing groups. Its AI detects denied claims, pulls supporting records from EHRs and clearinghouses, drafts policy-specific appeal letters, and submits and tracks them through payer portals - helping providers recover revenue that would otherwise go unclaimed because appeals are too slow and costly to file by hand.
