Adonis vs Penguin Ai

Adonis sells to provider revenue cycle teams chasing denial and underpayment recovery, and raised a $40M Series C. MedCity's March 2026 coverage names Mount Sinai Health System, Baptist Health South Florida, AdventHealth and ApolloMD as customers. A hospital revenue cycle VP who wants customer references gets them here, and Penguin Ai trails on that point, since no customer appears on its homepage or about page.

Penguin Ai is a payer-and-provider platform founded in 2024, with a $29.7M round announced in September 2025. Intelligent UM does prior authorization and appeals review for payers, HCC Coding and Risk Adjustment handles coding, and Intelligent RCM covers pre-submission review and denial recovery. It lists Epic FHIR and Cerner, plus HIPAA and SOC 2 with the SOC 2 type not stated. The vendor says 96% accuracy across deployed AI Workers and cites no study. A health plan utilization management lead is the natural buyer, and Adonis's homepage and partner page describe no prior authorization product.
