Prosper AI (getprosper.ai), a New York-based provider of AI phone agents for healthcare, has raised $30M in Series A funding led by Andreessen Horowitz. The platform deploys voice AI agents that handle both patient-facing calls such as scheduling, intake, and billing as well as payor interactions including benefits verification, prior authorizations, and claims follow-up. The capital will scale deployments across larger health systems and EHR platforms.
Voice AI Targets $450B Admin Burden
The timing comes amid a surge in funding for healthcare voice AI. Infinitus Systems raised over $102M total including a $51.5M Series C, while Assort Health secured $102M and SuperDial closed a $15M Series A in June 2025. Prosper AI's approach addresses both inbound patient calls and outbound payor calls on a single platform, unlike competitors that focus on only one side of the workflow.
$450B Crisis Drives AI Adoption
Healthcare administrative costs represent a $450B burden in the U.S., with administrators growing nearly eight times faster than physicians. Workforce shortages project a 10M health worker gap by 2030, and current solutions require multiple vendors for scheduling, verification, and billing. Practices report 2 hours of documentation per hour of patient care.
End-to-End Platform Replaces Multiple Vendors
Prosper AI built agents covering the full patient journey from scheduling and reminders to benefits verification and denial follow-up, integrating with over 80 EHR systems. It navigates IVR systems and payor portals directly when APIs are unavailable, achieving 99% accuracy and writing results back into records. This contrasts with patient-only tools like Assort Health or payor-only platforms like SuperDial and Infinitus.
"Healthcare providers don't want separate tools for scheduling, insurance verification, and billing." — Xavier de Gracia, co-CEO
a16z Backs AI Workforce Vision
Andreessen Horowitz led the round, with partner Jay Rughani joining the board. The firm previously backed Emergence Capital's $5M seed. a16z cited the land-and-expand pattern where customers start with scheduling and expand to verification and billing, signaling strong product-market fit for an end-to-end solution.
Market Expands 18x by 2034
The AI voice agents market in healthcare stands at $650M in 2026 and is projected to reach $11.57B by 2034 at a 37.9% CAGR. per Towards Healthcare Structural drivers include payer complexity, physician burnout, and 72% patient acceptance of voice AI for routine tasks. Total funding across peers now exceeds $500M.
MIT-Harvard Founders Bring Domain Depth
Co-founders Xavier de Gracia (MIT, Bain & Company, prior call center operations at Handy) and Josep Mingot (Harvard, MIT CSAIL researcher, product lead at CoverWallet) met while studying in Boston. Their backgrounds in operations and insurance position the company to tackle combinatorial complexity across locations, appointment types, and insurance plans.
Rapid Traction Signals Category Leadership
The company now serves 60+ organizations managing $1.3 billion in patient care, with revenue growing 5x in six months. Enterprise integrations include athenahealth, ImagineSoftware, ModMed, and Veradigm. Case studies show 50% call containment and 40% cost reductions at multi-location practices.
