Prosper AI

Voice agents that handle patient and payer phone calls

Our take

Prosper AI builds voice agents for healthcare phone work in both directions: answering patient calls (scheduling, billing questions, refills, routing) and placing outbound calls to payers (benefit verification, prior auth initiation and tracking, claims follow-up). Agents write back to the EHR in real time, navigate payer IVR trees, and sit on hold so staff do not. Buyers are outpatient medical groups, health systems, and RCM companies that want to shrink call center and back office phone labor.

The company was founded in 2023 by Xavier de Gracia and Josep Mingot, went through Y Combinator, and raised a $5M seed from Emergence Capital before a $30M Series A led by Andreessen Horowitz in June 2026. Prosper reports 5x revenue growth since seed, more than 40 care organization customers, workflows touching 150,000 physicians, and an 80% win rate in competitive evaluations. Named customers include Northeast OB/GYN and Piedmont Plastic Surgery & Dermatology, plus channel partners like Firstsource and Imagine Software. It is SOC 2 Type II and HIPAA compliant with on-premise or cloud deployment.

What it does

Answers inbound patient calls and schedules in the EHR
Calls payers for benefit verification and prior auth

Where it's strong

Covers both sides of the phone: inbound patient access and outbound payer calls.
Well capitalized after a $30M a16z Series A, with 40+ care organizations and workflows spanning 150,000 physicians.
Claims half of calls resolved end to end and go-live in about three weeks.

What buyers should weigh

Broad scope across many call types means depth per workflow varies; test your highest-volume call type first.
Named references skew toward specialty outpatient groups, not large health systems.
Rapid growth after a 2023 founding means processes and support are still maturing.
