Prosper AI just closed a $30 million Series A led by Andreessen Horowitz, betting that the future of healthcare administration involves fewer humans sitting on hold and more AI agents doing the dialing.
The round also brought in new investor Base10 alongside follow-on participation from Emergence Capital, Y Combinator, and Company Ventures. Total funding for the company now sits in the range of $35 to $36.6 million, including a $5 million seed round that closed in September 2025.
Here’s the thing about healthcare in the US: an estimated $450 billion gets spent annually on administrative tasks. That’s not surgery, not diagnostics, not anything remotely clinical. It’s scheduling appointments, verifying insurance eligibility, filing prior authorizations, and chasing billing paperwork.
Prosper AI builds voice-based AI agents designed to handle exactly those phone-heavy workflows.
From seed to Series A in nine months
