a16z backs Prosper AI with $30M as healthcare providers seek fewer admin tools

Prosper AI has closed a $30 million Series A round led by Andreessen Horowitz (a16z), backing a Spanish‑founded company that says it has grown revenue fivefold in the past six months and now supports more than 150,000 healthcare providers through an AI‑powered platform that manages the entire patient journey. The financing round also included participation from Base10, with continued support from Emergence Capital, Y Combinator and Company Ventures. Prosper AI says it powers more than $1.3 billion in patient care, has added over 40 healthcare organisations as customers in the last six months, and targets reductions in administrative costs of more than 40%.

“Healthcare providers don't want separate tools for scheduling, insurance verification, and billing,” said Xavier de Gracia, Co‑Founder and Co‑CEO of Prosper AI. “They want a single platform capable of managing the workflows that determine whether care happens and whether providers ultimately get paid. That's what we've built, and it's why providers, health systems, and healthcare technology companies are choosing Prosper AI.”

Context and product details

Prosper AI positions itself as an end‑to‑end patient operations platform that moves beyond first‑generation healthcare AI solutions that focused narrowly on scheduling. Its platform answers patient calls, schedules appointments directly in electronic health records (EHRs), verifies insurance benefits, automates patient billing and contacts insurers by phone when additional information is needed. By combining these capabilities, the company says it manages both patient and payer workflows “from appointment request through reimbursement.”

The startup highlights a broader problem in the healthcare sector: fragmented administrative processes across disconnected teams and point solutions that it estimates generate roughly $450 billion in administrative waste and make care more costly and opaque for patients. Prosper AI’s automated workflows are intended to reduce friction across the pre‑ and post‑care lifecycle, giving patients clearer visibility into coverage and financial responsibility before care is delivered and helping providers improve cash flow and collections.

• Funding: $30 million Series A led by Andreessen Horowitz; participation from Base10; continued support from Emergence Capital, Y Combinator and Company Ventures.
• Growth metrics: 5x revenue increase in six months; more than 150,000 healthcare providers on platform; supports over $1.3 billion in patient care; added 40+ healthcare organisations in six months.
• Claims: administrative cost reductions of +40%; single platform managing scheduling, insurance verification, billing, and insurer outreach.

Investor views and outlook

Jay Rughani, Partner at Andreessen Horowitz, framed the investment around Prosper AI’s ambition to remove administrative friction: “Prosper AI stood out because of the scope of their ambition: they want to eliminate every administrative friction point between a patient and the care they need. What convinced us was the pattern we kept hearing from customers — providers would deploy Prosper AI for scheduling, then quickly ask them to take on insurance verification, then billing, and so on. That pull‑through only happens when your technology can consistently guide patients through the care journey end‑to‑end.”

Adeyemi Ajao, Co‑founder and Managing Partner at Base10 Partners, added: “Prosper AI is leveraging agentic AI to transform the way provider groups and hospitals engage with patients, driving not only savings, but increased revenue and better patient experience.”

Prosper AI says it will use the new capital to expand engineering and customer‑facing teams, deepen integrations across the largest EHR platforms and accelerate adoption across provider groups and health systems — a push aimed at turning early wins in scheduling into a platform that handles the full financial and operational lifecycle of outpatient care.
