Prosper AI raises $5M for voice AI agents automating 50-70% of healthcare calls

Prosper AI raises $5M to put voice agents to work in healthcare operations

Prosper AI has raised $5 million in seed funding to deploy voice-enabled AI agents across front- and back-office workflows in healthcare. The round was led by Emergence Capital with participation from Y Combinator, CRV and Company Ventures.

The company builds voice agents that hold human-like phone conversations with patients and insurance companies. Agents are grounded in each organization's data with guardrails and handle tasks such as patient scheduling, billing, benefits verification and prior authorizations.

Why this matters for healthcare leaders

Administrative overhead continues to squeeze margins and staff capacity. Hospitals shoulder more than 40% of total expenses from administration, with an estimated $40 billion tied to billing alone.

Prosper reports automating 50% to 70% of inbound calls for customers. That level of automation can ease call center load, shorten wait times and improve patient satisfaction without adding headcount.

What Prosper AI's agents do today

• Patient-facing: automated call scheduling, billing inquiries and follow-ups
• Payer-facing: benefits verification, prior authorizations and claims follow-ups
• IVR handling: 99% accuracy moving through phone menus to extract required information
• Operations: skip phone trees, wait on hold and speak directly with insurance agents
• Integrations: connect with practice management software and take action in EHRs; can also read faxes and work with third-party systems

"Our mission is to unlock universal access to care by empowering healthcare organizations to achieve unprecedented efficiency with AI agents," said co-founder Xavier de Gracia.

"The voice AI agents speak like humans and can speak to patients about complex conversations to deep integrations with practice management software," he added. "When calling insurance companies, we skip phone trees, wait on hold and speak with insurance agents on the phone to get the right information."

Traction and team

Prosper AI serves 15 customers representing more than 200,000 providers. Named customers include Synergy Health Associates (11 locations in Texas), a hospital that is part of Providence, and publicly traded Firstsource.

The company employs 15 people today and plans to expand to 25+ this year. Funding will support hiring in engineering, machine learning and sales account executive roles.

How to evaluate voice AI for your organization

• Start with high-volume phone workflows: eligibility checks, prior auth status, claims follow-ups and routine scheduling.
• Measure a baseline: call volumes, average handle time, abandonment rates, first-call resolution and patient satisfaction.
• Pilot in a controlled slice: one specialty, one payer line or a defined scheduling queue with clear success criteria.
• Insist on PHI safeguards: HIPAA-compliant data handling, BAAs, audit logs and clear retention policies.
• Check IVR performance: accuracy, time-to-agent and success rates by payer and line type.
• Confirm integrations: EHR, practice management, ticketing, phone systems and fax ingestion if relevant.
• Design handoffs: graceful escalation to human agents and clear documentation for staff.
• Track outcomes weekly: automation rate by call type, error rates, escalations and workflow bottlenecks.

What's next

Prosper aims to extend from voice-only to full administrative workflows that include fax intake, third-party connections and direct actions in EHRs. As de Gracia put it, "The future is AI workers handling administrative tasks end-to-end."
