Prosper AI raised $5M seed to scale healthcare-focused voice AI agents for admin workflows.

Prosper AI, launched in 2023 by MIT and Harvard alumni, just closed a $5 million seed round led by Emergence Capital with support from Y Combinator, CRV, and Company Ventures. The funding will accelerate its voice AI platform, which connects deeply with EHR systems to automate tasks like scheduling, billing, benefit checks, and prior authorizations.

The platform is live across dozens of healthcare organizations — including Providence-affiliated hospitals, large billing companies, pharmaceutical hubs, and EHR providers — enabling hundreds of thousands of automated calls and driving a fourfold revenue jump since Q2 2025. The company now plans to expand its AI agent capabilities beyond voice, such as fax reading and API-based actions in EHRs.

Key Points:

  • Raised $5M seed funding led by Emergence Capital.

  • Integrates with EHRs to automate scheduling, billing, benefits, prior auths.

  • Already handling hundreds of thousands of calls across major healthcare firms.

  • Revenue has quadrupled since Q2 2025 amid rapid platform adoption.

Takeaway: Prosper AI’s traction shows that specialized voice AI agents are finally breaking through in healthcare operations — boosting efficiency, handling real call volumes, and expanding beyond voice into broader administrative automation.

PatientSync has teamed up with Telnyx to power its voice engagements with AI, aiming to transform patient communication in healthcare. The integration brings ultra‑low‑latency voice infrastructure and smooth AI orchestration, delivering always‑on conversational support that blends into clinical workflows naturally.

This system supports both inbound and outbound calls, automating routine tasks like scheduling, reminders, and billing. Built on a private global network, it helps healthcare providers reduce call‑center pressure, improve response times, and maintain consistent, compliant patient experiences around the clock.

Key Points:

  • PatientSync integrates Telnyx’s AI‑powered voice infrastructure.

  • Built on private global network for ultra‑low‑latency calls.

  • Automates inbound and outbound patient interactions securely.

  • Offers scalable, compliant, and human‑like voice experiences.

Takeaway: The most important insight: by combining PatientSync’s engagement platform with Telnyx’s AI voice stack, healthcare systems can automate high‑volume patient calls in real time—cutting staff workload while delivering consistent, responsive, and always‑available service across the board.

Researchers at the University of Maryland have developed VoiceSecure, an AI-powered system that shields personal voice data from automated surveillance.

The tool alters speech signals so that conversations remain clear to humans but unreadable to machines, blocking AI models from extracting biometric or emotional information. Operating directly at the microphone level, VoiceSecure prevents voice data from being intercepted or cloned before it reaches communication platforms.

Unlike traditional encryption or noise-based masking, the system uses psychoacoustic principles and reinforcement learning to hide machine-recognizable patterns while preserving natural sound for human listeners.

Key Points:

  • Developed by Nirupam Roy’s team at the University of Maryland

  • Obscures AI-detectable features while keeping speech intelligible

  • Works at firmware level—no cooperation needed from apps or devices

  • Offers customizable privacy controls and minimal audio degradation

Takeaway: VoiceSecure demonstrates how AI can defend against AI—protecting users’ biometric privacy by exploiting the gap between what humans hear and what machines detect.

Voice AI is rapidly becoming the next major driver of enterprise growth.

In this guest post, Praveen Rangnath, CMO of Deepgram, outlines how businesses are shifting from outdated IVR systems to adaptive, autonomous Agentic AI that understands context, emotion, and intent in real time. A case study of a major U.S. health insurer shows how AI-powered transcription and live assistance cut agent burnout and boosted customer satisfaction.

To be enterprise-ready, voice AI must operate at human speed, handle industry-specific language, and integrate seamlessly across systems—laying the groundwork for the next wave of voice-to-voice AI.

Key Points:

  • Voice AI evolving from IVR to context-aware Agentic AI

  • Proven gains in efficiency and satisfaction for early adopters

  • Requires human-level accuracy, speed, and secure deployment

  • Sets stage for voice-to-voice AI understanding emotion and tone

Takeaway: Voice AI is becoming a core enterprise advantage—turning every conversation into data-driven insight and operational efficiency.
