Vocca Raises $5.5M to Scale AI Voice Agents for Healthcare Appointment Booking

Vocca, an AI startup founded in 2024, has secured a $5.5 million funding round led by Speedinvest and firstminute capital. The company specializes in automating inbound and outbound calls for healthcare providers, with plans to triple its team and accelerate expansion across the U.S. and Europe. By 2026, Vocca aims to equip more than 10,000 practitioners with its technology.

Phone calls remain the primary communication channel for healthcare providers, with over 70% of medical appointments booked this way, but the system is under strain. Sixty percent of patients hang up if their call is not answered within a minute, while average wait times exceed five minutes. This inefficiency costs healthcare practices an estimated $150 billion annually, while also driving high staff turnover and patient dissatisfaction. Vocca addresses these challenges with a purpose-built AI assistant that operates around the clock, books appointments directly into medical software, and manages complex requests.

The company’s AI voice agents are trained on medical vocabulary and specialty workflows, resolving more than 80% of requests without hold times or human intervention. The platform has already processed over four million calls and is used by more than 2,000 practitioners. In practice, Vocca has saved one multidisciplinary center 11 hours per day per site and increased a hospital’s call response rate from 30% to 100%. On average, the system frees medical secretaries from over three hours of daily administrative work, allowing them to focus on patient care. This shift has led to higher patient satisfaction and up to 70% fewer missed appointments.

“Our mission is to improve access to care for hundreds of thousands of patients while developing specialty-specific workflows for every medical discipline,” said Eliott Hoffenberg, Vocca’s co-founder and CEO. The platform is fully compliant with GDPR, HIPAA, and SOC 2, ensuring both security and patient trust.
