Vocca

Vocca builds AI voice agents for healthcare. Founded in 2024, the company develops proprietary conversational AI that answers patient phone calls, schedules and reschedules appointments, and operates continuously across phone, SMS and WhatsApp. The system is trained on medical vocabulary and on the specific workflows of each medical specialty. It resolves more than 80% of requests without hold time or human intervention and manages more than 100 simultaneous calls.

The technical work spans conversational AI, speech recognition and telephony, natural language understanding, and multichannel automation. Deployment in a regulated, vocabulary-heavy domain places particular demands on accuracy, workflow modelling and integration with medical practice operations.

By its own account, Vocca serves more than 3,500 practitioners and has handled over 4 million calls. Reported outcomes include up to 70% fewer missed appointments and three or more hours saved per medical secretary each day. The company targets 10,000+ practitioners by 2026 and plans to triple its team over the same period, with operations in France and the United States. It raised a $5.5M seed round.
