Vocca, a Paris startup building voice AI for medical practices, closed a $20 million Series A last week led by Norrsken VC. Heal Capital, Speedinvest, firstminute capital and several prominent angel investors joined the round, bringing the company's total raised to $25 million since its founding in July 2024.
The funding comes as the two-year-old company reports growth that has surprised even some of its backers. Between late 2025 and October last year, Vocca's customer base swelled from 2,000 to 15,000 practitioners while revenue climbed sevenfold, according to figures Norrsken VC shared alongside the announcement. Those numbers arrive at a moment when healthcare administrative costs remain stubbornly high—Oliver Wyman pegged the figure at roughly 25% of all US healthcare spending in an analysis published early last year—and when nearly half of patient calls to doctors' offices go unanswered during business hours, according to industry studies vendors frequently cite.
Vocca's platform picks up where overworked front-desk staff leave off. The system fields inbound calls at any hour, schedules and reschedules appointments by writing directly into whatever practice-management software a clinic already uses, and handles routine questions in multiple languages. More than 1 million patient conversations now flow through Vocca each month, Norrsken VC said, with the AI resolving about 70% of them without requiring a human to step in. Practices that have been using the system longest are pushing that figure above 85%.
The startup now serves over 1,500 practices spanning more than 20 medical specialties. Its customer roster includes DAG Dental, a 37-location dental group in the United States; Point Vision, which operates 67 ophthalmology centers across France; and Résonance Imagerie, a 60-center imaging network. Last April, Hôpital Fondation Adolphe de Rothschild in Paris became the first French hospital to deploy an AI voice assistant hospitalwide, a milestone the institution highlighted at the time.
CEO Eliott Hoffenberg and CTO Hugo Danet launched Vocca in July 2024. Hoffenberg's background includes running a startup incubator and attending The Wharton School, according to his LinkedIn profile. Danet studied at Télécom Paris through 2022. The company now employs about 40 people split between Paris and New York, with plans to add roughly 40 more by the end of this year. Vocca opened its New York office last September, Hoffenberg noted in a LinkedIn post.
The fresh capital will go toward deeper integrations with scheduling systems, expansion into additional specialties and communication channels, and a more aggressive push into the US market, Norrsken VC said. Vocca already maintains separate production environments and data hosting for American versus European customers to meet HIPAA and GDPR requirements, according to a legal notice the company updated in late September.
"Practices don't ask us about price," Hoffenberg said in a statement. "They ask how fast we can deploy and how we handle their specific cases." That pragmatism may reflect the urgency many clinics feel: answering phones has become a bottleneck rather than a courtesy, and missed calls often mean lost patients.
Vocca operates in a field growing more crowded by the quarter. Hyro announced a partnership with Five9 last May to embed AI agents into health-system call centers. Prosper AI, meanwhile, raised a $30 million Series A from Andreessen Horowitz in June, offering a platform that extends beyond voice to tackle scheduling, insurance verification and billing coordination.
Vocca previously raised $5.5 million in a seed round co-led by Speedinvest and firstminute capital in September 2025. That round drew participation from Kima Ventures, FJ Labs, Sequoia Scout Roxane Varza and angels including the founders of Deel, Jellysmack and Mistral. Notable angels in the new Series A include the founders of Alan and Datadog, though the company did not disclose their individual contributions.
"Patients have been left on hold for too long," Norrsken VC said in a statement accompanying the investment. "We couldn't be more excited to back Eliott, Hugo and the entire Vocca team as they give healthcare more time for what matters." Whether that promise holds will depend on how well voice AI can navigate the messy realities of medical practice—accents, urgent requests, patients who want a human voice on the other end. For now, at least, clinics seem willing to find out.
