Ovianta

Ovianta automates patient communication for clinics and hospitals in Spain. The Barcelona-based company deploys voice agents to handle scheduling, reminders, and follow-ups - allowing clinic staff to focus on patient care and improving efficiency. Operating across Spain's linguistically diverse market, Ovianta needed voice agents that could speak with the right regional accent and tone for each clinic's patient base.

In 2025, Ovianta adopted ElevenAgents to power outbound patient follow-up. When a clinic provides a treatment proposal, Ovianta's voice agents automatically follow up to answer questions, address concerns, and reconnect patients with the clinic team.

The challenge

When patients receive a treatment proposal, many take time to decide or forget to follow up. These lost opportunities represent unrealized revenue for clinics and missed care for patients.

Manual follow-up calls fall to the bottom of the priority list when staff are stretched thin managing appointments and in-person care. In a market where patients expect to be addressed in their local language or accent, generic-sounding automation risks undermining trust before the conversation starts.

Why ElevenLabs

Ovianta needed high-quality Spanish voices with a natural peninsular accent - professional and calm for healthcare settings. ElevenLabs stood out for voice quality and the flexibility to customize tone and pacing for sensitive patient conversations.

For healthcare compliance, ElevenLabs offers HIPAA eligibility and Zero Retention Mode - ensuring patient data is not stored or used for model training. Combined with GDPR compliance and EU data residency, this gave Ovianta the security foundation required for sensitive patient communication.

The integration took weeks, not months. As usage scaled, the ElevenLabs team supported Ovianta in handling increasing call volumes.

"With ElevenLabs, we bring empathy to every automated call. As Ovianta grows 20% month-over-month, their voice quality and reliability help us scale without compromising the patient experience clinics depend on."
