Customer reviews

"Our front desk used to miss calls constantly during patient hours. Since switching to fonio, every call is answered 24/7, appointments are booked automatically, and our staff can actually focus on patients in the room."

Dr. Amanda Reyes

"I used to lose jobs because I couldn't answer the phone on a job site. fonio handles every inbound call, qualifies the lead, and texts me a summary. I've closed three new clients this month I would have missed."

Owner, Plumbing & Drain Services

My front desk was overwhelmed with booking calls. I set up fonio in less than 20 minutes and now it handles all appointment scheduling while my team focuses on clients. No more voicemails, no more missed bookings."

"I'm a one-person agency and I can't always pick up. fonio qualifies every caller, captures their details, and books showings directly into my calendar. It's like having a full-time receptionist at a fraction of the cost."

Is the data stored in the EU?

Our servers are located in Nuremberg, Germany. Our company headquarters is located in Austria.

Where and how is Fonio developed?

We are one of the few providers of AI phone assistants in Europe that develops its own orchestration layer. This allows us to ensure that all data remains with us. That's what makes fonio special, since most other providers typically white-label U.S. services.

How quickly can I get the phone assistant up and running?

The implementation time depends on the effort required to integrate the system into your existing systems. The AI can be set up in just a few minutes and is ready for use right away.

What if the AI makes mistakes?

Our AI makes decisions based on existing data, which virtually eliminates errors. If the AI is still unable to resolve a situation, it can schedule a callback or transfer the call to a human agent, if desired.
