Marek Pawlak
‍Tradesman

"It's just great for us. My phone isn't ringing all the time anymore because fonio now handles my schedule. The AI creates a call summary, so I can finally get some peace and quiet on the construction site without worrying about losing customers while I'm busy working."

Elena Rossi
‍Medical office staff member

fonio really takes a load off our team! The AI handles typical questions about opening hours or prescriptions. "This keeps the lines open for real emergencies, and we can focus on properly caring for patients on-site again."

Lars Sondergaard
Hotel Manager

"Our guests often don't call until the evening, when there are fewer staff members on duty. With fonio, we're now available 24/7 and never miss a booking again. "The setup was extremely quick and works seamlessly."

Anika Varga
‍Property Management

"In the past, when there were technical issues, we were completely unaware if 20 people called at the same time. Now the AI recognizes the call location and sends us a clear list instead of confusing voicemail messages."

Stefan Novak
‍Car dealership

"The biggest advantage for us is the automatic appointment scheduling, because fonio syncs directly with our calendar tool and everything is neatly organized in the system."

Frequently asked questions

Are you really the best AI phone assistant?

Hier sind die Bewertungen unserer Kunden 😉

👉 OMR
👉 Capterra
👉 Trustpilot
👉 Google Reviews

Is the data stored in the EU?

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

Where and how is fonio developed?

We are one of the few providers of AI-powered 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 fonio into your existing systems. The AI can be set up in just a few minutes and is ready to 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 the issue, it can schedule a callback or transfer the call to a human agent, if desired.

Scalable call management with fonio.

Try fonio.ai and see how our AI phone assistant automates your calls to reduce strain on your team – it's simple, efficient, and around the clock.
