What is fonio ?

fonio is an AI phone assistant from Vienna that grew up in the German-speaking market and is now expanding into other European markets, the US, and the UK. You can build your own phone agent in just a few minutes to answer calls, understand the caller's needs, and either forward the call, leave a note, or book an appointment, depending on the situation. The focus is clearly on natural-sounding German.

‍

The target audience includes small businesses and freelancers: tradespeople, real estate agents, medical practices, and recruiters. For them, it’s crucial that the setup requires no technical expertise and that the assistant doesn't sound like a poorly translated recording. The startup is growing rapidly, going from 1,200 customers to more than 7,000 today.

‍

Compared to Placetel, fonio lacks an integrated phone system, and unlike smao, it doesn't rely on US-based models. However, fonio is one of the fastest ways to get a great-sounding German phone agent. As a young startup, the roadmap is still evolving, and some features are brand new.

‍

The right choice for small German-speaking businesses that want a natural-sounding phone assistant quickly. If you need a full-featured phone system or strict data sovereignty, you should look at Placetel or smao.
