Detailed Review
fonio is organised around trades rather than around developers. The site has pages for medical practices, law firms, tax advisers, estate agents, car dealerships and restaurants, and the setup is a hosted assistant that you configure with your opening hours and company information.
The contracting company is fonio GmbH in Vienna, with Daniel Keinrath and Matthias Gruber named as managing directors in the imprint.
Plans by call volume
The phone assistant is sold in three plans measured in minutes. Solo covers 1,000 minutes, one phone number and no concurrent calls. Team covers 3,600 minutes, three concurrent calls and a dedicated SIP trunk, and Scale starts at 6,000 minutes with custom concurrency and a custom voice.
Prices exclude VAT, and annual billing lowers the monthly figure by roughly a sixth to a fifth.
Booking and knowledge
The assistant checks a connected calendar, accepts appointments and schedules them. It can read company information from your website, and a self-learning knowledge base lets the agent store answers it worked out itself.
The same account can add a WhatsApp bot and a website chatbot, each with their own plan ladder.
Outbound and data retention
Outbound calls and campaigns are listed at carrier cost on top of the plan, and each outgoing call deducts minutes from the allowance. Zero data retention appears only in the Scale tier.
Limitations to Consider
The pages we checked do not say where audio is processed, and zero data retention is limited to the Scale plan. The Solo plan has no concurrent calls, so a second caller meets a busy line. Outbound minutes carry carrier charges on top. For custom conversation logic, Famulor or telli offer deeper builders.
Who Should Use fonio
Small businesses and professional practices in German-speaking and other European markets that want a phone assistant on a monthly plan.
