About fonio

We’re fonio.ai. A Vienna-based startup building AI phone assistants that sound like a real person and can handle calls end-to-end.

In the DACH region, 6,000+ small and medium enterprises already use and trust fonio every day. In just 1,5 years, we have grown to become the market leader. We’re currently adding ~€250k ARR per week. After having raised our €3m Seed round in fall of 2025, we are now building the structural backbone of the company for rapid internationalization.

Our vision is to revolutionize how SMEs communicate with their customers using AI. We're looking for motivated, talented team members to join us on this mission.

Small team. Fast pace. Direct communication. We're proving you can build world-class companies from Europe.

Your role

You will own everything operational finance at fonio. As part of the operations team, you will build up an operational finance function that acts as an asset rather than a liability. The processes and structures you build along the way will support fonio's rapid internationalization and growth. We are not looking for someone that does repetitive work, but rather for a person who takes ownership, improves and automates processes and builds the financial foundation for the future successes of fonio.
