fonio.ai

Fonio.ai is a Vienna-based technology company specializing in AI-powered customer communication solutions. Founded in the autumn of 2024 by Daniel Keinrath and Matthias Gruber, the company aims to modernize phone-based customer service. Keinrath, a serial entrepreneur who previously founded the influencer startup GetNano, conceived the idea for fonio.ai after recognizing the clunky nature of existing voice AI, particularly in European languages. He validated the business concept by pre-selling the non-existent product after generating leads through a simple landing page and ad spend.

The company provides a cloud-based platform that enables businesses of all sizes to create and deploy a customized AI phone assistant in minutes, without requiring IT or programming skills. The system is designed to handle incoming calls 24/7, offering natural, human-like conversations that can understand context and emotion. Key features include automated appointment scheduling with calendar integration, call transcription, order taking, and intelligent call routing to human employees when necessary. The platform integrates with existing CRM systems and databases to provide accurate, real-time information during calls.

Fonio.ai operates on a pay-per-use business model, charging clients on a per-minute basis for the time the AI is actively on a call. This model eliminates idle-time costs associated with human agents. The company primarily targets the German-speaking (DACH) market, with plans to expand into other European countries. In December 2025, fonio.ai secured €3 million in an angel funding round from prominent investors to fuel its European expansion and product development. The company has demonstrated significant growth, acquiring over 1,700 customers within its first ten months.
