fonio.ai builds AI agents and an omnichannel platform to automate customer interactions for businesses that rely heavily on phone communication. The startup’s stack includes technologies for speech recognition, turn detection, emotion recognition, and real-time orchestration designed to let the platform autonomously manage and resolve many customer inquiries. In under two years it has grown to serve more than 7,500 businesses, including Volkswagen, Storebox, and Brita, and currently automates over two million customer calls each month. The company operates across several European markets and Brazil and has recently launched in the U.K. and U.S. fonio.ai plans to expand beyond voice into WhatsApp, email, and chatbots and is developing additional AI-native tools such as a proprietary calendar and a CRM for AI-driven interactions. The company is led by founders Daniel Keinrath and Matthias Gruber and has raised over $20 million to date.
