Vienna-based fonio.ai, an AI platform focused on customer communication for small and medium-sized businesses, has raised $17 million in a seed funding round at a $140 million valuation. Total funding now stands at over $20 million, as Vestbee was informed.
- Founded in 2024 by Daniel Keinrath and Matthias Gruber, fonio.ai develops AI-powered voice agents designed to handle high volumes of business phone interactions.
- The system answers inbound and outbound calls, processes speech in real time, and manages full conversations using technologies such as advanced turn detection, emotion-aware response modeling, and live integrations with business tools including calendars and CRM systems. When necessary, the platform can escalate calls to human agents or schedule follow-ups.
- Companies integrate fonio.ai with either a dedicated or existing phone line, configure call-handling rules, and allow the system to autonomously manage customer inquiries, appointment booking, support requests, and lead qualification.
- The product is also expanding beyond voice, with WhatsApp already supported and additional messaging and email channels in development.
Details of the deal
- The round was led by 20VC, with participation from existing investors as well as founders and executives from Synthesia, HubSpot, and Revolut.
“Every small and mid-sized business knows the cost of a missed call. What Daniel, Matthias and the team are building next is the AI-first operating system for SMBs: one platform that handles communication across every channel and replaces the patchwork of tools these businesses are forced to stitch together today. The traction so far has been remarkable, and we believe they're the absolute best team to build the category-defining company in this space," explains Paul Bonnet, General Partner at 20VC.
- The new funding will be used to accelerate international expansion and further product development. This includes building an omnichannel communication layer that extends beyond voice, as well as developing AI-native tools such as a proprietary CRM and calendar system.
- The company also plans to scale its engineering and commercial teams while expanding its presence across key global markets.
