fonio

fonio is an AI communication platform for small and medium-sized businesses, founded in 2024 and headquartered in Vienna, Austria. Its AI Phone Assistant answers every call around the clock, books appointments automatically, qualifies leads and handles routine inquiries. The system automates more than 2 million calls per month for over 9,500 customers across nine markets. The company also describes its automated CRM system as the first fully automated CRM in the world, which it is currently building.

The work spans AI voice and phone agents, natural language understanding, conversational AI, speech technology and CRM automation. Marketing-facing engineering sits against measurable reach: a product deployed across nine markets and appointment-based and lead-generation verticals where call handling is the primary growth channel. The company employs roughly 50 people.

fonio describes an ownership-oriented culture with few meetings, direct feedback and a fast shipping cadence. Many team members are former founders, and some have scaled products at companies such as Canva. The CTO began building software at the age of 14; the CEO exited his previous ad-tech startup in 2024.
