$9M+ ARR, 10,000+ customers. We got there in under 12 months. We build AI voice agents for small and medium-sized businesses so they never miss a call again and can focus on the work they actually love. Our AI handles every call automatically. But voice is just the start. Our vision: the fully automated AI suite for SMBs. We live ownership. You are end-to-end responsible for your projects and tasks. No politics, few meetings, direct feedback. At fonio you build with the smartest and most ambitious people in the scene. Join one of Europe’s fastest-growing startups – now in Brazil.
Brazil is one of our biggest bets. We are 7 people today, 20 by the end of the year, 100 by mid next year. We are opening our first Brazilian office in Campinas right now.
You are the right hand of Fernando, our Country Manager, and the person who makes this growth actually work: office, people, finance, admin, projects. Fernando sells and leads. You make sure everything around it runs, and you see problems before they hit the team. Nothing gets built at this pace without you – you are one of the most important hires we make in Brazil this year.
This is not an assistant role. You own your topics end to end, build the processes from scratch and grow into leading them as the team grows.
