fonio

fonio builds AI agents that handle customer communication for small and medium businesses. Our phone agent answers calls like a human. It qualifies callers, routes them to the right person, books appointments, and plugs into the tools you already run on. Then WhatsApp, webchat, email and a full PBX setup. One system for every channel your customers use to reach you. Over 10,000 businesses run on fonio. Why join us We give people real ownership. You own your area, you make the decisions in it, and you don't wait for permission. We communicate directly. Feedback goes both ways, mistakes get owned, and nothing important goes unsaid. And whatever you need to do your best work, you get: equity, equipment, lunch and dinner, a monthly learning budget. 50+ open roles across engineering, product, sales and marketing.
