Fonoa offers a modular tax operating system built to manage the full indirect tax lifecycle on a single shared data model and audit trail. Its modules include tax ID validation, real-time tax determination, e-invoicing, and returns, with AI agents that monitor obligations, populate returns, catch anomalies, and assemble audit packs. The company supports tax determination across 190+ jurisdictions, validates tax IDs in 100+ countries, powers e-invoicing for millions of sellers, and processes more than a billion transactions annually. Fonoa was founded by three Uber alumni and counts customers such as Canva, Uber, Netflix, Nebius, and Booking.com. With the $110M Series C and the acquisition of PwC’s Edge platform, Fonoa plans to integrate compliance and filing capabilities, scale engineering resources, and accelerate AI-enabled features toward an autonomous tax operating system.
