Fonoa Raises $110M Series C, Buys PwC Tax Platform

Jan de Vries · 2026-05-29

Fonoa, a Dublin-based AI tax operating system for global businesses, just dropped some huge news. They've raised $110 million in Series C funding and bought Indirect Tax Edge (Edge) from PricewaterhouseCoopers (PwC). This is a big deal for anyone watching the tax tech space. ### The Funding Round The round was led by Headline, with new investors Eurazeo and Forestay Capital joining in. Existing backers like Index Ventures, OMERS, Coatue, and Dawn Capital also participated. That's a lot of confidence in what Fonoa is building.  ### What Fonoa Does Davor Tremac, CEO and co-founder of Fonoa, put it perfectly: "While technology has transformed much of finance, tax systems have remained neglected." He's right. For years, accounting teams have juggled different vendors for tax determination, e-invoicing, and returns—all held together with spreadsheets. It's a mess. Fonoa changes that. They offer a single platform that covers the entire indirect tax lifecycle. Think tax ID validation, real-time tax determination, e-invoicing, and returns. All on one shared data model with one audit trail. Their AI agents monitor obligations, populate returns, catch anomalies, and assemble audit packs in seconds. ### Real-World Impact Fonoa supports tax determination across over 190 jurisdictions, validates tax IDs in more than 100 countries, powers e-invoicing for millions of sellers, and processes over a billion transactions annually. Their clients include Canva, Uber, Netflix, Nebius, and Booking.com. These are companies with massive global footprints that need real-time compliance. ### The Edge Acquisition Edge is an indirect tax compliance system used by global enterprises for VAT/GST reporting, e-filing, data management, and tax analytics. The acquisition fills a critical gap. Enterprise tax teams used to handle upstream processes like tax determination in separate systems from downstream compliance reporting. Now, Fonoa and Edge together cover the whole lifecycle in one data model. ### What This Means Peter Michalowski, Global Indirect Tax Network Leader at PwC, said: "Fonoa is perfectly placed to provide the dedicated expertise, focus, and investment needed to build and scale the Edge platform." Fonoa plans to integrate Edge with its modular tax infrastructure and AI layer. PwC will continue delivering global indirect tax services through Edge as part of Fonoa's system. With this new capital and the Edge acquisition, Fonoa is set to expand its platform to cover the full indirect tax lifecycle. It's a smart move that could reshape how global businesses handle tax compliance. - Fonoa raised $110 million in Series C funding. - They acquired PwC's Indirect Tax Edge platform. - The combined platform covers the entire indirect tax lifecycle. - Clients include Uber, Netflix, and Booking.com. This is one to watch. Tax tech is finally getting the attention it deserves.
