Overview
Fonoa is an API-first global indirect tax automation platform whose modules cover the full lifecycle: tax ID validation, real-time tax determination, e-invoicing and digital tax reporting, and returns. It validates tax IDs across 100+ countries, determines VAT, GST and sales tax across 190+ jurisdictions, and powers compliant e-invoicing and real-time reporting for both AR and AP through a single integration.
The platform is designed for digital-first, high-volume businesses operating across many countries, processing more than a billion transactions annually. Its developer-oriented APIs let companies embed determination, validation and e-invoicing into their own systems and ERPs rather than relying on packaged connectors alone.
Founded in Dublin in 2019 by Uber alumni Davor Tremac, Filip Sturman and Ivan Ivankovic, Fonoa is headquartered in Dublin, Ireland. It has raised significant venture funding (investors include Coatue, Eurazeo, Forestay and others) and in 2026 announced an acquisition of PwC's tax platform alongside a $110M raise.
