Fonoa

Overview

Fonoa is an enterprise-grade financial technology platform built to automate global tax workflows and indirect tax compliance loops for the digital economy. The application operates via a unified API architecture that connects multi-tenant business systems directly to official state tax portals, enabling continuous real-time verification and transaction handling. By executing instant tax ID validation, multi-jurisdiction rate calculations, and localized e-invoicing compliance across over 100 countries, it eliminates structural compliance overhead for fast-scaling platforms. Backed by premier venture groups and incorporating advanced AI tax agents, Fonoa mitigates operational audit vulnerabilities for distributed multinational enterprises.

Founder story

Fonoa was founded in 2018 by Davor Tremac (CEO), Filip Sturman (COO), and Ivan Ivankovic in Zagreb, Croatia. Drawing from their collective experience as senior regional operational executives at Uber, the founders experienced first-hand the massive operational hurdles of manually managing country-by-country digital transaction taxes. They engineered an API-first framework to eliminate legacy system drops, subsequently expanding administrative headquarters to Dublin, Ireland, to support global enterprise scaling.
