Fonoa raises $110M to expand AI tax platform. 29 May 2026 Key Takeaways * Fonoa has closed a $110 million Series C funding round led by Headline, supported by top-tier firms like Eurazeo, Index Ventures, and Coatue. * Headline led the round with support from new and existing investors. * The company aims to create a unified AI-powered tax operating system. Fonoa has raised a $110 million Series C funding round alongside the high-profile acquisition of Indirect Tax Edge (Edge) from Big Four consultancy firm PricewaterhouseCoopers (PwC). Global venture capital firm Headline led the growth capital round. It also drew backing from new institutional investors Eurazeo and Forestay Capital alongside a powerful contingent of returning investors, including Index Ventures, OMERS, Coatue Management, and Dawn Capital. This massive cash injection and simultaneous asset acquisition position Fonoa to rewrite the rules of international indirect tax, transitioning corporate finance from manual, periodic reporting to completely real-time automation. Solving the fragile, segmented tax stack. Founded in 2019 by three former Uber executives, Davor Tremac, Filip Sturman, and Ivan Ivanković, Fonoa was born directly out of the operational frustrations of managing hyper-growth, borderless digital platforms. While ride-sharing, streaming services, and digital marketplaces scale effortlessly across geographical boundaries, their underlying financial teams are often forced to confront an incredibly complex, fragmented, and antiquated global tax system. "While technology has transformed much of finance, tax systems have remained neglected, leaving accounting teams to manage the same fragmented stack for decades," explained Davor Tremac, CEO and co-founder of Fonoa. "Companies have historically used one vendor for tax ID determination, another for digital e-invoicing, and a third for filing regional returns, with manual spreadsheets desperately holding the pieces together." This patchwork workflow has become completely unsustainable as governments worldwide aggressively clamp down on digital tax evasion. Regulatory bodies are rapidly shifting away from historical, retroactive monthly or quarterly tax reporting. Instead, countries are mandating real-time transaction reporting and automated e-invoicing, meaning tax compliance must now happen at the exact millisecond a consumer hits a "buy" or "book" button. Fusing infrastructure with PwC's Edge. The strategic crown jewel of Fonoa's dual announcement is its acquisition of PwC's Indirect Tax Edge software platform. Used by some of the largest multinationals in the world, Edge is an enterprise-grade compliance application specialising in Value Added Tax (VAT) and Goods and Services Tax (GST) management, automated e-filing, and macro-level tax data analytics. The deal perfectly bridges a historic product gap in the TaxTech landscape. By combining Fonoa's native API infrastructure with the advanced filing capabilities of Edge, Fonoa now hosts a unified, single data model that manages the entire lifecycle of indirect tax. Within this integrated loop, AI agents autonomously track changing tax rules across jurisdictions, actively monitor transaction streams, flag reporting anomalies, and assemble audit packs in seconds. Under the structured terms of the deal, PwC will continue to deliver deep indirect tax consulting and managed services to its global clients using Fonoa's upgraded infrastructure. Explosive transaction volume and global reach. Fonoa's platform is fundamentally optimised for digital-first enterprises. Unlike traditional legacy tax software providers built around slow enterprise resource planning (ERP) batch updates, Fonoa is entirely cloud-native. The efficiency gains are stark, with some enterprise clients reporting up to a 90% reduction in tax calculation latency. Today, Fonoa boasts an established operational footprint that includes the following: * 190+ Jurisdictions: Real-time automated tax determination. * 100+ Countries: Instant, programmatic corporate tax ID validation. * 1 Billion+ Transactions: Safely processed and logged through its architecture annually. This massive scale has turned the startup into the primary compliance engine for a roster of the world's most recognisable digital brands, including Netflix, Uber, Canva, Booking.com, and Nebius. With $110 million in fresh capital, Fonoa plans to aggressively expand its global engineering capacity and integrate more predictive AI models into its core modules. As international tax bodies lean into real-time digital scrutiny, Fonoa is transforming compliance from an ongoing corporate liability into an invisible, fully autonomous utility.

Dublin-registered Fonoa has raised a $110M Series C led by Headline and acquired PwC’s Indirect Tax Edge, betting real-time tax compliance is replacing point tools.

Dublin's AI TaxTech startup Fonoa raises €94.4 million Series C and buys PwC's tax platform. May 29, 2026 Fonoa, a Dublin-based AI tax operating system for global businesses, has raised €94.4 million ($110 million) in Series C funding and acquired Indirect Tax Edge (Edge) from PricewaterhouseCoopers (PwC). The funding round was led by Headline and included participation from new investors Eurazeo and Forestay Capital, alongside existing investors Index Ventures, OMERS, Coatue, and Dawn Capital. Davor Tremac, CEO and co-founder of Fonoa, "While technology has transformed much of finance, tax systems have remained neglected, leaving accounting teams to manage the same fragmented stack for decades: one vendor for determination, another for e-invoicing, a third for returns, with spreadsheets holding it all together. "This model has become unsustainable, especially when you think about it through the lens of companies like Uber or Netflix that have constantly-expanding global footprints and must navigate region-specific tax and compliance requirements. We built Fonoa to keep multinational finance operations able to keep pace with global companies' ambition. By bringing Edge into the platform, we are adding compliance and filing to that foundation, creating the first-ever complete system required for autonomous tax." Founded in 2019 by three Uber alumni, Davor Tremac, Filip Sturman, and Ivan Ivankovi, to help navigate complex, real-time tax requirements as they scale across markets. The company states that its modules cover the full indirect tax lifecycle, including tax ID validation, real-time tax determination, e-invoicing, and returns. All on one shared data model and integration, with one audit trail. Each added capability makes the others stronger. Agents monitor obligations, populate returns, catch anomalies and assemble audit packs in seconds. Fonoa claims that it 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. The company notes that its platform is designed for real-time compliance across digital and cross-border business models, and adds that this sets it apart from legacy providers built around ERP integrations and batch reporting. Notable clients include Canva, Uber, Netflix, Nebius, and Booking.com Edge is an indirect tax compliance system used by global enterprises across industries to manage VAT/GST compliance reporting, e-filing, transactional data management, and tax analytics. The acquisition seeks to bridge a long-standing gap in indirect tax technology. According to Fonoa, enterprise tax teams currently handle upstream processes such as tax determination and e-invoicing in separate systems from downstream compliance reporting and filing. Together, Fonoa and Edge now encompass the entire indirect tax lifecycle within a single data model: from tax ID validation and real-time determination to e-invoicing and return submission. "Fonoa is perfectly placed to provide the dedicated expertise, focus and investment needed to build and scale the Edge platform at the pace today's market demands. As a specialist tax technology leader, Fonoa will accelerate innovation with AI, expand engineering capability and respond swiftly to regulatory change while at the same time PwC will continue to deliver deep indirect tax expertise, global reach and tech-enabled managed services to help clients," said Peter Michalowski, Global Indirect Tax Network Leader at PwC. Fonoa plans to further develop Edge following the acquisition from PwC, integrating it with its modular tax infrastructure and AI layer. PwC will continue to deliver global indirect tax reporting and consulting services through Edge as part of Fonoa's AI-empowered, fully integrated tax operating system. With new capital and the acquisition of Edge, Fonoa plans to expand its platform to cover the full indirect tax lifecycle.
