Logan Roy said it best: “I love you, but you are not serious people.”

I have been thinking about that line a lot lately, because it captures something happening across enterprise software right now. The frontier labs have turned everyone into a builder. You can vibe-code a chatbot that estimates your VAT from a single receipt before your coffee gets cold. That is genuinely wonderful. It is also not what the world’s largest companies need.

Enterprise software remains stubbornly hard. Building an end-to-end system of record across every jurisdiction, with rules that change quarterly and regulators who can interrogate your audit trail years later, is a different kind of problem entirely. You cannot prompt-engineer your way through a cross-border tax obligation for Uber.

So while everyone deserves AI, some industries need AI built for serious people. Tax is one of those industries. And Fonoa is the team building it.

A quick framework. In a piece I wrote recently, I argued that the value of humans lives at the intersection of context and trust. The higher the requirement for either, the harder it is to automate. Tax sits squarely in the upper-right quadrant of that map: deep context (every jurisdiction is different, every client’s setup is unique, and the rules are a moving target) and high trust (get it wrong and you face penalties, audits, reputational damage). This is not a territory where a thin AI layer on top of a spreadsheet survives. It demands a purpose-built operating system with AI woven into every layer, and humans making the calls that matter.

That is exactly what Davor Tremac and his co-founders have spent years building. They saw this problem from inside Uber, one of the most operationally complex global businesses ever built, and they have been constructing the platform that companies at that scale actually need: tax determination across 190+ jurisdictions, tax ID validation in 100+ countries, e-invoicing for millions of sellers, and now returns and compliance reporting on the same platform.

Fonoa has just announced its $110 million Series C, led by Headline, with Eurazeo and Forestay joining as new investors. We at Dawn are reinvesting alongside our friends at Index, Coatue, and OMERS.

But the round is only half the story. The second announcement changes the game entirely.

Fonoa is acquiring Indirect Tax Edge from PwC. Edge powers indirect tax compliance for global enterprises: reporting, filing, analytics. Fonoa will integrate it with its own platform and AI layer, while PwC continues to deliver its tax consulting and services on top of it. Read that again. One of the Big Four chose Fonoa as the right team to build and scale its tax technology. A firm of that calibre does not make that call lightly.

Combined, Fonoa and Edge cover the full indirect tax lifecycle on a single data model. Determination, invoicing, returns, compliance. From start to finish, with AI agents monitoring obligations, populating returns, catching anomalies and assembling audit packs in seconds. The system does the work. Humans make the calls.

This is a huge moment, but it is still day zero.

Tax is one of the last great financial systems without a true system of record. The other functions of finance found their operating systems years ago. Tax has been waiting. The shift from fragmented point solutions to a unified, AI-native platform is only beginning, and with this round and this acquisition, Fonoa is positioned to lead it end-to-end.

We first invested in Fonoa’s Series B and have watched the team grow from a tax ID validation product into the most complete indirect tax platform for global enterprises. Uber, Netflix, Canva, Booking.com, Nebius. The customer list tells you everything about who trusts this team with their most complex compliance needs.

Serious people. Serious product. Day zero.

To Davor, Filip, and everyone at Fonoa: congratulations.
