The Build
Slow pivot, then vertical takeoff
Feedzai's trajectory has the arc of a rocket - flat for a long time, then sharply up. The early years were about finding product-market fit across domains that didn't quite fit. When the team landed on financial fraud, something clicked: their distributed, real-time machine learning stack was precisely what banks needed as card-not-present fraud exploded with the shift to digital commerce.
By 2021, Feedzai had raised $200 million in a Series D round led by KKR, crossed the unicorn threshold, and was processing payments for four of the five largest North American banks. Lloyds Banking Group, Citibank, and Capital One were using Feedzai's platform. The company had grown from a Portuguese research spin-off to a San Francisco-headquartered global operation with employees on four continents.
"Fraud isn't just numbers on a balance sheet. It's families losing their savings."
- Nuno Sebastiao
The October 2025 Series E - $75 million, valuation now $2 billion - came alongside the ECB announcement. The timing was deliberate: Feedzai was no longer just a fraud detection vendor. It had evolved into what Sebastiao calls a RiskOps platform, combining real-time transaction monitoring, anti-money laundering compliance, behavioral biometrics, and AI explainability tools into a unified system that financial institutions could deploy without stitching together a dozen point solutions.
The ECB partnership is arguably the most consequential contract in Feedzai's history. The digital euro - expected to launch between 2027 and 2029 - will be the first central bank digital currency for the eurozone. Feedzai, working with PwC, will provide the central fraud risk scoring layer that sits beneath every transaction. The stakes are not abstract: a failed fraud model at this scale would undermine trust in a sovereign digital currency before it has a chance to take root.
Sebastiao has spoken about fraud in terms that go beyond market opportunity. "My responsibility to my team," he has said, "is to aim for what seems like impossible goals and to ensure our people have all the resources they need to succeed as well as the tools to constantly innovate and challenge the status quo." That philosophy - combine ambition with infrastructure - is visible in everything from Feedzai's product architecture to his retention of the company's Portuguese roots when market logic suggested otherwise.
