Fraud is the fight hiding in plain sight. Companies don’t talk about it until it breaks their ribs and empties their wallet. For Tamas Kadar and Bence Jendruszak, that beating came while running a crypto startup. Every attack felt like shadowboxing with opponents carrying crowbars. Instead of walking away, they decided to see the problem head-on. In 2017, they launched SEON, a platform built to hunt fraud and handle AML compliance in real time. Today it processes more than 15M daily transactions for over 5,000 businesses across the globe. That’s not a pivot, that’s a reinvention.
Now comes another milestone. SEON has locked in $80M in Series C funding led by Sixth Street Growth, joined by Hearst, Creandum, Firebolt, and IVP. Add that to a $94 million Series B led by IVP in 2022, a €10 million Series A led by Creandum in 2021, and the early rounds that gave them their first spark, and the tally hits $187 million. Investors aren’t just funding another fintech, they’re doubling down on a system that makes fraud sweat.
The platform is no buzzword machine. SEON operates as a single API command center, pulling from more than 900 real-time data signals. It fingerprints devices, checks IPs, verifies emails, scores behavior, screens transactions against global sanctions, and integrates with major gateways. The AI is explainable, the false positives are low, the architecture is cloud-native across AWS and Azure. This is not fraud prevention in theory, it’s the daily grind at scale.
The results speak. Revenue has grown 300% year-over-year. More than $300 billion in fraud losses have been prevented. Clients like Revolut, Nubank, Afterpay, Plaid, Spotify, and Entain are locked in. Offices in Austin, Budapest, London, and Jakarta give SEON reach across North America, Europe, and Asia-Pacific. Recognition has followed, including three straight years on CNBC’s World’s Top Fintech list, plus ISO27001 and SOC2 Type II certifications.
This new capital is not a victory lap, it’s acceleration. Headcount will scale from 300 to 500+ by mid-2026, with investment aimed at AI-driven product development, crypto-AML modules, advanced behavioral modeling, and dark-web intelligence expansion. North America adoption is the immediate target, with Latin America and Asia-Pacific lined up for deeper penetration.
Credit where it belongs. Co-founder and CEO Tamas Kadar and Co-founder and CTO Bence Jendruszak took a founder’s nightmare and turned it into a global safeguard. Respect to Sixth Street Growth, Hearst, Creandum, Firebolt, and IVP for backing a company that doesn’t just watch for fraud, it sees it coming.
