SEON was born from necessity. Co-founders Tamas Kadar and Bence Jendruszak were building a cryptocurrency startup when relentless fraud attacks threatened its survival. Frustrated by slow, opaque anti-fraud tools that damaged user experience and blocked legitimate customers alongside bad actors, they built something different: an agile, transparent platform that stops fraud without compromising growth.
Today, SEON protects over 5,000 businesses globally and has prevented more than $300 billion in fraud losses. Powered by 900+ real-time data signals and an adaptable AI rules engine, SEON serves as the command center for risk and AML decision-making — helping businesses detect threats, automate compliance, and deliver seamless customer experiences across fintech, eCommerce, iGaming, and beyond.
With 350+ fraud experts operating across the Americas, EMEA, and Asia-Pacific, SEON combines deep engineering capability with frontline industry knowledge, enabling teams to move fast without sacrificing security.
