SEON

SEON was founded in January 2017 by Tamas Kadar and Bence Jendruszak after the pair encountered relentless fraud attacks while building a cryptocurrency startup and found existing anti-fraud tools too slow and complex. The platform combines over 900 real-time first-party data signals with an adaptive AI rules engine to deliver fraud prevention, AML compliance, KYC, and transaction monitoring in a unified command center. Serving more than 5,000 businesses globally and claiming to have prevented over $300 billion in fraud losses, SEON operates from offices in London, Budapest, Austin, and Singapore with a team of 300+ employees. The company raised an $80 million Series C led by Sixth Street in September 2025.
