SEON, a fraud prevention and AML compliance platform, has closed an $80m Series C funding round to accelerate its global growth.
The round was led by Sixth Street Growth, with participation from existing backers IVP, Creandum and Firebolt. New investors including Hearst also joined. This latest raise takes SEON’s total funding to $187m.
The company operates as a command centre for fraud and compliance, offering a single API that powers rapid customer onboarding, scalable compliance processes and advanced fraud detection. Its solutions are used by thousands of businesses across the world, including Revolut, Plaid, Nubank, Afterpay, Spotify and Entain.
The fresh capital will support SEON’s product innovation and AI development, alongside a global hiring push. It will also help the firm expand deeper into regions such as APAC and Latin America, tailoring its platform to local regulatory needs and fraud trends.
SEON has reported significant growth, analysing tens of millions of daily customer interactions and achieving rapid adoption across North America and EMEA. Its clients have cut fraudulent account creation by up to 90%, boosted accuracy in blocking suspicious transactions by more than 80%, and reduced manual review time by 75%.
The company also plans to build stronger partnerships with financial institutions and cloud providers, embedding its solutions as part of critical digital infrastructure. As part of the funding, Sixth Street Growth managing director Michael Bauer will join SEON’s board of directors, while Claire Zhang will serve as board observer.
SEON co-founder and CEO Tamas Kadar said, “Our mission has always been clear, to enable companies to prevent fraud without impeding legitimate growth. This investment allows us to continue serving the critical market need for fraud prevention and AML solutions that can scale at the speed of modern digital commerce. With global fraud losses exceeding billions annually, we are tackling a fundamental challenge facing businesses worldwide.”
Sixth Street Growth managing director Michael Bauer said, “Fraud is growing at an unprecedented pace in the age of AI, and businesses need better defenses. SEON has built the command center for fraud prevention and AML compliance that empowers organizations to combat bad actors without impeding real customer transactions. Their proprietary data signals and end-to-end workflow platform provide the real-time insights needed to make smarter decisions with confidence. Tamas, Bence and the team have built an important and mission critical solution for the challenges that online businesses face today, and we’re excited to support their continued global expansion.”
IVP partner Karthik Ramakrishnan said, “SEON is the world’s fastest-growing fraud prevention company and has greatly exceeded growth targets while expanding their platform capabilities. What sets them apart is their obsession with customer outcomes; 90% reductions in fraudulent registrations and over an 80% increase in preventing fraudulent transactions aren’t just metrics, they’re transformational business results.”
Creandum general partner Simon Schmincke said, “As an early SEON backer, we continue to be impressed by their execution velocity and market leadership. The team has built something rare, a platform that makes fraud prevention faster and more effective, not slower. Watching SEON scale from a promising startup to global market leader has been remarkable. We’re very excited to continue our support through their next phase of growth.”
