Ravelin

Ravelin is an AI-native enterprise fraud prevention and payments platform purpose-built for online merchants and payment service providers. Founded in 2015 and headquartered in London, Ravelin uses machine learning, graph network analysis, and behavioral signals to distinguish legitimate customers from fraudsters in real time, helping 300+ global brands reduce chargebacks, block account takeover, combat refund and promo abuse, and optimize 3D Secure authentication acceptance rates. The platform covers the full spectrum of digital commerce fraud and is backed by a dedicated fraud operations support team. Ravelin was acquired by Worldpay in February 2025 to enhance Worldpay's e-commerce security capabilities.
