Our team helps customers proactively prevent payment fraud. Commerce and financial transactions are increasingly moving online. While the internet has enabled easier and instantaneous payments, it has also introduced a layer of anonymity between the transacting parties. To fully leverage the power of online commerce: there must be mutual trust between parties. Without trust, commerce cannot happen. 

By providing a clear, accurate assessment of risk at multiple points of the end-user journey, we enable merchants to eliminate fraud losses, and create adaptive, frictionless experiences for low risk payments. We believe that machine learning is THE way to empower internet-scale businesses to prevent payment fraud.
