The Challenge

A payment processing startup handling $850M in monthly transaction volume was losing $4.2M monthly to sophisticated fraud rings that easily bypassed traditional rule-based systems. Alert fatigue had analysts reviewing 1,200+ false positives daily.

Our Solution

We deployed a graph neural network that maps transaction networks and identifies coordinated fraud patterns invisible to point-in-time models. Running on Apache Kafka with sub-50ms latency requirements, the system scores every transaction in real-time and uses adaptive feedback loops to evolve with new fraud patterns.
