Cardlytics, Inc. operates a commerce media platform that connects advertisers with consumers through digital banking channels and purchase-data-driven targeting. Its core Cardlytics platform runs inside financial institutions' online and mobile banking apps, where consumers see offers and earn rewards funded by advertisers. The company also operates the Bridg platform, which uses point-of-sale data, including product-level purchase data, to support analytics, loyalty marketing, and closed-loop measurement. Cardlytics' model is built around anonymized transaction data, allowing marketers to target customers based on actual spending behavior rather than probabilistic audience models. The company serves advertisers across categories such as everyday spend, specialty retail, restaurants, travel, and entertainment, and it has maintained platform operations in the U.S. and U.K.
