Case Study: Group M achieves better commerce media measurement and broader reach with Kard

Group M reaches 47M cardholders with Kard

The customer, Group M, a major media investment group, faced challenges with the fragmented and non-transparent nature of retail media "walled gardens." These single-retailer networks used incompatible measurement metrics and provided limited audience reach, making it difficult to allocate marketing budgets effectively and see a true picture of performance. To overcome these limitations, they turned to the independent commerce media network provided by Kard.

Kard's solution aggregated first-party transaction data from a vast network of retailers, banks, and fintechs, offering cross-retailer reach and neutral, closed-loop attribution. By using Kard's pay-for-performance model, Group M could tie ad spend directly to verified purchases. The vendor's network provided access to over 47 million cardholders, enabling hyper-personalized offers and a unified, transparent view of campaign incrementality and customer shopping patterns across hundreds of merchants.
