Case Study: Košík.cz boosts campaign efficiency with Samba.ai

Košík.cz - Customer Case Study

Košík.cz, one of the best-known online supermarkets in the Czech Republic, wanted to make its marketing more efficient by using customer data more effectively across channels. The company needed to move beyond basic retargeting, better connect internal teams and processes, and shift from cookie-based targeting to real-user audiences with faster, more dynamic data distribution. Samba.ai helped address this challenge with its CDP and customer data activation capabilities.

Samba.ai implemented a central platform to unify customer data, create dynamic audiences based on purchase behavior and engagement, and automatically sync them into Sklik for real-time campaign optimization. The solution also powered automated scenarios such as re-engaging inactive users and upselling frequent buyers. As a result, Košík.cz shifted 50% of ad spend from retargeting to first-party customer lists, achieved a higher conversion rate through dynamic segmentation, and improved data match rates in Sklik by 20% compared with Meta and Google.
