Cooler Screens

Cooler Screens, which has rebranded as CoolerX, is a Chicago-based in-store retail media company that operates a place-based digital out-of-home network built around smart screens embedded in retail environments. The company began by replacing the glass doors of refrigerated cooler aisles with digital screens equipped with sensors and IoT technology, turning cold cases into merchandising and advertising surfaces that display product information, pricing, promotions, and brand ads to shoppers at the moment of decision.

It has since expanded the surfaces its technology can support to include walls, end caps, windows, checkout lanes, and banner aisles, broadening its footprint within the store. CoolerX has installed thousands of screens across hundreds of retail locations in major United States markets, generating tens of millions of monthly views, and has worked with retail partners such as Walgreens, Kroger, Chevron, and GetGo convenience stores.

The company operates on an advertising-driven model in which retailers share in the revenue, and it emphasizes an identity-blind approach that does not collect personal information from shoppers, instead serving media based on sensors detecting physical proximity combined with external context such as weather, location, and time of day. By combining hardware, data, and an advertising sales operation, CoolerX functions as both a technology platform and a media owner, positioning its network as a way for brands to reach shoppers in physical stores at mass-media scale during the final steps of the purchase journey.
