Retailers are looking to tech firms to reimagine their brick-and-mortar strategies as the importance of physical storefronts grows in the aftermath of the epidemic. Cooler Screens, which converts refrigerated doors into interactive advertising displays, had a fivefold increase in inbound leads at this year’s National Retail Federation conference and expects to clinch 10 transactions with significant national retail brands by 2023. These solutions are assisting firms in expanding their retail media operations. Cooler Screens and Placer.AI are two firms that assist stores with tracking foot traffic and dwell time, among other metrics. Cooler Screens converts freezer doors at retailers such as Walgreens and Kroger into digital displays with advertisements and graphics, and it has teamed with pharmacy giant Walgreens to expand its platform to 50 shops in the greater Chicago region. Placer.Ai charges businesses on a subscription basis and customises its subscription packages for each client.
