Costco has added Moloco Commerce Media, a retail adtech firm, to its Costco Velocity retail media network, launching a new onsite ad format called Reserved Display that uses Moloco’s AI engine trained on Costco’s first-party data to serve personalized ads to shoppers on its ecommerce site. The partnership will begin with a beta program in Q2, with plans to expand ad slots, formats, and programmatic buying capabilities through SSP and DSP platforms in Q2 and Q3. The deal follows a recent partnership with Symbiosys to promote Costco products in Google Shopping results, as the retailer builds out the infrastructure behind Costco Velocity, its revamped retail media network.
