About
A leading retail media network enablement platform backed by Publicis Groupe, leveraging Epsilon's proprietary identity and data assets to help retailers compete in the fast-growing retail media space.
Epsilon Retail Media is a scalable, auction-based advertising platform built for e-commerce retailers, giving them full control over how, when, where, and how often ads are shown on their properties. The platform applies CORE AI artificial intelligence and CORE ID person-first identity within the ad server, supporting audience identification both within retail media environments and off-site. Using first-party sales data sourced directly from the retailer, it delivers targeted, personalized ad content to the retailer's e-commerce server, and once advertising placements are defined on a retailer's website, they become available for advertisers to bid on. To meet marketer needs, the platform applies AI-powered identity resolution to connect brands with shoppers and utilizes omnichannel attribution to tie performance to consumers without cookies or proxies. On the measurement front, Epsilon Retail Media advocates for moving beyond return on ad spend metrics toward measures that more genuinely reflect a brand's market influence and sales lift.
