Roxana Shekarabi

Roxana Shekarabi is a retail media specialist at GroupM Nexus, where she leads strategy and activation efforts for one of the world's largest media investment groups as retail media has emerged as one of the fastest-growing channels in digital advertising. She works directly with major brand clients to help them allocate, activate, and measure spend across a fragmented landscape of retail media networks including Amazon Advertising, Walmart Connect, Kroger Precision Marketing, and a growing number of emerging networks from retailers seeking to monetize their first-party data and digital shelf space. Her work is particularly focused on the measurement challenges that have come to define retail media's maturation as a channel — specifically incrementality testing and standardization of attribution methodologies across networks that each operate with proprietary metrics and reporting frameworks. This positions her at the intersection of client advisory, media investment, and the broader industry push toward more consistent retail media measurement standards. Given the bio provided, Shekarabi operates within GroupM Nexus, the performance and technology arm of GroupM, which serves as the activation engine for WPP's media agencies including Mindshare, Wavemaker, and EssenceMediacom. Her role reflects the significant organizational investment major holding companies have made in building dedicated retail media practices as brand budgets shift toward closed-loop, commerce-adjacent environments.
