Sam's Club continues scaling MAP into a Retail Experience Network

Sam’s Club is expanding its Member Access Platform into a full-funnel retail media network.

BENTONVILLE, Ark. — Sam’s Club is expanding its Member Access Platform (MAP) into a full-scale “Retail Experience Network,” emphasizing closed-loop measurement and data-driven targeting as retail media shifts toward performance accountability.

The platform connects in-club, digital, and offsite engagement using first-party membership data, enabling advertisers to link media exposure directly to sales. “Our role is to leverage more than 40 years of first-party deterministic membership data to create programs that deliver clear business outcomes for our advertisers while ensuring those experiences are engaging and valuable for our members,” said Harvey Ma, vice president and general manager of MAP.

New capabilities include expert-led product content, in-club review tools, and influencer integrations, all designed to drive conversions across the shopper journey. MAP is also expanding measurement beyond its ecosystem through Rest of Market analysis, providing visibility into cross-retailer impact and improving return on ad spend.

The initiative reflects broader industry momentum toward measurable retail media, as companies such as Walmart integrate data, media and commerce into unified growth platforms.
