Surfside

Surfside is the operating system for the Retail Majority. The company is building the infrastructure that connects commerce, media, and measurement across the fragmented retail landscape. Surfside aggregates independent retailers and regional chains into a unified platform that enables advertisers to reach verified shoppers, activate media across channels, and measure performance against real economic outcomes, including sales, incrementality, and lifetime value.By unifying online and in-store purchase signals, Surfside converts fragmented retail activity into an enterprise-grade performance channel. Advertisers gain clarity, scale, and accountability beyond traditional media metrics, while retailers unlock new revenue streams and intelligence from the transactions they already process. Surfside sits at the intersection of advertising technology and retail infrastructure, transforming where and how performance media is planned, executed, and measured.
