Stackline

Stackline is a US-based private software company that sells enterprise commerce and retail media software to consumer brands, retailers and agencies. Its platform spans retail media campaign management, customer data, attribution, pricing intelligence, shopper research, landing pages, checkout, mobile apps and conversational commerce. The company generates revenue primarily from recurring software subscriptions, with commercial terms likely varying by module, retailer coverage, data volume and customer scale. The business is built around helping brands manage performance across retailer ecosystems such as Amazon, Walmart, Target and Instacart from a unified platform. Its value proposition is operational consolidation: centralising campaign execution, measurement, retail data activation, pricing visibility and direct commerce workflows that would otherwise sit across fragmented retailer tools and internal teams.
