Visit dunnhumby Alternatives

dunnhumby specializes in turning a retailer's own loyalty-card and transaction data into customer-level insight, historically best known for building Tesco's Clubcard loyalty program and its underlying analytics. Its products, marketed under names such as Compass and Uplift, help retailers and their CPG suppliers set prices, plan promotions, personalize offers and optimize assortment based on modeled customer response rather than aggregate sales trends alone. It works directly with individual retailers' first-party data, which differentiates it from syndicated data providers like Circana or NielsenIQ that aggregate data across many retailers into market-level views. Customers are grocery and general-merchandise retailers and the CPG brands that sell through them, typically on multi-year analytics and consulting engagements.
