The document summarizes a presentation by Heap Analytics on how direct-to-consumer retail brands can use data to build relationships with consumers. It discusses how these brands employ tactics like simplification, curation, education and experimentation to personalize the customer experience. It also covers how they measure consumer behavior through conversion rate optimization, identifying moments of opportunity, acquisition channel analysis and A/B testing measurement to form a continuous customer feedback loop using data instead of personal interactions. The presentation provides examples from successful D2C brands like Allbirds, Thirdlove and Casper that employ these techniques.
