David Selinger

David Selinger founded RichRelevance in 2006 to give retailers the most advanced personalization platform for transforming customer data into extraordinary consumer experiences.

RichRelevance is ranked #1 for personalization in both the Internet Retailer 500 and Internet Retailer EU 250, and currently drives over one billion real-time decisions every day. David has led the company through four acquisitions and introduced multiple product lines to create new business value from data through personalization. Both RichRelevance and David (known as Selly to his friends and colleagues) are known for their innovation in this space—delighting consumers, generating revenue and profit for retailers, and creating an award-winning company; RichRelevance has been recognized by numerous publications as a top place to work by employee surveys.

An early pioneer in data analytics and personalization, David previously led the research and development arm of Amazon’s Data Mining and Personalization team. In that role, David developed and deployed three new recommender systems that increased Amazon’s annual profit by over $50 million (25% of US profit, 2003), setting the industry standard for recommendation services.

David also cofounded Redfin, a venture backed, industry-leading real estate search/brokerage company, where he helped to build the world’s first real-time mapping and real estate data analytics engine.

Recognized as a “40-under-40” innovator in the San Francisco region and amongst direct marketers, David holds a broad collection of patents in customer segmentation, analytics and data mining, including over a dozen pioneered at RichRelevance. He received his BS in Computer Science from Stanford University, and is active in social change, serving on the board of directors of Potential Energy, and as an advisor to the Family Giving Tree, Fostering Change for Children and Solace International.
