Tamara Gruzbarg

Tamara Gruzbarg is one of AdTech's foremost experts on data clean rooms and privacy-preserving data collaboration, a domain that has become central to the industry's post-cookie identity strategy. As Chief Insights Officer at Habu — a data collaboration platform acquired by LiveRamp — she helps brands, publishers, and data partners unlock the value of first-party data without compromising consumer privacy. Her ability to translate complex data infrastructure into actionable business strategy has made her a sought-after voice as the industry grapples with signal loss and evolving privacy regulations. Gruzbarg's career reflects a consistent focus on extracting strategic value from data across retail, financial services, and AdTech. At Gilt Groupe, the luxury flash-sale pioneer, she led data and analytics efforts that helped the company build a sophisticated understanding of its high-value customer base — experience that gave her deep fluency in retail media and audience segmentation. She subsequently held senior data roles at Dun & Bradstreet, where she worked at the intersection of B2B data assets and marketing applications, broadening her expertise across identity and data enrichment. Her move into the clean room space with Habu positioned her at the leading edge of the cookieless transition, where she has become an active educator and advocate for privacy-safe data practices. She frequently speaks at major industry conferences and contributes to thought leadership around data collaboration frameworks, making her both an operator and an evangelist for responsible data use in modern advertising.
