Tash Whitmey

Managing Director, Tesco Media & Insight Platform Tesco

With a track record of impressive achievements across three decades, Tash Whitmey is a media industry leader whose vision and stewardship turned Tesco Media into the ultimate media partner, transforming it from a retailer with data to a media owner with soul, scale and storytelling power.

Appointed in 2023 to create and lead a new media and insights organisation within Tesco, Tash’s vision to be the ultimate media partner for clients and agencies has been instrumental in Tesco Media’s success. In two years, Tash has turned it into a trusted and multi-award-winning retail media network that continues to set the pace for retailer-owned advertising today.

In 2025, under Tash’s leadership, Tesco Media was recognised across the industry with more than 23 award nominations and multiple major wins. Most notably, being named Media Brand of the Year at the Media Week Awards and Retail Media Network of the Year at Retail X, where Tash was also shortlisted for Retail Media Person of the Year.

Tash began her career at Tesco overseeing a major transformation of Clubcard, seeing Clubcard membership grow to more than 23m and app users to 16m. She subsequently spent almost two decades in senior leadership roles at Havas, including as UK CEO for Havas Helia, developing successful strategies for brands including Pets at Home, adidas, easyJet and Diageo. Returning to Tesco Group in 2023 perfectly married her external media and loyalty experience, with prior Tesco experience.

Tash is a Fellow and former non-exec director of the Marketing Society, featured in Data IQ’s 100 Most Influential People in Data and was included in Campaign magazine’s A-list for three successive years.
