Joanna Drews

Joanna Drews serves as Chief Marketing Officer at Xandr, Microsoft's advertising technology division, where she leads strategic positioning and go-to-market efforts for one of the industry's most prominent programmatic advertising platforms. Her role places her at the center of a pivotal moment in AdTech, as Xandr navigates its integration into Microsoft's broader advertising ecosystem following the 2021 acquisition from AT&T. She is responsible for communicating Xandr's value proposition to agencies, brands, and publishers in an increasingly competitive landscape. Drews brings deep B2B marketing expertise to the complex AdTech sector, with a focus on enterprise-level programmatic solutions. Her work has been particularly significant in helping Xandr maintain brand identity and market relevance through a major ownership transition, a challenge that requires both strategic clarity and nuanced stakeholder communication across the buy and sell sides of digital advertising. Operating in a market defined by rapid technological change, privacy regulation shifts, and intensifying competition from Google, Amazon, and The Trade Desk, Drews has focused on articulating Xandr's differentiated position as a premium, data-driven programmatic platform backed by Microsoft's scale and first-party data assets.
