Sarah Fay

Sarah Fay is one of advertising's most prominent insiders-turned-reformers, leveraging three decades of senior leadership at the world's largest media agencies to become a leading critic of surveillance capitalism and a vocal advocate for consumer privacy rights. As former CEO of Carat Americas, she oversaw one of the most powerful media buying operations in the world, giving her firsthand insight into the data practices and structural imbalances she now campaigns to change. Her decision to file an antitrust complaint against Google marked a significant moment — a credentialed industry veteran using her platform to challenge the dominant power structures of digital advertising. Fay's career trajectory spans the full arc of modern advertising's transformation. She held senior leadership roles at Aegis Media and Publicis Groupe before leading Carat Americas as CEO, where she managed billions in media spend and navigated the industry's shift to digital and programmatic. After departing the agency world, she founded Glasswing Ventures, focusing on AI, AdTech, and transformative technologies — positioning herself at the intersection of investment and advocacy for more ethical technology development. Today, Fay is recognized as a thought leader on AI ethics, data privacy, and the need for regulatory oversight of big tech platforms. She writes, speaks, and advises extensively on the future of advertising and consumer rights, arguing that the industry's dependence on behavioral surveillance is both ethically untenable and economically fragile. Her rare combination of operational credibility and reform-minded advocacy makes her one of the most distinctive voices in contemporary AdTech discourse.
