Sean Downey

Sean Downey is President of Americas and Global Partners at Google, where he leads the company's advertising business across North and South America and works with marketers, agencies, and partners on how they buy and measure media. He moved into the role after running the Google Marketing Platform for the Americas, helping advertisers advance their digital marketing maturity through data and technology. Before joining Google in 2008, Downey was Vice President of Buy Side Sales at DoubleClick, where he led the agency and advertiser business, and he worked across a series of advertising-technology startups bringing rich media, programmatic buying, and analytics to market.

His talks focus on how AI is reshaping marketing, the rise of creator partnerships, and his argument that the future of brand is built on trust rather than reach alone. Downey is a fixture at major industry events, speaking at CES and hosting YouTube's Brandcast upfront in New York, where he makes Google and YouTube's case to media buyers. On stage he speaks as a platform operator about the economics of advertising, measurement, and where marketers should place their bets as buying becomes more automated.

He is based in New York.
