Kevin Ryan

Kevin Ryan is one of the most consequential figures in the history of digital advertising and New York City's technology ecosystem. He is best known for his leadership at DoubleClick, where he served as President and COO before becoming CEO in 2000, helping to build the company into the defining ad-serving infrastructure of the early internet era. DoubleClick's technology established foundational standards for how digital ads were delivered, tracked, and measured — work that shaped the entire programmatic advertising industry that followed. Google's $3.1 billion acquisition of DoubleClick in 2008 cemented its legacy as one of AdTech's most pivotal companies. After DoubleClick, Ryan channeled his operational expertise and industry relationships into company building at scale. He founded AlleyCorp, a New York-based venture studio and investment firm dedicated to launching and growing technology companies, with a particular focus on the NYC ecosystem. Through AlleyCorp, Ryan co-founded or seeded a remarkable portfolio of breakout companies including Business Insider (digital media), Gilt Groupe (luxury e-commerce), and MongoDB (enterprise database technology), demonstrating a rare ability to identify and build category-defining businesses across multiple verticals. Ryan is widely regarded as a cornerstone of the New York tech community, having helped establish the city as a credible rival to Silicon Valley for startup formation and venture activity. His blend of deep AdTech operational experience and serial entrepreneurship makes him a unique figure — equally at home discussing ad-serving infrastructure and early-stage company building. He remains active through AlleyCorp, continuing to found and invest in new ventures.
