Adam Bain

Adam Bain is one of the most influential operators in the history of social media advertising, best known for building Twitter's global revenue business from near zero to over $2.5 billion annually. As President of Global Revenue and then Chief Operating Officer at Twitter, Bain architected the company's advertising products, sales organization, and monetization strategy, establishing Twitter as a major force in digital and mobile advertising. His work helped define how brands engage audiences in real-time social contexts, making him a foundational figure in the evolution of social AdTech. Bain joined Twitter in 2010 after serving as President of Fox Audience Network, News Corp's digital advertising network, where he gained deep expertise in programmatic and performance advertising at scale. At Twitter, he built out the MoPub mobile ad exchange (acquired by Twitter in 2013), expanded internationally, and championed native advertising formats that became industry standards. He served as COO from 2016 until his departure in late 2016, having helped stabilize and grow the business through a period of intense competition and public scrutiny. Today, Bain is co-founder of 01 Advisors, a venture and advisory firm that partners with high-growth technology companies to help them scale operations, revenue, and culture. Drawing on his operator experience, he works closely with founders navigating the challenges of building and monetizing technology platforms. He remains a respected voice in AdTech and venture circles, frequently sought out for his perspective on platform monetization, go-to-market strategy, and the future of digital advertising.
