Marketing speaker Jonah Berger is best known for Contagious: Why Things Catch On, which spent over six months on the New York Times bestseller list and has been translated into more than 35 languages. The book decoded the science behind viral content and word-of-mouth success, giving leaders a practical framework for making products, ideas, and behaviors spread. His follow-up works—Invisible Influence, The Catalyst, and Magic Words—continued to explore the hidden forces that shape decisions, the art of reducing resistance to change, and the power of language in persuasion.
His latest book, Magic Words: What to Say to Get Your Way, explores how subtle shifts in language can dramatically impact outcomes—from sales conversations to leadership communication. Berger’s research reveals that the right words, deployed strategically, can increase the likelihood of success in negotiations, marketing campaigns, and everyday interactions.
Berger has published dozens of articles in leading academic journals including Science, Journal of Consumer Research, and Management Science. His work bridges the gap between rigorous scholarship and practical application, translating complex behavioral science into tools executives can use immediately. He has consulted with Fortune 500 companies across industries, helping them understand consumer behavior, drive engagement, and accelerate adoption of new products and initiatives.
As a speaker, Jonah Berger combines cutting-edge research with compelling storytelling and real-world case studies.

Drawing from his groundbreaking research, Berger reveals the six principles that make products, ideas, and behaviors spread. This keynote unpacks real-world case studies—from viral videos to word-of-mouth successes—and delivers a practical framework leaders can apply immediately to amplify their message, increase engagement, and drive organic growth. Audiences leave with concrete strategies to make their content, campaigns, and initiatives more shareable.
Change is hard—not because people are stubborn, but because we push when we should pull. Berger explores the psychology of resistance and introduces five barriers that prevent adoption: Reactance, Endowment, Distance, Uncertainty, and Corroborating Evidence. By addressing these obstacles strategically, leaders can accelerate buy-in, whether launching a new product, driving organizational transformation, or influencing stakeholder decisions. This session is essential for executives navigating complex change initiatives.
The words we choose shape outcomes more than most leaders realize. In this keynote, Berger reveals how subtle shifts in language—whether in sales pitches, negotiations, or internal communications—can dramatically increase the likelihood of success. Backed by research and real-world examples, he demonstrates how to deploy language strategically to influence decisions, build trust, and drive action. Audiences gain a toolkit of linguistic techniques they can implement immediately.
Social influence operates beneath the surface, guiding decisions in ways we rarely acknowledge. Berger explores how peers, norms, and context shape consumer behavior and organizational dynamics. This session helps leaders understand when to harness social proof and when to differentiate, offering insights into positioning, branding, and strategic communication that drive competitive advantage.
