Apr 30 – May 1, 2026 Meeting, Denver

Introducing our keynote speaker…

For the Culture: The Power Behind What We Buy, What We Do, And Who We Want To Be

Speaker: Marcus Collins, Ph.D., Professor in Residence at TikTok, Best-Selling Author, University of Michigan Professor, 2023 Thinkers50 Radar Award Winner, and Award-Winning Marketer

There is no external force more influential to human behavior than culture—full stop. This makes culture a cheat code for CEOs with a vested interest in getting people to adopt the behavior. Those who understand the dynamics of culture are more likely to have influence, while those who do not are almost always influenced by those who do. In this talk, Marcus pulls from both theory and practice—using learnings from his work spearheading digital strategy for Beyoncé to working with Fortune 500 companies like Apple, McDonald’s, and Google—to break down the ways in which culture influences behavior and unpacks how to leverage its power to get people to move. Professor in Residence at TikTok, Best-Selling Author, 2023 Thinkers50 Radar Award Winner, Award-Winning Marketer, Marshall Goldsmith 100 Coach, and University of Michigan Professor, Marcus is the recognized authority on leveraging the power of culture to influence behavior, inspire collective change, get people to share your vision, and most importantly, move them to take action.
