As the founder and CEO of Truman Company, Mark created a new model for strategy development and executive engagement based on co-creation and peer exchange. Working with market leaders including IBM, Avaya, The Economist, Manpower, and Gerson Lehrman Group, Mark’s team reinvented advisory boards, conferences, and online communities as vehicles for customer advocacy, organizational alignment, and transformative change.  

In 2006, Mark led the merger of Truman Company with Fifty Lessons, a pioneer in the use of storytelling and digital video for leadership development and executive education. The new company demonstrated the power of combining digital media, online community, and in-person events.
