J.P. Flaum

Chief Executive Officer & Founder,

J.P. is CEO and Founder, guiding the strategic direction of the firm and contributing to the global conversation on talent and leadership. He has coached more than 120 executives (half of them CEOs) across every major industry and continues to partner with selected clientele facing critical leadership and human capital challenges.  He is a sought after speaker on the topics of talent, team building, and human potential and regularly addresses both private equity and CEO audiences.  He is also a guest lecturer on ‘Hiring Top Talent’ at the Stanford Graduate School of Business.

Known for his unusual ability to take leaders to new levels of performance, J.P. is an influencer and go-to voice on leadership and executive team effectiveness. He has coached CEOs and boards on issues related to leadership effectiveness, organizational design, succession planning, on-boarding, M&A integration, and conflict intervention. His clients have included Bain Capital, Berkshire Partners, The Carlyle Group, General Atlantic, Madison Dearborn Partners, and more. J.P.’s work and insights have been featured in the Harvard Business Review, Washington Post, New York Times and numerous other publications.

“Most CEOs have never truly learned how to assess talent, ask the most powerful leadership questions and proactively shape their own identity. In fact, they often don’t realize that asking for help is one of the most powerful things a leader can do. As executive coaches, it’s a thrill to help supercharge the best and brightest leaders in the world.”
