At Kumanu, purpose drives everything we do. Now, we're bringing purpose to life through a series of inspiring conversations with the launch of PurposeCast with Dr. Vic Strecher, a weekly podcast that explores how purpose shapes what matters most in our work, our communities, and our lives.
Hosted by Vic Strecher, PhD—author, professor, and Kumanu founder—PurposeCast features in-depth conversations with thought leaders and changemakers who share the latest science and personal stories about purpose in their work, life and communities.

Each week, new episodes will explore timely questions around meaning, motivation, and what it takes to lead and live with purpose in today’s environment.
We invite you to follow, listen, and share PurposeCast with your networks. If you’re thinking about how to deepen purpose in your organization—or your own leadership—you’ll find ideas worth bringing to the table.
