On today’s episode, Kara welcomes Doss Cunningham, Chairman and CEO of Nutrabolt, the powerhouse behind consumer-loved brands like C4 Energy, Cellucor, and XTEND. Over the last 20 years, Doss has led Nutrabolt to become the largest independently-owned active health and wellness portfolio in the world, trusted by athletes, fitness enthusiasts, and millions of consumers around the globe.
Doss shares the story of how Nutrabolt scaled from a single sports nutrition brand into a global performance wellness company. We dive into the rise of C4 as one of the fastest-growing energy drinks in the U.S., why Gen Z is reshaping the wellness space, and how athlete partnerships with stars like Saquon Barkley, CJ Stroud, and even investor Kevin Hart are fueling the brand’s cultural momentum. From building sustainably while staying private, to fostering a mission-driven culture, to creating a one-of-a-kind Austin HQ that reflects the company’s vision—this episode is packed with lessons for entrepreneurs, brand builders, and leaders chasing growth with purpose.
