Welcome to Nutrabolt

Doss Cunningham is the Chairman and Chief Executive Officer of Nutrabolt, the force behind powerhouse brands including C4®, Cellucor®, XTEND®, and its partner brand Bloom Nutrition. An Austin native, Cunningham has led the company’s growth from a startup into a global active health and wellness company with over $1 billion in annual sales.

Cunningham’s journey began in 2004 when he joined a sports nutrition startup as one of three co-founding partners. Initially serving as Chief Financial Officer, he applied his finance education to establish the company’s foundational accounting and operations. By 2008, he had transitioned into the role of Chief Executive Officer, driven by a vision to evolve Nutrabolt into a holistic performance-focused organization.

Under Cunningham’s leadership, Nutrabolt has expanded from its original supplement roots to a robust portfolio that includes powders, capsules, and ready-to-drink energy beverages. The flagship brand, Cellucor®, paved the way for the acquisition of XTEND®, and the creation of C4®, a category-defining brand in both pre-workout supplements and energy drinks.

In 2024, Nutrabolt unveiled its new 75,000-square-foot global headquarters in West Austin. The state-of-the-art facility features a cutting-edge fitness center and physiology lab that has hosted top-tier notables including Kevin Hart, Bijan Robinson, C.J. Stroud, Lance Armstrong, and so many more.

Cunningham continues to push the boundaries of innovation and strategic growth. In January 2024, he led a $90 million minority investment in Bloom Nutrition, a wellness brand founded by Mari Llewellyn and Greg LaVecchia, known for its popular greens and superfood products. The partnership aimed to expand Nutrabolt’s reach to a more female-forward audience. The collaboration launched with Bloom’s sparkling energy drink, which sold over 1 million cans in its first 30 days on the market.

From just five employees to a 500-person global workforce, Cunningham has led Nutrabolt through continuous year-over-year growth. His commitment to excellence, innovation, and community has firmly positioned Nutrabolt as a trailblazer in the active health and wellness space.
