Switzerland-based KA-EX has appointed Aaron Heidebreicht as CEO North America, a hire that signals the brand is shifting from market-entry mode to full commercial buildout across the United States. The appointment follows a national GNC rollout across 2,200 stores in August 2026 that pushed the brand past 4,000 US points of sale — a distribution footprint most European supplement imports take years to reach.
Heidebreicht brings more than 20 years of sports nutrition experience to the role. He previously served as Chief Commercial Officer at KAGED and most recently ran Applied Nutrition's North American business as CEO. His earlier tenure at GNC gives him category-specific retail relationships that most incoming executives would spend 12 to 18 months building from scratch. He operates from Nashville, Tennessee, and is tasked with assembling the brand's dedicated US commercial team.
Retail Velocity
The distribution calendar is aggressive. Vitamin Shoppe is set to add KA-EX across 700+ doors in January 2027, the same month Earthbar moves from test markets to a full-chain rollout. The brand is also listed as one of The Feed's highest-growth SKUs in 2026, suggesting premium endurance and fitness consumers are converting at meaningful rates. For buyers and category managers watching the functional beverage and sports nutrition shelf, this trajectory puts KA-EX in a short list of European-origin brands that have achieved scaled US specialty placement within a single fiscal year.
The product range is currently two SKUs — Creatine + Energy and Cortisol Stress Reducer — each available in ready-to-drink and ready-to-mix formats. The RTD format runs on VICAP, the brand's patented dual-chamber cap technology that keeps active ingredients separated from liquid until the moment of consumption. Both products carry Informed Sport and NSF certifications, which matter for the athletic and team-sport accounts KA-EX is cultivating, including Brooklyn FC and Tudor Pro Cycling.
What This Signals for Operators
For foodservice buyers, hotel fitness amenity programs, and specialty retail operators, KA-EX's expansion illustrates a broader pattern in the functional beverage category: European brands with differentiated ingredient-stability technology are finding faster US traction through specialty fitness retail than through traditional grocery or foodservice channels. Distribution at GNC, The Feed, GoPuff, and Rumble is a deliberate channel stack — each retailer addresses a distinct purchase occasion, from gym-adjacent impulse to online subscription.
Brands entering premium fitness retail at this velocity typically increase trade marketing spend as door counts scale. Operators sourcing functional RTDs for hotel gyms, stadium concessions, or premium food halls should expect more competition in this segment through 2027, with ingredient-differentiation claims — rather than flavor or price — driving the shelf conversation.
