Investment thesis

FitLab positions itself as a builder and operator of sport-lifestyle brands rather than a passive investor, focusing on the convergence of athletic performance, culture, and style. It leverages in-house expertise and proprietary technology to develop and enhance fitness products, boutique fitness studios, competitive events and races, and AI-driven testing and tracking platforms. Its holdings span fitness equipment and apparel makers, group training studios, endurance race series, and performance training systems, reflecting a vertically integrated approach to shaping how people engage with sport and fitness.
