House of Athlete has an ambitious three-pronged business model—comprised of fitness and training facilities, supplements and apparel—that focuses on holistic wellness, from the physical to the mental. Six-time Pro Bowler Brandon Marshall has been a team player for his entire NFL career—but now he’s crafting his own roster, and funding the business they’re building with a personal $10 million investment. The team he’s assembled has helped him launch House of Athlete, a modern gym concept for professional and everyday athletes alike.
