Tom Vellios

Tom Vellios served as CEO of Zany Brainy alongside David Schlessinger, giving him deep operational experience in retailing to children and parents. His understanding of store-level execution, inventory management, and real estate selection was critical to Five Below's early store economics. Vellios was instrumental in designing the store layout and merchandising philosophy that made Five Below a destination rather than a convenience stop, emphasizing bright lighting, wide aisles, and high-energy displays that appealed to the tween demographic's preference for discovery and autonomy.

Tom Vellios is an American retail executive who co-founded Five Below in 2002 with David Schlessinger. Vellios brought operational expertise from his tenure as CEO of Zany Brainy, the educational toy-store chain that preceded Five Below. His role at Five Below focused on store operations, real estate strategy, and merchandising execution—the operational backbone that transformed Schlessinger's demographic insight into a scalable retail concept. Vellios was instrumental in developing the store prototype: approximately 9,000 square feet of high-energy, brightly lit selling space organized around eight merchandise worlds that encouraged browsing and discovery. He also shaped the real estate strategy of clustering stores within geographic markets to build brand awareness and operational efficiency, a approach that allowed Five Below to enter 44 states without scattering isolated locations. Vellios served as co-CEO and later in executive roles through the company's growth phase, contributing to the operational discipline that produced new-store payback periods of approximately one year. His emphasis on store-level execution and inventory turns provided the operational foundation for the company's post-IPO expansion.
