Sneaker Data Company Campless Relocates from Philadelphia to Detroit, a website that provides data to sneaker collectors (better known as “sneakerheads”), announces it is relocating its headquarters from Philadelphia to One Campus Martius in downtown Detroit. The company, which operates like a Kelly Blue Book for the secondary sneaker market by collecting, analyzing and distributing data about the industry, is receiving a significant investment from Detroit Venture Partners and Dan Gilbert. Campless is also launching “Collections”, a portfolio-like feature where sneakerheads can track the value of their shoes over time, compare their collection with other users and view financial metrics previously reserved for traditional assets like stocks and mutual funds.
