With a natural talent for identifying value and building relationships, Max wanted to transform his casual interest in sports cards into a structured business. Starting with inventory from his sneaker business profits, Max and Matthew set out to establish a multi-platform presence across TikTok, eBay, and in-person card shows to build a sustainable business model.
