What started with hockey cards, Pokémon packs, and trips to the Toronto Expo turned into one of the fastest growing consignment businesses in Canada. In this episode of Passion to Profession, Karn breaks down the evolution of Slab Sharks and why the future of the hobby belongs to operators who think beyond cards on a table. We talk about: Building trust through customer experience Why storytelling matters in auctions and consignments The shift from “garage eBay sellers” to real infrastructure businesses How Canada’s hobby market is changing The role of technology, AI, and reinvestment in scaling a company Why emotional intelligence matters when handling collections This conversation goes far beyond buying and selling cards. It’s about building systems, earning trust, and understanding the emotional connection collectors have with their cards.
