When I first wrote about Whatnot in February of last year, they were just getting started. Aiming to be the GOAT of collectible toys, they were focusing first on being the go-to trusted spot for buying and selling authenticated Funko Pop figurines. A few months later, as they expanded into categories like pins and Pokémon cards, the company started to build out a live shopping platform — think of something along the lines of a TV shopping network, but swap out the studios and camera crews for folks at home with iPhones selling to an audience of fellow collectors.
