What does it take to start one of the fastest-growing consumer marketplaces? According to repeat founder Grant LaFontaine, it starts with an open mind. When he and his co-founder Logan Head launched Whatnot in 2019, they went into it know that their starting place and ending place would be completely different. The team opted to be customer-centric instead of vision-driven. Today, Whatnot is a live shopping marketplace that enables anyone to turn their passion into a business. Whatnot is like Twitch-meets-eBay and was most recently valued at $3.7B. Grant shares why they started building with a niche community (Funko Pop collectors), why creativity is vital for consumer startups, and why this generation of shoppers cares about authenticity.
