Our take
Live shopping is changing the way people engage with eCommerce and Whatnot is one of the key platforms driving this shift. The company operates across the US, UK, and Europe, where millions of people connect each day to buy, sell, and build communities around shared interests.
Founded in 2019, Whatnot allows real-time auctions where buyers can watch sellers showcase products and share their expertise, creating a more interactive and personal shopper experience. Sellers include individual creators and small businesses who use live shows to reach audiences and grow their online presence.
As of 2025, the company reports over $6B in sales, with sellers earning significantly more on average than other major marketplaces. And with a range of investor support, Whatnot is committed to developing new ways to make online shopping more social and community-driven.
