About Whatnot

Whatnot is a community marketplace where you can safely buy, sell, go live and build a community with other like-minded people.

We got our start offering a buying and selling experience to collectors of Funko Pops and Pokemon cards. We became the leading marketplace for those communities and have found success launching into categories like sports cards, NFTs, and vintage fashion.

In July of 2022, we raised $260 million in a Series D funding round bringing our valuation to $3.7 billion, a 2.5x increase since our $1.5 billion valuation in September of 2021.

Our mission is to enable anyone to turn their passion into a business and bring people together through commerce. We enable anyone to connect, transact and build a business in one place -- Whatnot is bringing the in-person retail experience online.
