Whatnot is the largest livestream shopping platform in the US, UK, and Europe. Millions of people come to Whatnot every day to buy, sell, and connect over the things they love, from sneakers to sports cards, vintage fashion to fine jewelry, comics to Pokémon, beauty, electronics, and hundreds of other categories. In 2025, live sales on Whatnot surpassed $8B, more than doubling the year before. Over 20 million accounts were created last year alone, and we have been the #1 shopping app in both the US and UK. Weve built a real business, but were nowhere near done. Live commerce at this scale has never been done in the West, which means the people here now are shaping how an entirely new industry develops. The pace here is fast and the expectations are high. We move quickly, prioritize ruthlessly, and trust people to own their work end-to-end. In return, careers grow faster, impact is real, and your colleagues will raise your standards. Its an environment built for people who want to do the best work of their careers alongside others doing the same. Were a remote, co-located team with hubs in the US, UK, Ireland, Poland, and Germany, and were hiring across every function.
