About Alt
Alt is a marketplace for alternative assets, primarily focusing on trading cards from categories like sports (basketball, football, baseball, soccer) and Pokémon. The platform facilitates buying and selling through auctions and fixed-price listings, and provides services such as borrowing against collectibles, a secure vault for storage, and market trend analysis. Users can manage their collections and access the platform via mobile apps for iOS and Android. Launched in March 2021 with $31 million in funding, Alt secured an additional $75 million in a Series B round in November 2021, with backing from investors like Seven Seven Six, Vibe Capital, and athletes such as Tom Brady and Kevin Durant. The company aims to reinvent trading card collecting by offering services like 'Liquid Auctions' and providing financing to collectors to enhance liquidity.
Skills
About the Role
You'll build a predictable growth engine across both sides of the Alt marketplace, sellers and buyers. Instead of running one-off marketing tests, you'll turn today's experiments into real, instrumented, repeatable systems that move the north star metric of unique submissions. You'll partner closely with the founder and marketing lead, own the funnel end to end, and have the opportunity to grow into leading the growth function over time. You'll think like a PM, build like an engineer, and take on a high-ceiling seat with real ownership.
