n a world where consumers increasingly value self-expression and individuality, the market for hard-to-find fashion, collectibles, and electronics has never been hotter.

Our global platform offers unique access to current culture while our data-driven, bid-ask model provides buyers with the real-time visibility to know they’re getting a fair price.

With key leadership and an inspiring vision in place, we believe we’re poised for significant growth: into new product verticals, new audiences, and new geographies. To get there we’re looking for flexible, all-in teammates who are excited by ownership and the opportunity to take on emerging challenges.

If you’re a doer who’s ready to solve tough problems with plenty of laughs along the way, we’d love to hear from you. We welcome, embrace, and respect all dimensions of diversity. We’re committed to creating an inclusive environment where all team members are valued, supported, and respected—and no, you don’t need to know a thing about sneakers or fashion.
