About Us

Topsort is a global, remote-first SaaS company that democratizes the exclusive and powerful auction-based technology so marketplaces and retailers can monetize faster and stress-free. Our core offering is an auction-powered infrastructure and APIs that help marketplaces build native ads monetization, such as sponsored listings, dynamic banners, and faster.

We are a fast-growing team with a can-do attitude and growth mentality. Our culture is one of constantly pushing the limits, embracing feedback and ambiguity, and being excited by new challenges. You will be one of the first 80 employees, so it is important that you are ambitious, have leadership skills, can act hands-on, and are not afraid of new challenges.

We build in the open, collaborate frequently, and hold each other accountable.
