/What we believe

Three convictions that guide everything we build.

01

Commerce should run on auctions

Marketplaces and retailers need dynamic ranking and pricing systems, not static placements and manual sales.

02

Infrastructure should be accessible

The most powerful monetization systems shouldn't only exist at companies like Amazon. Every commerce platform deserves them.

03

AI will run commerce operations

Modern marketplaces require automated decision systems that optimize in real-time across billions of signals.

/Our story

Founded in Silicon Valley. Built for everyone.

The largest marketplaces built powerful internal auction systems that smaller retailers could not access. Topsort was created to bring that infrastructure to every commerce platform.

2021 Founded

Topsort starts in Palo Alto to democratize advanced ad monetization technology: the auction systems only a handful of Silicon Valley giants had.

/ Careers · We're hiring

Build the infrastructure behind modern commerce.

Commerce platforms used to rely on simple search results and manual merchandising. Today they rely on auctions, ranking systems, and machine learning.

The largest marketplaces built these systems internally. Most companies still don't have access to them.

Join us to change that.
