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 need automated decisions that run in real time across billions of signals.
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 bring the auction technology only a handful of Silicon Valley giants had to everyone else.
2022 Auctions
We launch our core auctions infrastructure and Campaign API, giving any commerce platform a real-time marketplace for placements.
2023 Series A
We raise our Series A and launch BIDLESS™ autobidding, so advertisers win without manual bidding.
2024 Formats
Sponsored Brands and Video Ads go live: four ad formats running on one commerce media infrastructure.
2025 Everywhere
We launch Toppie and Toptimize, and expand beyond onsite into offsite and in-store.
"Commerce platforms deserve the same infrastructure that powers the world's largest marketplaces."

/ 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.
