Commerce infrastructure for the next generation of marketplaces.
Topsort powers the auctions, ranking systems, and monetization infrastructure behind modern commerce platforms.
Three convictions that guide everything we build.
Commerce should run on auctions
Marketplaces and retailers need dynamic ranking and pricing systems — not static placements and manual sales.
Infrastructure should be accessible
The most powerful monetization systems shouldn’t only exist at companies like Amazon. Every commerce platform deserves them.
AI will run commerce operations
Modern marketplaces require automated decision systems that optimize in real-time across billions of signals.
Trusted by global retailers and marketplaces
Our story
At Topsort, everything we build is designed to unlock growth across the ecommerce ecosystem. We started in a world where advanced auction and AI-driven monetization technology was limited to a handful of Silicon Valley giants. That wasn’t good enough. So we set out to make world-class monetization accessible to everyone.
Built by engineers and operators from global technology companies.
