Topsort builds AI-powered advertising infrastructure for commerce platforms. Founded in 2021, the company enables marketplaces, retailers, delivery apps, travel platforms, and commerce networks to launch and operate retail media businesses independently, without relying on legacy advertising platforms designed for publishers.
The core product is an auction-based ad serving system that processes commerce signals - catalogue data, search intent, inventory levels, budgets, and shopper relevance - in real time. The system handles thousands of queries per second with sub-5 millisecond latency, powering sponsored listings, display ads, offsite campaigns, and in-store media. This infrastructure allows commerce companies to monetise their traffic while maintaining control over their advertising operations.
Topsort serves customers across 40 countries and nine global regions. The company's technical focus spans low-latency systems engineering, real-time commerce signal processing, and commerce-specific ad technology - domains distinct from traditional publisher-focused ad platforms. The approach reflects a belief that advertising technology built for commerce use cases, rather than adapted from publishing, better serves the needs of modern commerce businesses.
