Topsort

Topsort is a leading retail media infrastructure company that empowers marketplaces, retailers, and brands to establish and scale their own advertising businesses. Founded in 2021, the company's mission is to democratize the sophisticated, auction-based advertising technology previously accessible only to tech giants. Topsort provides a suite of tools and APIs that enable clients to launch and manage sponsored listings, display ads, and other native advertising formats, thereby creating new, high-margin revenue streams. The platform is built on a foundation of privacy-first principles, operating without the use of third-party cookies and focusing on product information rather than user data for targeting. This approach, which they term 'Clean Ads,' ensures a more transparent and privacy-friendly advertising ecosystem for consumers, advertisers, and platform owners alike.

The company's core technology revolves around a powerful, AI-driven auction engine that optimizes ad placements in real-time to maximize relevance and return on ad spend (ROAS). Topsort's flexible, API-first infrastructure allows for seamless integration with existing e-commerce platforms and technology stacks, offering a customizable, white-label solution that maintains brand consistency for their clients. By providing tools for auto-bidding, budget pacing, and detailed analytics, Topsort equips its partners with the capabilities to compete with major players in the retail media landscape. With a global presence and hubs in key markets like Boston, Silicon Valley, São Paulo, and Santiago, Topsort supports a diverse range of customers across more than 40 countries, including prominent names like Poshmark, Cencosud, and Glovo. The company is backed by significant venture capital investment, fueling its expansion and continuous innovation in the rapidly growing retail media sector.
