Topsort

The company operates as an enterprise adtech infrastructure provider focused on retail media. It creates value by enabling retailers, marketplaces, delivery apps and similar commerce platforms to run their own monetisation of shopper attention through sponsored listings and other ad formats. Its API-first platform, ad server and bidding models become the underlying technology stack for these clients to launch and manage retail media networks across channels and markets.

Revenue is primarily generated through software and infrastructure contracts with these business customers, who pay for access to the platform, ad serving and campaign management capabilities, and for integration and configuration support. By also operating an integrated demand-side retail media network, it adds value by supplying aggregated advertiser demand into retailer inventories and simplifying campaign execution for brands, which likely produces additional revenue via media-spend or revenue-share arrangements.
