Onetag

The company operates a vertically integrated programmatic advertising exchange combined with an AI-driven media curation layer. It creates value by improving the quality and efficiency of programmatic supply: placement-level data and a semantic knowledge graph are used to curate and filter impressions before they reach demand-side platforms, which can improve viewability, relevance and campaign performance, and reduce low-quality inventory. The exchange connects thousands of publishers with advertisers and programmatic buyers, providing scale and direct integrations, while the curation platform enables curated streams and bespoke deals for buyers and partners. Value creation for publishers comes from better monetisation of inventory; for buyers and data partners it comes from cleaner supply and more targeted activation, including immersive creative formats via the Aryel acquisition.
