Adsyield

Adsyield operates as an intermediary in the digital advertising value chain. It aggregates publisher inventory, connects that supply to direct and programmatic demand sources, runs auction logic intended to maximise yield, and shares resulting advertising revenue with publishers. Value is created by improving inventory utilisation, increasing fill rates and CPMs, and simplifying technical access to multiple demand sources for publishers.

Adsyield is a UK-based adtech company operating a monetisation-focused advertising network for digital publishers. Its platform connects publisher inventory with advertiser, agency and DSP demand, and positions itself around blending direct and programmatic demand within a single auction to improve fill rates, CPMs and publisher revenue. The company supports inventory across web, mobile app and CTV environments, with technical integrations through standards such as VAST, OpenRTB and Prebid.js.

The business appears to make money primarily by taking a share of advertising revenue generated through its network. Its direct customers are publishers and app developers seeking monetisation, while demand-side customers include advertisers, agencies and media buyers seeking access to inventory. Functionally, it sits between publishers and buyers as both a monetisation partner and demand aggregation layer rather than a pure self-serve software vendor.
