pubX

pubX operates as an AdTech software and transaction layer between advertiser demand and publisher supply. On the demand side, it helps agencies and advertisers automate campaign planning, audience construction, deal curation, and activation into external DSPs. On the supply side, it helps publishers connect inventory, surface first-party signals, and improve auction pricing and yield. The business creates value by increasing automation, exposing exclusive inventory, and improving monetisation outcomes across programmatic transactions.

pubX is a UK-based AdTech company focused on programmatic advertising workflow automation for both the buy side and sell side. Its product set includes a buying agent platform for advertisers and agencies, an AI-to-AI marketplace that matches advertiser demand with publisher inventory, publisher-facing bid intelligence for auction pricing and yield optimisation, and integration tools such as a bid adapter for header bidding environments.

The company generates value by improving media transaction efficiency and publisher monetisation within existing programmatic infrastructure rather than replacing DSPs or publisher stacks outright. Its customers are business users: advertisers, media agencies, publishers, and ad operations teams. Revenue appears to come from a mix of software access and transaction- or performance-linked fees tied to campaign activation, marketplace deal flow, and publisher revenue uplift.
