The Agentic Advertising Platform for Publishers and the Buy Side. Built on Trust.

pubX is one of only a small number of companies globally to have run agentic advertising campaigns end to end, agent to agent. Built on five years of trusted publisher relationships and AI infrastructure that prices more than 5 trillion auctions annually, pubX connects publishers, advertisers and agencies through autonomous buying and selling agents — delivering more efficient, higher-value programmatic outcomes for both sides.

Most companies arrived at agentic advertising from a slide deck. We arrived from five years on the publisher's side. That foundation is what separates us from the experimental — our technology is battle-tested, our data is real, and our results speak for themselves.

For publishers: first-party data becomes a competitive advantage, with sales agents negotiating the best value for every impression.

For advertisers and agencies: buying agents autonomously evaluate premium inventory, build high-performing segments, and activate campaigns - powered by data unavailable through traditional programmatic.

One platform. Two powerful solutions. Full transparency on both sides.
