Deal Partner Information
Building on both these trusted publisher relationships and the tech stack that powers their revenue growth, pubX's market-leading solutions have culminated in a fully Agentic, end-to-end buying platform.
pubX is one of only a small number of companies globally to have run agentic advertising campaigns end-to-end, agent-to-agent.
We create custom Buyer agents and power the Sales agents for the major publishers you already love working with so their inventory and audiences are discoverable Agentically. Buyer and Sales agents negotiate directly, AI to AI, using publisher first-party data as a result of our five years of trusted publisher relationships. You submit a media brief in plain language and activate deals directly with thousands of premium publishers, matched only to the audiences and placements that fit your campaign goals. It behaves like a direct publisher buy, one to many, except you get every format the publisher's media kit offers instead of only what legacy programmatic pipes expose. Real time Agentic optimisation throughout the campaign is also built in. Amongst the efficiencies of Agentic, unlike the legacy programmatic infrastructure there is no need for costly 3rd parties in optimisation, reconciliation and campaign setup. Inventory is vetted and verified for quality, viewability and non-MFA. Removing the DSP and SSP layer enables materially more of the budget to be translated into working media automatically delivering better performance and outcomes for your brand. pubX is platform agnostic, built on open standards including AdCP, AAO and IAB.
