Agentic Campaign Execution. Built on Publisher Trust.
pubX builds agent-to-agent infrastructure for advertising. Its buyer and seller agents, educated by pubX, trained by the client, and governed on both sides of every transaction, let brands, agencies and publishers plan, buy, sell and optimize media directly, with trust earned one campaign at a time.
The Agentic Advantage
Traditional programmatic buying leaves agencies managing endless platforms, fragmented data, and opaque inventory sources.
pubX changes this. Our buyer agents work on your behalf, analysing your campaign brief, accessing exclusive publisher inventory through trusted agent-to-agent negotiations, and creating custom segments that deliver performance at scale. You set the level of autonomy and approve at key steps; as trust is earned, autonomy grows.
The result: Campaigns that launch faster, perform better, and operate with full transparency.
How it Works
1) Upload Your Brief
Log into the pubX buyer agent platform and provide your campaign parameters: audience, objectives, KPIs, budget, and brand safety requirements.
2) Evaluation & Segmentation
Our buyer agents analyze your brief against our massive corpus of publisher inventory, first-party data, and proprietary pubX intelligence built on years of pricing and selling publisher inventory. The agents create custom segments optimized for your specific campaign goals. You set the level of autonomy and approve at key steps; as trust is earned, autonomy grows.
3) Agentic Deal Creation
Our sales agents (operating on the publisher side) work with our buyer agents to create exclusive programmatic products and packages that match your criteria, leveraging publisher trust and first-party data unavailable elsewhere.
4) One-Click Activation
Once terms are agreed, your deal goes live directly as a fully activated buy, executed through pubX’s agentic infrastructure. No DSP hand-off, no per-partner integration — creative can be live within minutes.
