For advertisers & agencies
Agentic campaign execution. Built on publisher trust.
Buyer and seller agents, educated by pubX, trained by you and governed on both sides of every transaction, let brands, agencies and publishers plan, buy, sell and optimise media directly — with trust earned one campaign at a time.
The agentic advantage
Stop managing platforms. Brief an agent.
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
From brief to live buy, agents in the loop
- 01
Upload your brief
Log into the pubX buyer agent platform and set your campaign parameters: audience, objectives, KPIs, budget and brand-safety requirements.
- 02
Evaluation & segmentation
Buyer agents analyse your brief against publisher inventory, first-party data and pubX intelligence, then build custom segments optimised for your goals.
- 03
Agentic deal creation
Seller agents on the publisher side work with your buyer agent to create exclusive products and packages, using publisher trust and first-party data unavailable elsewhere.
- 04
One-click activation
Once terms are agreed, the deal goes live as a fully activated buy. No DSP hand-off, no per-partner integration — creative can be live within minutes.
Built different
Demand that reaches inventory others can’t
Publisher-backed intelligence
Our agents don’t just optimise bids — they access exclusive inventory and first-party data from trusted publisher partners who’ve worked with pubX for years.
End-to-end agentic solution
Buyer agents negotiate directly with seller agents using real-time data, creating deals that balance advertiser performance with publisher yield.
Transparent & autonomous
Full visibility into inventory sources, segment composition and deal terms. The agents handle the complexity; you keep control of where your spend goes.
Direct by design
pubX’s buyer agent deals directly with the publisher’s seller agent on the open Ad Context Protocol.
