pubX
AI buyer and seller agents that let publishers, advertisers and agencies transact ad inventory directly.
pubX started out pricing and selling inventory for publishers and now builds buyer and seller AI agents that deal directly with each other on the AdCP standard. In October 2026 it bought media-quality firm Compliant and, at that month's Advertising Week in New York, ran a live purchase between agents for a Reckitt brand.
