pubX

Emerging specialist in ML-driven ad stack optimisation for independent digital publishers

pubX is a UK-based adtech company focused on helping digital publishers maximise their advertising revenue through intelligent ad stack optimisation. The platform uses machine learning and data science to analyse a publisher's existing setup and recommend or automatically implement the optimal configuration of header bidding partners, ad formats, and demand sources — without requiring publishers to switch away from their existing technology stack. The company's core product acts as an analytics and optimisation layer that sits above a publisher's ad stack, continuously monitoring performance signals and making data-driven adjustments to improve yield. pubX targets independent and mid-sized publishers who often lack the in-house data science resources to compete with larger media organisations, positioning itself as an accessible route to enterprise-grade revenue optimisation. pubX operates on a revenue-share or performance-based model, aligning its incentives directly with publisher outcomes. It competes in the publisher monetisation and yield management space alongside tools like Assertive Yield, Automatad, and Browsi, differentiating itself through its machine learning-driven approach and its focus on working with a publisher's existing stack rather than replacing it.
