pubX

pubX is a agentic programmatic advertising platform for buyers and publishers.

Analyst Perspective

pubX is a UK-based AdTech company focused on programmatic advertising workflow automation for both the buy side and sell side. Its product set includes a buying agent platform for advertisers and agencies, an AI-to-AI marketplace that matches advertiser demand with publisher inventory, publisher-facing bid intelligence for auction pricing and yield optimisation, and integration tools such as a bid adapter for header bidding environments. The company generates value by improving media transaction efficiency and publisher monetisation within existing programmatic infrastructure rather than replacing DSPs or publisher stacks outright. Its customers are business users: advertisers, media agencies, publishers, and ad operations teams. Revenue appears to come from a mix of software access and transaction- or performance-linked fees tied to campaign activation, marketplace deal flow, and publisher revenue uplift.

Category Differentiation

pubX is an AdTech platform for programmatic media buying and publisher monetisation, not a publisher itself. It should not be confused with larger incumbent infrastructure vendors such as PubMatic, although they compete in adjacent programmatic categories.

pubX: About

pubX operates as an AdTech software and transaction layer between advertiser demand and publisher supply. On the demand side, it helps agencies and advertisers automate campaign planning, audience construction, deal curation, and activation into external DSPs. On the supply side, it helps publishers connect inventory, surface first-party signals, and improve auction pricing and yield. The business creates value by increasing automation, exposing exclusive inventory, and improving monetisation outcomes across programmatic transactions.

How pubX Works & Monetises

Business model analysis and core revenue streams

pubX appears to monetise through a blended model combining software access with transaction- and outcome-linked fees. The buying platform likely supports SaaS or platform access pricing for advertisers and agencies, while the marketplace likely earns a take-rate or platform fee on negotiated programmatic deals. Publisher-facing optimisation products appear suited to value-based commercial models tied to revenue uplift, improved CPMs, fill rates, or usage of monetisation tooling.

Revving's Transactional Funding: Interview with CEO Chris Pettit

Quo Vadis published an interview with Chris Pettit, CEO and co‑founder of Revving, describing Revving’s Transactional‑Based Funding model which uses verified transaction data to advance earned revenue and reduce cash‑flow delays in the advertising supply chain. Pettit argues payment timing constrains choices for smaller and scaling AdTech businesses and that advancing earned revenue democratizes funding versus traditional invoice-based finance. The piece links the funding approach to emerging agentic advertising workflows and says Revving is "MCP‑ready" for agentic buyer‑seller systems, suggesting funding could become integrated into real‑time commercial workflows. The post also lists several Cannes Lions events (including an off‑the‑record lunch with Michael Rubenstein of Firsthand AI on June 25) and was published on 2026-06-18.

Publicis Reframes Identity with LiveRamp Acquisition

Quo Vadis published an analysis and hosted an interview with Mathieu Roche to unpack Publicis’s acquisition of LiveRamp and its implications for identity economics in advertising. The piece argues Publicis bought positional infrastructure and data-exchange capability rather than short-term profits, following prior buys such as Epsilon and Lotame. It frames identity as a means of exchange (a currency that enables trades of inventory, audience data and measurement) and revisits the 'Identity Trade-Off Frontier'—the historical tension between scale and ID precision—arguing recent infrastructure advances have expanded that frontier. The article introduces the 'Gravity Theory of Data Trade' to explain network effects and raises neutrality and lock-in questions now that LiveRamp sits inside a major holding company. The post also lists related Cannes events and calls out wider industry shifts from cookies toward infrastructure and collaboration.

Audion CEO on Performance Audio, AI, and Measurement

Quo Vadis published an interview with Arthur Larrey, CEO and co‑founder of Audion, on June 9, 2026. Larrey discusses the evolution of digital audio from an awareness channel into a performance channel driven by better data, activation technologies, cross‑channel measurement, and AI. Audion positions itself as a performance audio platform that emphasizes proving incremental business outcomes across awareness, consideration, intent, site visits, lead generation and sales. The interview highlights dynamic creative, contextual targeting, AI‑assisted campaign optimization, and the convergence of audio and video (notably video podcasts). The post also lists multiple Cannes Lions events and panels where industry leaders (e.g., Sir Martin Sorrell, Brian O’Kelley, Brian Wieser) will discuss commerce media, transparency, and identity topics.
