She has built a reputation within UK AdTech circles for her practical, operations-grounded perspective on issues including supply path optimization, brand safety, and the detection and mitigation of made-for-advertising inventory. Her work sits at the intersection of day-to-day ad operations and broader industry standards conversations, making her a credible voice bridging holdco agency practice with ecosystem-wide transparency efforts. Gleeson's career has been shaped by the rapid evolution of programmatic buying within large agency networks, giving her hands-on experience with DSP management, audience strategy, and the increasingly complex supply chain dynamics that define modern biddable media. Her focus on SPO and MFA detection reflects a broader industry shift toward quality and accountability in programmatic spend, areas where agency operators like Gleeson play a critical role in translating policy into practice. As a representative of a major holding company agency, Gleeson's influence extends beyond internal operations to industry dialogue, where she contributes perspectives on how large-scale advertisers can navigate transparency challenges in programmatic ecosystems. Her dual focus on tactical execution and strategic standards positions her as a practitioner-thought-leader hybrid within the UK AdTech community.
