Jon Holm

Jon Holm is best known in the AdTech industry as the creator of ATDb (The Advertising Technology Database), a self-initiated intelligence platform designed to bring structure and clarity to the fragmented landscape of advertising technology. By cataloging the platforms, tools, and infrastructure powering modern advertising, Holm has positioned himself as a practitioner-turned-cartographer of the AdTech ecosystem — a rare combination of hands-on operator and industry organizer. In his day-to-day role at Comcast Advertising, Holm manages a team of ad strategists and account specialists serving California markets including San Francisco, Sacramento, Monterey, and Fresno. His work centers on addressable advertising, cross-platform measurement, and competitive strategy, with a strong emphasis on leveraging Comcast's first-party household data to deliver targeted client solutions in the evolving convergent TV and digital media environment. Holm's expertise spans programmatic advertising, advanced TV, and data-driven audience solutions. His creation of ATDb reflects a broader commitment to industry education and transparency — an effort to help practitioners, buyers, and vendors better understand how the increasingly complex AdTech stack fits together. This initiative distinguishes him as both a working operator within a major media company and an independent contributor to AdTech industry knowledge.
