Bryan Wiener is one of AdTech's most seasoned transformation executives, known for repositioning legacy and distressed businesses into modern, data-driven marketing platforms. As CEO of Quad since 2021, he has led the company's strategic evolution from a traditional commercial printing operation into an integrated marketing experience company with growing capabilities in retail media networks, performance marketing, and data analytics — making Quad a compelling alternative to holding company agency models for brand marketers. Before Quad, Wiener served as CEO of Comscore from 2018 to 2021, stepping in during a period of significant financial and governance turmoil to stabilize and refocus the digital measurement company. His tenure at Comscore demonstrated his ability to navigate complex stakeholder environments while maintaining the company's relevance as a currency for cross-platform audience measurement. Earlier in his career, Wiener spent over a decade building 360i from a search-focused boutique into one of the most awarded and respected independent digital agencies in the U.S., before its full integration into Dentsu's network. With more than 25 years spanning digital marketing, agency operations, measurement, and marketing technology, Wiener brings a rare combination of creative agency sensibility and data-platform rigor. He is widely regarded as a pragmatic operator who understands both the brand marketer's perspective and the infrastructure required to deliver measurable outcomes at scale.
