Seedtag Appoints Brendan McCarthy as New Chief Marketing Officer to Drive Growth
In a significant move to bolster its global marketing strategy, Seedtag has appointed Brendan McCarthy as its new Chief Marketing Officer. McCarthy, who previously served as CMO at Criteo, brings over two decades of experience in strategic marketing and communications from Fortune 500 companies such as Nielsen, Samsung, and eBay. His role at Seedtag will focus on refining the company’s marketing and communication strategies, particularly as it aims to enhance its Neuro-Contextual advertising approach.
Seedtag has seen tremendous growth, with a reported 46% increase in year-over-year revenue in North America during 2025. This growth trajectory has been largely driven by its innovative AI platform, Liz, which utilizes neuroscience to decode real-time interest, emotion, and intent to deliver relevant, privacy-first advertising. McCarthy's leadership will be instrumental as the company seeks to expand its reach and impact further.
As Brian Gleason, CEO of Seedtag, noted, the future of advertising is shifting from tracking individuals to understanding their needs. McCarthy's ability to blend creativity with data-driven insights positions him uniquely to help Seedtag meet its goals. He will lead a global team dedicated to enhancing brand visibility while aligning marketing and communications efforts to maximize growth.
The timing of McCarthy's appointment could not be more strategic, as Seedtag aims to disrupt traditional advertising norms by implementing innovative solutions that prioritize consumer trust. By aligning its brand strategy more closely with its business objectives, Seedtag aims to create deeper connections with audiences and provide measurable impacts for its clients.
At Seedtag, the belief is that as they expand internationally, they must not only maintain their momentum but also push towards becoming the leading AI-driven partner for brands that prioritize innovation. As McCarthy steps into this pivotal role, the advertising landscape is set to undergo further transformations driven by advanced contextual insights and a focus on privacy-first advertising practices.
Seedtag's Neuro-Contextual platform, supported by Liz, is designed to create more relevant advertising experiences. This environment stands to benefit both advertisers looking to connect with consumers in a meaningful way and publishers striving to maximize the effectiveness of their content. As global consumer expectations continue to evolve, McCarthy's extensive background in tech-driven marketing will be crucial in navigating these changes and fostering growth.
Founded in 2014, Seedtag has rapidly evolved, establishing a robust presence in New York City and Madrid. With a global workforce of over 700 professionals spread across regions including EMEA, LATAM, North America, and APAC, the company is well-positioned to capitalize on the growing demand for innovative advertising solutions. McCarthy's leadership will likely prove to be a key element in accelerating Seedtag's growth and solidifying its position as a leader in Neuro-Contextual advertising.
In conclusion, as Brendan McCarthy steps into his new role at Seedtag, the industry can anticipate an invigorated approach to advertising that emphasizes not just reach, but also the depth of connection between brands and their audiences. The focus on understanding consumer behaviors through advanced AI and neuroscience will undoubtedly shape the future of advertising strategies across various platforms. McCarthy's appointment is a strategic move for Seedtag as it prepares for the next phase of growth and transformation in the marketing landscape.
