Contextual advertising firm Seedtag has appointed Brendan McCarthy as chief marketing and communications officer.
McCarthy will oversee Seedtag’s global marketing and communications strategy. He will support the company’s international expansion while driving the evolution of Neuro-Contextual advertising across the open web and CTV.
McCarthy joins Seedtag following his tenure as chief marketing officer at Criteo. At Criteo he helped transform the company’s positioning from a single-product point solution to the leading AI-centric commerce media platform.
He brings more than 20 years of strategic marketing and communications experience with Fortune 500 companies, blending data, creativity and thought leadership to deliver measurable business impact.
Brian Gleason CEO of Seedtag said: “At Seedtag, we believe the future of advertising isn’t about tracking people— it’s about understanding them,”
“Brendan brings the rare ability to turn vision into momentum and innovation into impact. As we expand Liz and our Neuro-Contextual platform globally, his leadership will help brands connect with audiences in more meaningful, measurable ways.”
McCarthy will lead a global team focused on advancing the company’s brand, driving demand, and aligning marketing and communications as an integrated growth engine. His appointment comes at a pivotal moment for Seedtag, amid continued global growth and momentum fueled by its proprietary AI platform, Liz.
McCarthy said: “Seedtag has proven it can disrupt the status quo with a years-long track record of rapid growth in mature advertising markets,”
“I’m confident we can accelerate that momentum by aligning our brand and global communications to drive even more value for our clients. We have a unique opportunity to lead the category as the premier AI-driven partner for brands that value both innovation and consumer trust.”
