Seedtag names Brian Gleason as global CEO
Seedtag has appointed Brian Gleason as its new global Chief Executive Officer, effective 1 August 2025, as the company enters its next chapter of international expansion and deepens its investment in neuro-contextual advertising. The move follows continued momentum for the adtech company in key markets including the Middle East, where Seedtag has expanded its AI-powered contextual solutions for regional brands and publishers.
Gleason brings close to two decades of leadership in digital media and adtech, having previously held senior roles at Criteo, GroupM (now WPP Media), [m]PLATFORM and Xaxis. He was instrumental in shaping Criteo's commerce media strategy and scaling global data-driven operations.
'I am incredibly excited to join Seedtag at such a pivotal time in the advertising industry,' Gleason said. 'This is a transformational moment with AI at the center of that evolution. Seedtag's neuro-contextual AI approach is groundbreaking, which establishes the company as a pioneer in deeply understanding audience interest, emotion, and intent across CTV and open web. I look forward to working with this talented team, continuing to accelerate our global growth, deliver unparalleled value to our clients, and continue pushing the boundaries of privacy-first advertising.'
Founders and co-CEOs Jorge Poyatos and Albert Nieto will transition into new roles as Chief Innovation Officer and Strategic Advisor, respectively, while continuing to serve on Seedtag's board of directors.
Commenting on the leadership change, Jorge Poyatos, co-founder and Chief Innovation Officer, said: 'The world and our industry are in a period of profound transformation, I am convinced that my new role will allow me to maximize my contribution to Seedtag. Our progress in Agentic AI combined with the addition of Brian as CEO put us in a very unique place to define how the next decade of adtech will look.'
Albert Nieto, co-founder and now Strategic Advisor, added: 'Leading Seedtag as co-founder and co-CEO has been the most rewarding journey of my professional life. Building this company with Jorge and our incredible Seedtaggers has been an experience I'll always cherish and a legacy we're incredibly proud of. With Brian now leading the company, I'm confident Seedtag is ready for its next leap.'
The appointment comes as Seedtag continues to scale its proprietary AI platform, Liz, across channels including CTV and the open web – offering privacy-safe, full-funnel targeting rooted in emotion, intent and interest.
