Jellyfish strengthens media leadership with Seun Odeneye as Chief Media Officer

Odeneye will drive AI-enabled innovation and scale impact across the EMEA Media practice

Global digital marketing business Jellyfish, part of The Brandtech Group, has appointed Seun Odeneye as Chief Media Officer EMEA. The key hire marks a decisive step in Jellyfish’s ambition to build EMEA’s first truly agentic media practice, bringing media, strategy, investment, and content together under one AI-native proposition across the region.

Odeneye brings a broad, 360-degree perspective on the industry, built over a 20-year career spanning media, technology, performance, and investment. He joins from senior leadership roles across IPG Mediabrands, most recently as Managing Director, Investment, where he delivered innovative media solutions that maximised client investment and ROI.

Before that, he served as Managing Director, Media at KINESSO UK&I, IPG’s tech-driven performance marketing agency, where he led a 350+ strong division spanning search, social, addressable, and performance. Earlier career milestones include key roles at Mindshare and Microsoft, where he spent nearly a decade, rising to Head of the Microsoft Performance Network and Mobile Strategy Lead for the UK.

Odeneye will now lead Jellyfish’s EMEA paid and earned media practice, with a mandate to accelerate the agency’s agentic media agenda, pushing the frontier of AI and agentic innovation while elevating Jellyfish’s capabilities across every form of media, strategy, and investment analytics.

The appointment follows Stephanie Parry’s recent appointment as Managing Director, UK & Ireland, reinforcing Jellyfish’s leadership bench as the agency continues to grow its integrated media, creative, and data offering within The Brandtech Group.

Natasha Wallace, Global Chief of Media, Strategy and AI, Jellyfish, said:

“Appointing Seun is a significant step forward for our media offering in EMEA. He brings sharp commercial instinct and operational experience, which is central to bringing to life a unified media, content, and commerce proposition: unlocking the full power of Pencil alongside Jellyfish’s deep performance and investment expertise. Seun’s expertise doubles down on our performance heritage, extending that track record to more brands across every stage of the funnel as AI fundamentally transforms how consumers discover, evaluate, and engage with brands.”

Seun Odeneye, Chief Media Officer EMEA, Jellyfish, said:

“When Natasha approached me about the EMEA Chief Media Officer role, I had long admired how The Brandtech Group and Jellyfish help brands show up authentically across paid and earned channels. In a landscape where AI is increasingly shaping brand perception, media isn’t a silo anymore – it’s the connective tissue between insight and impact. Meeting Steph and Tash completely sealed the deal for me, as I am deeply passionate about collaborating with top talent who believe in putting people, technology, and creativity at the centre of growth.

My focus at Jellyfish is clear: scale our capabilities, embed AI that delivers real outcomes, and help clients win in a world driven by intelligent systems and real-time conversations.”
