July 1, 2026 (New York, NY) — EMARKETER today announces the hiring of Vincent Létang, formerly of MAGNA, as Managing Director, Ad Buyer Insights.  The announcement comes just weeks after EMARKETER added Stephanie Paterik as VP, Insights, and continues to strengthen their research talent.

Létang joins EMARKETER at a pivotal moment for media and brands. Commerce Media Networks (CMN) are expected to attract $84 billion in advertising spending in the U.S. this year, up 22% over last year.  CMNs will capture 20% of total US digital ad spending in 2026, while a plethora of platforms are competing to challenge the dominance of Amazon. Meanwhile, CTV advertising will expand by 15% this year, driven by rapidly-growing ad-supported streaming penetration and advertisers keen to follow audiences in their migration from linear TV. Drawing on 25 years advising media and advertising leaders internationally, Létang will work directly with senior executives at commerce media networks and streaming platforms to translate EMARKETER’s proprietary Ad Buyer Insights data into actionable revenue strategies, sharper go-to-market approaches, and deeper advertiser engagement.

“Vincent brings a rare combination of strategic insight, industry expertise, and deep relationships across the advertising ecosystem,” said Matthias Braun, CEO at EMARKETER.  “With nearly 75% of this year’s commerce media growth set to go to just two companies – Amazon and Walmart – the category, combined with CTV, will continue to reshape the advertising landscape.  Létang’s experience will help our clients unlock new growth opportunities in both areas and maximize the value of EMARKETER’s industry-leading data and research.”

In the role, Létang will partner with prospective and existing clients to surface the competitive intelligence embedded in EMARKETER’s Ad Buyer Insights and platform, building strategic roadmaps, and providing ongoing counsel tailored to the specific challenges commerce media and streaming businesses face. His work will be grounded in direct feedback from more than 800 ad buying decision-makers, giving clients a clear view into how platforms are evaluated, selected, and funded.

“Commerce media and CTV are the fastest-growing advertising channels today,” said Létang. “I am excited to join EMARKETER and help navigate this evolving and competitive environment, leveraging EMARKETER’s proprietary insights on ad buyers’ behavior and expectations.”

The appointment reflects EMARKETER’s continued investment in expanding its advisory capabilities and its commitment to delivering strategic value, beyond just data, to clients across the media, retail, technology, and advertising sectors. In addition to Ad Buyer Insights, EMARKETER recently announced its new AI Visibility Index, supporting brands in their need to understand and optimize their position within AI generated results.
