What We Do
"One of the things that’s most important is that GroupM takes a leadership position in making advertising work better in the world."
Christian JuhlCEO, GroupM Global
We’re a people business with experts passionate about media, technology, brands and audience engagement. Because media never stops evolving, we continuously learn with clients and partners to understand the most effective paths to consumer engagement with brand messaging.

Strategy and Business Development
"We help brands reach their consumers with the right messages on their path to purchase, at the right time and in the right context."
Elizabeth McCuneChief Growth Officer, GroupM Global
To achieve brand growth, we believe a winning strategy begins with precise audience insights.

"Media is increasingly important in customer relationship management.

We help them do this with data and technology shaped to their unique needs. "
Colin BarlowCOO, GroupM Global

Our worldwide team of analysts, data strategists and media specialists activate this intelligence to help make brands more meaningful to consumers in their target audience.
"As advertisers move more of their investments from linear to digital mediums, they need assurance their brands are being seen by real people, not bots, in the right audience target, and in an appropriate environment."
John MontgomeryEVP of Brand Safety, GroupM Global
Consumer adoption of digital and social media platforms has enabled incredible opportunities for brands to connect directly with their consumers, but there are risks.

Rightly, they also deserve standards and measures that support accountability and create trust.
