GroupM Names Nick Slaymaker Deputy Head of Global Investment

New York (July 26, 2022) — GroupM, WPP’s media investment group, today announced that Nick Slaymaker will be transitioning into a newly created role as Deputy Global Head of Investment, effective immediately. His core responsibility will be to lead GroupM’s investment activation strategy and implementation. He will report to Andrew Meaden, GroupM’s Global Head of Investment.

“Nick brings long experience on both the agency and GroupM side across EMEA and APAC, and his acute strategic business sense, combined with a commitment to clients and culture, will be a major advantage for our agencies and clients,” said Andrew Meaden, Global Head of Investment, GroupM. “Given the pivotal role Nick played in helping MediaCom achieve the immense success it has over the last couple of years, he’s the right fit to now help support GroupM’s investment practice and our clients.”

Slaymaker comes to GroupM from his role as Chief Investment Officer for MediaCom, where he oversaw client affairs across pricing management, commercial terms management, as well as crucial client and consultant handling. He has been heavily involved in many of MediaCom’s recent marquee wins and will now bring that experience to GroupM.

“I am excited for an opportunity to not only join GroupM’s leadership team and work alongside Andrew but also to continue to build relationships with current and potential clients that help grow our business and theirs even further,” said Slaymaker. “It has been a big first half of the year for GroupM with the announcements around GroupM Nexus, the agency restructures, our extraordinary wins at Cannes, and not least of all topping the COMvergence rankings for Global Media Company yet again. I am passionate about continuing to work to strengthen the position of GroupM and our agencies and to accelerate our impact across the world.”

Slaymaker will be based in London.
