Brian Wieser Joins GroupM as Global President, Business Intelligence


New York, NY, February 6, 2019 – GroupM, WPP’s world-leading media investment group, today announced that Brian Wieser is joining its senior leadership team as Global President, Business Intelligence. Starting this week and reporting to Global CEO Kelly Clark, Wieser will drive and expand GroupM’s thought leadership practice. He will collaborate with GroupM’s agencies and WPP’s broader network to gather, analyze and distribute actionable marketplace intelligence that gives clients insights on markets, audiences, partners and platforms, and supply and demand dynamics.

“We are thrilled to welcome Brian to our team,” said Clark. “He has deep understanding of economic and industry dynamics, consumer behaviors, media partners, and technology platforms. He is uniquely suited to create insightful analysis that will help our clients make marketing investment decisions.”

Wieser is highly regarded in the marketing, media, advertising and technology fields. He has been called “Madison Avenue’s de facto Chief Economist.” In his most recent role as Senior Analyst at Pivotal Research Group, he led the firm’s deep coverage of agencies, video and other digital content platforms, advertising and marketing technology, measurement companies, and more. One of the most quoted executives in the industry, he is sought after by journalists for the deep understanding he developed as an industry analyst and in earlier roles as an advertising and investment banking executive. Previously, Wieser was EVP, Global Director of Forecasting for Interpublic’s Magna Global, CMO for venture-funded Simulmedia, investment banker at Lehman Brothers, and research analyst at Deutsche Bank (covering entertainment and cable).

“There is no better opportunity to help shape the future of marketing and advertising than this role with GroupM and WPP,” said Wieser. “The entire advertising industry is dealing with the consequences of technology-driven disruption, and every day the rules for how brands go to market are being rewritten. For nearly eight years at Pivotal, I’ve been connecting with every corner of the market to evaluate how the major players are leading – or reacting – to this change. I’m excited to use this experience and insight at GroupM and WPP to help clients grow.”
