GroupM has hired influential advertising analyst Brian Wieser as its global president of business intelligence.
He joins from Pivotal Research and will report to the WPP-owned media buying agency's global chief executive Kelly Clark.
Branded as the "most quoted man in advertising", Weiser is tasked with building out GroupM's thought-leadership credentials, working with clients to build campaigns on stronger insights.
Clark said: "We are thrilled to welcome Brian to our team. He has deep understanding of economic and industry dynamics, consumer behaviours, media partners, and technology platforms. He is uniquely suited to create insightful analysis that will help our clients make marketing investment decisions.”
Wieser said he joined the agency as "there is no better opportunity to help shape the future of marketing and advertising than this role with GroupM and WPP".
He outlined that the entire industry is being disrupted by tech and that the rules for brands are being rewritten.
He added: "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.”
