I’ve long admired Kantar’s ability to turn insight into brand and business impact, and I’ve seen first-hand the high regard in which marketing leaders hold the business. Unique assets like BrandZ and the Meaningful, Different and Salient (MDS) framework are not just differentiators – they’re trusted tools marketers use to shape meaningful growth.”
