In this episode of The Drum Network Podcast we dive into what it takes to rapidly grow a brand without losing what makes it unique. Our guests flag up everything from Salt Bae to Unilever in order to determine the role purpose plays in growing a brilliant brand, where tech empowers and restricts growth, and which sectors we expect to see a new challenger brand emerge from next. Senior reporter for The Drum Chris Sutcliffe is joined by Daniel Liddle, SEO lead at Impression; Amanda Glasgow, creative director EMEA at Appnovation; Mel Henson, head of creative at Optimizon; and Marcus Foley, co-founder and chief growth officer at This Is Tommy.
