ABOUT UPPER CLASH
UPPER CLASH is a roundtable event series in London for leaders in the consumer brand space. Each event is designed for 10 - 30 attendees, creating a focused environment for meaningful conversation and real insight.
Hosted by Leon Bailey-Green, the sessions feature Q&As with senior figures from top retail brands, followed by a moderated group discussion with founders, directors, marketers and e-commerce heads from across the consumer sector.
Over the past year, we've welcomed speakers from brands including H Samuel, Holland & Barrett, Theory, Clarins, Daisy London, Skin Rocks and La Prairie.
The sessions serve to equip leaders responsible for building and growing consumer brands with up-to-date knowledge and fresh perspectives on marketing, e-commerce, retail channels and customer experience.
