Head of Performance Marketing | Challenger eCommerce Brand | London

The Client operates within a fast-evolving consumer category, successfully carving out a distinctive position in the market by challenging conventional approaches and building meaningful relationships with its customers. As a result, the brand has developed a level of customer loyalty and advocacy that has become a key driver of its continued growth.

The company has experienced significant momentum over recent years, expanding its customer base, broadening its product offering, and strengthening its position within an increasingly competitive landscape. Alongside its success across direct-to-consumer channels, the business continues to explore new routes to market and opportunities to further accelerate growth.
