Head of Marketing | D2C Fitness Brand | London / Hybrid in Slough

Our client is a rapidly growing direct-to-consumer fitness brand redefining how consumers engage with health, performance, and everyday wellbeing. Built around premium products, an engaged customer community, and a strong mission-led identity, the business has established itself as one of the most exciting brands within the modern fitness and wellness space. Over the last few years, the company has built a loyal customer base through a combination of innovative products, authentic storytelling, and a highly engaged audience. As the business enters its next phase of growth, the opportunity is to evolve from a founder-led marketing approach into a fully integrated marketing function capable of driving brand awareness, customer engagement, and long-term market leadership.

With increasing competition across the fitness landscape and growing opportunities across digital, retail, partnerships, and community channels, the focus is now on building a cohesive marketing strategy that strengthens brand equity while supporting ambitious commercial growth objectives. The business is now seeking a Head of Marketing to lead the development and execution of its marketing vision. This is a highly influential leadership role working closely with the founders and senior leadership team, with responsibility for shaping brand strategy, campaign planning, customer engagement, and marketing performance across all touchpoints.

• Someone who combines strong analytical thinking with excellent marketing instincts and customer understanding.
• A strategic operator who is equally comfortable setting direction and rolling up their sleeves to solve problems.
