Head of Marketing and New Business

Founded in 2013, we are an independently owned experience partner delivering world-class events and experiences for some of the biggest brands across the globe. We partner with forward-thinking, ambitious clients to create impact - whether for a product roadshow, a reimagined B2B conference, a global car launch, or a major industry exhibition. Our ambition is simple: to create human-first experiences that build communities, fuel innovation, spark collaboration, and unlock new opportunities for our clients.

Our approach has earned us places on both The Sunday Times 100 Fastest Growing Company List (#21) and the Business Leader Growth 500 list in 2025. We are also proud to be recognised as a 2025 Sunday Times and Campaign "Best Place to Work". These accolades reflect something we nurture; building success without compromising on people, purpose or standards. We call it 'growth without compromise'.

Sleek is defined by a people-before-profit mindset. We celebrate individuality, set high standards and believe purposeful leadership and exceptional work go hand in hand. Everyone here is self-motivated, curious and committed to growing, regardless of seniority. We value people who take ownership, solve problems willingly, act on feedback, and are comfortable operating in a fast-moving, high-standards environment.

Based in Wimbledon, our HQ is a bright, modern and collaborative space where people genuinely enjoy spending time sharing ideas, playlists, lunch breaks and visits from the office dogs. Being proudly OfficeByDesign, we work from our HQ four days a week with one work-from-home day, plus flexible core hours. This pattern is central to how we work. We know we learn and perform better when we are together – after all, our business is about bringing people together.

Our structure has been consciously designed to enable growth and invest heavily in team development. You will find Sleek a welcoming place for everyone, from those starting their careers to experienced specialists. We are committed to creating a community where you can do your best work and realise your potential. We also expect and welcome candidates from all backgrounds and are here to make reasonable adjustments throughout the interview process wherever needed – just let us know.

We are looking for a Marketing and New Business unicorn to help shape how we position ourselves, generate demand, and convert opportunities. The role exists to help Sleek "grow without compromise" by being the connective tissue between Marketing and Business Development – helping shape how we show up in the world, win new clients, and tell the stories that propel us forward.

This role is ideal for someone who has worked in creative agency environments, likely for 5-6 years, (events experience a plus) who understands how to tell compelling stories, build strong pipelines, manage winning pitch teams and drive growth through targeted and intentional customer journeys.

• PR Lead
• Partnerships Director (responsible for partnership & lead generation)
