Head of Growth (gn) @ D2C Health & Wellness Start-Up, London

Location: London, UK

Type: Full-time
Stage: Venture-backed, post launch

About us

We’re reimagining how people take care of their health - starting with the gut.

Our team brings together science, technology, and brand to create evidence-based products that help people feel and function better every day. Built on patented research and validated through clinical studies, our platform bridges cutting-edge microbiome science with a simple, trusted consumer experience.

Since launch, we’ve supported tens of thousands of customers, established collaborations with leading research institutions and the NHS, and earned recognition from healthcare professionals across the UK.

Now, we’re entering our next phase of growth - expanding our D2C presence, deepening retention, and scaling partnerships - to build the most trusted gut health brand in the world.

If you’re a performance-driven builder excited to scale a mission-led brand from strong foundations to its next growth chapter, we’d love to meet you.

About the Role

We’re looking for a hands-on Head of Growth to own acquisition, retention, and lifecycle performance across the entire D2C funnel.

You’ll partner closely with the founders and product teams to define and execute the growth roadmap - building the playbooks, systems, and creative engine that drive measurable results.

This is a high-impact role for someone who loves data, experimentation, and making things happen fast.

What You’ll Do

• Own key D2C growth metrics - revenue, CAC, LTV, and contribution margin.

• Lead and optimise paid channels - Meta, Google, TikTok, YouTube, influencer, and affiliate marketing.

• Scale lifecycle and retention marketing - drive performance through email, SMS, packaging, and content.

• Own the digital experience - manage CRO, website optimisation, and product merchandising (Shopify).

• Launch and optimise new products, bundles, and pricing strategies - from concept to go-live.

• Partner with product and brand to define the growth roadmap and align campaigns with launches and customer insights.

• Use data to guide decisions - build dashboards, track performance, and forecast growth.

• Collaborate with leadership on growth reporting and investor updates.

• Build and lead a small, high-performance team - managing freelancers, agencies, and creative partners to scale execution.

About You

Skills & Experience

• 5–8 years in growth, performance, or digital marketing - ideally in D2C, health, or consumer goods.

• Proven success running and scaling paid acquisition channels with strong ROI.

• Deep understanding of full-funnel performance and lifecycle marketing.

• Experience with CRO, website optimisation, and e-commerce tools (Shopify preferred).

• Comfortable managing agencies, freelancers, and cross-functional projects.

• Analytical mindset with a strong grasp of growth metrics, experimentation, and attribution.

• Excited to roll up your sleeves and build systems that scale.

How You Work

• You’re hands-on and data-obsessed - you love testing, iterating, and finding signal through noise.

• You act like an owner - balancing commercial impact with brand integrity.

• You thrive in high-growth, fast-moving environments and value speed over perfection.

• You’re curious, creative, and collaborative, and you care deeply about the product and customer experience.

Why This Role Is Exciting

• Shape and scale the growth engine of a proven, science-backed health brand.

• See the direct impact of your work - on business results and on people’s wellbeing.

• Work closely with an experienced founding team in a high-trust, fast-paced environment.
