Head of Growth Marketing - Testosterone Replacement Therapy

Voy is a leading preventive healthcare platform for men and women, with core clinical pathways across weight management, hormone treatments, dermatology and mental health. The business is scaling fast - $675m annualised revenue, growing ~130% YoY, operating across the UK, Brazil, Germany and India. Within Voy, the Testosterone Replacement Therapy (TRT) category is one of our fastest‑growing and most strategically important lines. We're the largest private TRT provider outside the US, with 250,000+ men tested for low testosterone, a published outcomes study with Harvard Medical School covering 9,500 patients, and a clinical authority team led by Dr Jeff Foster (co‑author of the UK's national testosterone guidelines). Despite that, TRT in the UK sits roughly where female HRT did a decade ago: clinically common, culturally stigmatised, and largely absent from mainstream conversation. The category is on the cusp of a cultural shift, and we intend to lead it.

We're hiring a Head of Growth Marketing to take the TRT category from where it is today to category‑defining scale – building both the acquisition engine and the cultural conversation that gets us there. You'll have full ownership of growth strategy, a meaningful budget, and the chance to build the team and infrastructure to match the ambition. This is a rare role: the commercial scale and operational rigour of a $675m business, combined with the category‑defining mission of changing how the UK talks about men's hormone health.

What You’ll Be Doing

• Own the overarching growth plan, achieving 100% yoy growth in acquisitions.
• Lead the growth marketing strategy for category awareness and stigma reduction – partnering with PR and clinical teams to translate cultural relevance into measurable acquisition outcomes.
• Lead end‑to‑end creative campaign development – from concept through media planning, creative production, and performance optimisation.
• Act as the primary growth‑side client for our PR agency – defining objectives, measuring impact on acquisition, and ensuring patient stories, clinical research, and celebrity partnerships translate into commercial outcomes.
• Own the integrity of the patient experience from first impression to activation – driving alignment with product, lifecycle, and operations to ensure the funnel converts efficiently end‑to‑end.
• Own the P&L for paid and earned acquisition – accountable for CAC, payback period, contribution margin, and revenue contribution to the category.
• Define where the next growth will come from – identifying whitespace, emerging channels, and new audience bets before they're obvious.
• Set acquisition targets and growth investment plans in partnership with Finance, defining the unit economics, payback expectations, and budget allocation that underpin the category P&L.
• Serve as the senior voice on growth in cross‑functional planning, influencing product roadmap, pricing, and GTM decisions.

Healthcare is broken. We’re fixing it — and we need your help. Back in 2019, we launched MANUAL to tackle men's health (starting with hair loss and sexual health). A few years later, we launched Voy with a focus on weight loss. But our ambition has always been bigger. Healthcare too often treats conditions in isolation, not people as a whole, and we're on a mission to prove there's a better way. In 2025, we evolved from MANUAL into Voy, a brand built for the long game: supporting people through every stage of life, not just a single diagnosis. Today, we support over 1 million members across the UK, Germany and Brazil, delivering personalised care across weight loss, menopause, hair loss and TRT (with more categories on the way).
