Bonnie Hatcher is the Co-founder and Chief Marketing Officer of Evelyn Health, a UK based women’s health platform focused on PMS and PMDD support. Her work sits at the intersection of brand strategy, community building, and evidence-based health, and it’s making a real difference in a space that medicine has historically underfunded and underserved.
She came to this mission with a clear trigger: the average PMDD diagnosis takes 12 years. That statistic shaped the direction of her work and the platform she co-built to address it.
Her Career Before Evelyn:
Hatcher’s marketing career spans high-growth consumer brands including Boden and BrandAlley, followed by senior leadership roles at British Military Fitness and Purple Stag Marketing. These were fast-paced environments where she developed a direct, data-informed approach to brand building.
In 2019, she co-founded Unicorn Studio, a marketing agency designed to turn purpose-driven ideas into scalable businesses. From there, she moved into a Managing Director role at ZAG Drinks, where she led the brand’s positioning in the alcohol-free market. She joined ZAG after the agency had worked with them, stepping into the MD role just as she had decided to close Unicorn Studio.
What She Does at Evelyn:
At Evelyn Health, Hatcher owns the entire marketing and growth function. She personally engages with customers via Instagram and WhatsApp, actively seeking community feedback to keep the brand accurate and grounded.
Her approach to marketing in the women’s health space is deliberate. She describes the strategy as one of radical honesty, stating that subtle messaging does not work in this category, and that direct, anatomical language is what reduces stigma.
Evelyn Health won Women’s Health Start-Up of the Year 2025, a recognition that reflects how far the brand has come since its early days.
The Problem She Is Solving:
The numbers behind Evelyn’s mission are hard to ignore. PMS affects up to 85% of women, while around one in 20 women experience PMDD. Despite that scale, access to proper care remains limited, with many women unable to get meaningful GP support.
Hatcher points out that nearly 80% of women experience premenstrual symptoms, yet 84% feel ignored by healthcare professionals. That gap between lived experience and clinical recognition is exactly what Evelyn was built to address.
Products and Community Work:
Evelyn operates across two tracks: science-backed products and community education. The platform offers evidence-based, non-hormonal support for PMS and PMDD, with supplements formulated by doctors, nutritionists, and women’s health specialists.
In December 2025, Evelyn launched The PMS Bar, which it positions as the first snack bar specifically formulated for the luteal phase of the menstrual cycle. The bar contains 11 active ingredients, including L-tryptophan, magnesium, complex carbohydrates, and prebiotic fibre. Hatcher described the goal simply: to make science-led care practical and something women can reach for at the exact moment symptoms hit.
Beyond products, Evelyn runs a podcast called “Is Anybody Listening?” where women share their experiences with PMS and PMDD, covering topics from diagnosis delays to the emotional toll of living with these conditions. It is part of how the brand builds trust and drives awareness at the same time.
Her Perspective on the FemTech Market:
Hatcher is frequently cited as a voice on where women’s health and nutrition are heading. She argues that cycle syncing is not a new trend but a return to something women have always known, backed now by scientific validation and digital visibility.
She is also clear about what responsible innovation in this space requires. Her direct advice to manufacturers: do not just label a product “for your cycle” and call it innovation. Invest in formulation, partner with experts, and understand the emotional and physiological nuance of this market.
That clarity, backed by years in consumer marketing and a platform built from the ground up, is what makes her a credible voice in the FemTech conversation. Founders and operators building in women’s health would do well to pay attention to how she approaches both product development and community strategy at Evelyn Health.
