Head of Marketing in London

ABOUT US

What if stress wasn't the enemy of performance, but the key to unlocking it? WONE is a human performance company building stress intelligence for high-performing organizations. Built with experts from Harvard, Stanford, and Mayo Clinic, WONE combines the world's first validated measure of stress resilience with an AI performance coach that brings together AI technology and human intervention to turn everyday stress into a measurable performance advantage. The results speak for themselves: 74% of users report lower day-to-day stress, 90% report improved productivity, 40% company-wide engagement, and our clients see 5x ROI. We partner with global enterprises including Arm, Cantor Fitzgerald, and Quinn Emanuel, and we're backed by Octopus Ventures, Notion Capital, Arianna Huffington, and Brent Hoberman. Our leadership team brings experience from Google, Treatwell, Deliveroo, and BenevolentAI. We live and breathe our mission from the inside out, with wellbeing genuinely at the core of how we work together.

ABOUT THE ROLE

WONE has unique science, product, and enterprise validation. We have a mission and brand that is already category-defining with huge potential. We are now looking for an owner of the marketing function who can leverage these strong foundations to build our category leadership and turn that category authority into a strong, systematised inbound pipeline for the sales team. This role owns the entire marketing function end-to-end, including line management of the marketing team. Our 2026 goal is to own stress intelligence as a category, reframe stress from something to avoid talking about into one of the most necessary ingredients of high performance, and make WONE the brand people instinctively reach for when they think about performing under pressure.

• Demand generation and pipeline: You will own inbound strategy and paid media across LinkedIn and Google, develop nurture journeys and lead magnets to support pipeline growth, define MQL criteria and manage the handoff process to sales, and partner closely with the sales team to co-own outbound strategy and pipeline generation.
• Product marketing: You will lead GTM strategy for new product features such as Ori and the WONE Index, and own positioning, messaging, and persona development across CHRO, Head of Benefits, and CFO audiences.
• Sales enablement: You will create and maintain pitch decks, one-pagers, objection-handling materials, ROI calculators, and case studies.
• Website, SEO, analytics: You will own editorial direction and authority across website copy, lead content and technical SEO strategy, and improve AI search visibility and full-funnel attribution across marketing channels.
