Senior Marketing Manager (Co-founder in B2C Health App)
About the Role
ONU Health is building the AI-powered future of personal prevention. We unify medical, lifestyle, and wearable data into a single "health account," helping people see risks before they arise and take control of their wellbeing.
We're seeking a co-founding Marketing Manager who can bridge storytelling, community, and growth — turning a preventive health mission into a movement. You'll work closely with our designers and CEO to define how ONU Health is communicated, build our community, and grow our customer base.
Key Responsibilities
🧭 Brand Strategy & Positioning
Define ONU's brand narrative — "Your data, your health, your prevention."
Position ONU between medical credibility and lifestyle inspiration — where prevention feels aspirational, not clinical.
Shape a unified messaging architecture across web, app, and social, highlighting ONU's unique value: predictive, data-driven, and privacy-first.
Work with designers and the CEO to establish ONU's visual and verbal identity across all channels.
📊 Social Media, Funnels & Campaigns
Own social media strategy and content calendar — building ONU's presence and voice across key platforms.
Design and run campaigns that build brand awareness and drive customer acquisition.
Build and optimize multi-channel acquisition funnels (content, influencer partnerships, paid social, and Apple Health integrations).
Develop onboarding journeys, email/push automations, and retention loops tied to users' health improvements.
Track activation, retention, and referral metrics to continuously refine messaging and campaign performance.
💬 Community & Thought Leadership
Create the ONU Health Founding Member Program and early adopter community.
Grow and nurture ONU's customer list and community channels.
Collaborate with medical advisors and creators to launch educational campaigns around prevention and self-tracking.
Drive storytelling across channels (press, social, product updates) to humanize complex AI health concepts.
Requirements
Experience in social media, brand, or growth marketing, ideally in digital health, fitness, or consumer SaaS.
Proven experience building campaigns and funnels that grow an audience or customer base, ideally for an early-stage product.
Strong understanding of healthtech positioning, user psychology, and trust building (especially for sensitive data products).
Analytical and creative mindset — fluent in both storytelling and metrics (CAC, LTV, retention).
Comfortable working closely with designers and founders to shape brand identity from the ground up.
Passion for preventive health, data-driven wellness, and AI-enabled personalization.
Benefits
Equity: based on experience and time commitment, as a co-founding role.
Vesting: 4 years with 1-year cliff.
From February: Future Salary Post-funding (March 2026).
Equal say in product and roadmap decisions alongside founders.
Flexible schedule (20–30 hrs/week possible; past funding to full-time).
Remote-first (EU time zones preferred).
ONU Health is a HealthTech startup from Berlin. We're building a smart "health account" — a secure platform for storing and analyzing medical data: test results, diagnoses, medications, and personal health goals. Using AI, we provide personalized recommendations and help people better understand their health. We are not a medical product and do not provide diagnoses.
Our team already includes four people — developers, designers, and a project manager. We're a close-knit, ambitious team building the future of preventive health.
