Why Lucis?
Lucis is building Europe's first preventive health platform: from blood testing to advanced AI-driven insights and action plans.
We already serve 4,000+ paying members in 🇫🇷, 🇵🇹 and 🇬🇧, growing 10% week over week, and integrating with dozens of lab partners.
- Team of ~17 passionate, tier-1 operators
- Backed by YC X25 and a seed round led by tier-1 investors, athletes & operators
- A live AI "doctor" agent already shipping actionable protocols every day
We're a small, ambitious team of repeat founders and biohackers.
Our founding team members include ex Algolia, ex Padoa, ex Instacart, ex Alan, with experience scaling companies from 0 to millions of users.
Paris-based and YC-backed (X25), we're funded by a top-tier global VC, a specialised healthcare fund, athletes, and serial entrepreneurs, including the founders of Airbyte, Strapi, Sqreen, WePay, Plato, Veepee, and Zenly.
The role
As our Founding lead marketer, you’ll architect the strategy and lead the charge as Lucis expands preventive health across Europe. This is a high-impact, highly strategic role for a seasoned operator, someone who thrives at the intersection of growth, brand, and health, and wants to play a pivotal part in scaling a category leader.
On the day-to-day, you’ll:
- Define and own the GTM roadmap—from channel selection and positioning, to sequencing launches and driving both D2C and B2B growth.
- Build, launch, and optimize campaigns across organic, paid, content, expert/influencer, and corporate wellness channels.
- Partner closely with our medical and product teams to ensure clinical rigor and regulatory alignment, translating science and best practice into compelling, actionable user journeys.
- Drive user acquisition, activation, and retention across multiple European markets (France, UK, Portugal), customizing approaches for each local context.
- Scale our expert and influencer programs, unlocking community-driven growth and trusted word-of-mouth.
- Lead strategic partnerships: identify, pitch, and close B2B deals with top employers, health networks, and labs.
- Own key growth metrics—setting targets, building dashboards, and running regular reviews with the founding team.
- Shape Lucis’ narrative in the health space—positioning us as the leader in AI-driven, preventive health.
You’ll thrive here if you:
- Bring 5/7+ years in senior GTM, growth, or marketing roles, ideally at the intersection of health, D2C, and technology.
- Have a proven track record of launching and scaling consumer health or wellness products, with hands-on ownership of growth levers.
- Understand how to build trust in health—balancing bold storytelling with scientific credibility and compliance.
- Are a true collaborator, able to partner deeply with clinicians, product, and data teams to turn medical insight into user value.
- Think strategically but move fast—comfortable balancing immediate growth with long-term vision.
- Are analytical, data-driven, and relentless in your pursuit of product-market fit and operational excellence.
- Are passionate about health, prevention, and making a real impact on people’s lives.
- Are fluent in English and French.
Our culture
We are building fast, for the long term.
- Rigor without ego: audits, science, and code deserve the same high bar.
- Default to action: small PRs, short feedback loops.
- Radical ownership: you break it, you fix it (and write the doc).
- Play long games: we’re building a 100-year company to help people live 100 healthy years.
