Today, we’re expanding across Europe.\n\nhttps://youtu.be/a5fX1K5hnvU\n\n### **The Problem In Europe**\n\n85% of deaths are caused by preventable chronic diseases. That’s more than 4 million lives lost every year just in Europe. Yet, the healthcare system remains reactive, and people receive care only after something goes wrong.\n\nThose seeking comprehensive preventive care, including blood testing, analysis, and expert guidance, typically resort to private longevity clinics that charge over €50K per year. **Such premium healthcare remains inaccessible to the vast majority of people.**\n\n### **Lucis: Health Insights in Your Pocket**\n\n_“If you're tired of being in the dark about your health, not knowing where you stand or what to do next, Lucis is built for you.”_\n\nLucis goes beyond vague checkups and unreadable lab reports. It provides a clear health baseline, tracks progress over time, and translates complex biomarker data into personalized guidance people can actually implement in their daily lives. All at a fraction of the cost of a private clinic.\n\nYou’ll get answers to questions like:\n\n_\"Am I aging faster than I should?\"_\n\n_\"Is my testosterone at a healthy level for my age?\"_\n\n_\"How can I improve my next marathon performance?\"_\n\n![uploaded image](/media/?type=post\u0026id=90454\u0026key=user_uploads/1454634/0a347d82-7c9b-4fef-8c72-bf70511ce761)\n\nHere’s how it works:\n\n* 2 full health check-ups per year\n* See how your body’s doing with 15 health scores and your biological age - and track your progress over time.\n* Personalized action plan across nutrition, sleep, and movement\n* Access to longevity add-on tests, like microbiome, continuous glucose monitoring, and food sensitivity tests.\n\n### **The Team**\n\nWe started Lucis because we’ve lived the problem ourselves.\n\nBaptiste lost a close relative to a condition that could’ve been caught earlier. Max B has spent the last decade deep in biohacking, testing everything from supplements to wearables. At 27, Max G turned his health into an experiment - tracking sleep, diet, and training - and improved nearly all of his biomarkers in the process. We know what it’s like to search for clarity and get none.\n\n**Lucis is what we wish we had - and now, we’re building it for everyone else.**\n\n![uploaded image](/media/?type=post\u0026id=90454\u0026key=user_uploads/1454634/830d7470-4a85-446e-b427-38ec7343d441)\n\n### **Since launching our beta just 4 months ago:**\n\n* **30,000+ people** have joined our European longevity community.\n* **30+ lab locations** opened across France\n* **2 new European cities** - now live in Lisbon 🇵🇹 and London 🇬🇧\n* **500+ people in Paris** used Lucis to get ahead of chronic illness\n* **10 AI Startups** have gifted Lucis as a health benefit for their employees\n\n## \n\n### **Our Vision**\n\n**Lucis isn’t just a product - we’re building a completely new healthcare system in Europe.** One that lives with you. And works for you quietly, every day.\n\nWe started with blood, but our ambition goes far beyond a single input. We are building Lucis, the intelligence layer for your health. Right in your pocket.\n\n### **Ask**\n\nIf this resonates with you\n\n* Know someone in Europe who wants to live 100 healthy years?
