Lucis turns regular blood tests into actionable health insights
Hey YC 👋
We’re Max B, Baptiste, and Max G - co-founders of Lucis.
Lucis turns regular blood tests into actionable health insights - so people can act before it’s too late. In 4 months, we’ve helped 500 people in Paris get ahead of chronic diseases. Today, we’re expanding across Europe.
85% 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.
Those 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.
“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.”
Lucis 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.
You’ll get answers to questions like:
"Am I aging faster than I should?"
"Is my testosterone at a healthy level for my age?"
"How can I improve my next marathon performance?"
Here’s how it works:
We started Lucis because we’ve lived the problem ourselves.
Baptiste 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.
Lucis is what we wish we had - and now, we’re building it for everyone else.
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.
We 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.
