Healthcare across Europe mainly depends on systems that are still very much reactive in nature, which means they usually come into action after symptoms appear. Preventing diseases is, in most cases, not their primary aim. This situation brings about a major challenge. The most prominent causes of death across the continent are chronic diseases such as cardiovascular disease, diabetes, and metabolic disorders. Many of these conditions develop silently over several years and often leave traceable signals in standard blood tests long before an official diagnosis is made.
Lucis Steps In With a Preventive Approach
Paris-based startup Lucis is confident it can help bridge this gap. The French preventive health company has raised 8.5 million dollars in seed funding to scale regular, structured health testing and early disease prevention across Europe. The round was led by General Catalyst, with backing from Y Combinator, Kima Ventures, Motier Ventures, Circle.Co, and North South Ventures.
Founded in 2025 by Maxime Berthelot, Baptiste Debever, and Max Guerois, Lucis positions itself at the intersection of certified medical testing, clinical oversight, and data driven insights. The startup does not offer consumer health gadgets or self diagnosis tools. Instead, it works exclusively with certified medical laboratories to carry out preventive health check ups.
Empowering Individuals Without Replacing Doctors
“Our objective is to equip people with the means to manage their own health by giving them a clear picture of their main health metrics before seeing the first signs and pairing them with feasible solutions to continue their wellness journey, without substituting doctors,” said Maxime Berthelot, CEO and co-founder of Lucis.
Lucis focuses on improving health understanding rather than offering diagnoses. Its goal is to help users become more informed and proactive while staying aligned with traditional healthcare systems.
Making Complex Data Easy to Understand
One of the biggest problems Lucis addresses is the difficulty of interpreting traditional blood test reports. Patients often receive long, highly technical PDF documents filled with reference ranges and clinical terminology. These reports make it hard to identify what truly matters or what actions to take next.
Lucis replaces this experience with a simple and intuitive digital dashboard. Blood test results are reviewed by a medical team and processed using AI. The system highlights key signals, tracks changes over time, and identifies emerging trends that may require attention. The platform does not deliver diagnoses but instead provides context to help users understand how their biomarkers relate to potential health risks.
Five Pillars of Personalized Guidance
Users receive practical and personalised recommendations across five core areas:
- Nutrition
- Supplements
- Physical activity
- Sleep and recovery
- Mental health
The platform is designed to improve health literacy and enable earlier, more meaningful discussions between patients and their physicians.
“When more Europeans choose to take charge of their own health, this funding allows us to make disease prevention accessible by connecting certified lab analyses, medical expertise, and a clear, user-friendly platform,” Berthelot added.
Competing in a Growing Market
The European preventive health testing market is becoming increasingly crowded. Companies such as Zoī also offer laboratory-based health check-ups in France. Lucis differentiates itself through AI-powered long-term tracking and a five-pillar personalisation model that focuses on behaviour change rather than one-time test results.
By grounding its model in certified laboratories, physician oversight, and longitudinal data, Lucis aims to stay aligned with public health systems and avoid being seen as a quantified self gadget.
Expansion Plans Ahead
Lucis is currently operating in France, the UK, Ireland, and Portugal. The company reports that more than 500,000 tests have already been conducted through its platform. The newly raised funding will support expansion into additional European markets, strengthen partnerships with laboratories and physicians, and further develop its AI technology.
As European healthcare systems face growing pressure from ageing populations and rising chronic disease rates, Lucis is betting that prevention, when made accessible, understandable, and medically grounded, can shift healthcare from reactive treatment to long-term health resilience.
