Lucis is a preventive-health platform based in Paris that turns regular blood tests into AI-assisted, clinician-reviewed action plans across nutrition, supplements, activity, sleep, and mental health. Members get blood drawn at partner labs across Europe; Lucis analyzes an extensive biomarker panel and presents a longitudinal dashboard rather than a one-off PDF, focusing on prevention and education instead of diagnosis. The platform integrates AI insights with clinician review to tailor ongoing guidance, supported by a network of labs and physicians. Lucis differentiates itself from typical lab services by offering continuous monitoring through a multi-year dashboard and actionable plans rather than isolated reports. Its goal is to help people prevent health issues by providing lasting, education-forward guidance that empowers lifestyle changes, backed by professional oversight.

Lucis, a preventive healthcare platform, has raised $20 million in Series A funding led by Singular, with participation from General Catalyst, Y Combinator and angel investors. The round follows an $8 million seed raised four months ago, bringing total funding to $28 million. Founded in 2025 by Maxime Berthelot and Baptiste Debever, Lucis analyses over 110 blood biomarkers and uses AI-powered insights reviewed by physicians to deliver personalised health guidance. Among users completing six-month follow-ups, 75% improved at least three biomarkers without medication, whilst over 80% opted to retest. The platform has reached 10,000 users across France, the UK, Ireland and Portugal, delivering over one million biomarker tests. Lucis plans to expand into Spain, Germany and Italy by end-2026.
Lucis Life has raised $8.5 million in a seed funding round, led by founder Julien Bouteloup. The healthcare and longevity company achieved this milestone just one year after its launch. The funding round signals growing investor confidence in healthcare innovation. Bouteloup, known for his advocacy around addressing challenges beyond financial returns, has positioned Lucis Life as a leading innovator in the longevity sector. Details about participating investors and specific plans for the capital were not disclosed.
Lucis, a French health-tech startup, is entering the predictive health market with backing from Y Combinator and Motier Ventures. The company addresses a gap in Europe's healthcare system, which excels at treatment but falls short on prevention. Founded by CEO Maxime Berthelot, Lucis focuses on making blood tests more accessible and interpretable for comprehensive health monitoring. The startup identifies blood analysis as the best shortcut for understanding overall health status, but notes that access, cost and particularly interpretation remain significant barriers. Lucis joins a growing field of French longevity-focused startups, including Zoi, founded by former Emmanuel Macron adviser Ismaël Emelien, and Kor, which raised several million euros last year. The trend reflects increasing demand for preventive health solutions amongst tech entrepreneurs and consumers.
