Lucis runs a European subscription service for preventive health, using regular blood tests to give people personalized insights aimed at extending their healthspan. The product relies on blood draws at 400+ partner labs and analyzes 180+ biomarkers, with AI interpretation reviewed by a medical team, presented through a dynamic dashboard and a prioritized, five-pillar action plan (nutrition, supplements, physical activity, sleep, mental health). It differentiates itself by combining data-driven AI analysis with medical expertise and longitudinal health tracking, rather than providing static reports, all within a European lab and physician network under a subscription model. The goal is to help individuals prevent chronic diseases and take proactive steps to improve long-term health.

Simplify's Take
What believers are saying
- Lucis reported 10,000 users and 1,000,000 analyses by July 2026.
- Seventy-five percent of six-month follow-ups improved three biomarkers without medication.
- Expansion into Spain, Germany, and Italy by end-2026 extends the addressable market sharply.
What critics are saying
- Thriva, Function Health, ZOE, and Neko Health crowd the same preventive-testing market.
- Regulatory scrutiny on health data and clinical claims can force costly redesigns in 2026.
- If repeat testing stays premium, Lucis becomes a one-off lab intermediary, not an endurance company.
What makes Lucis unique
- Lucis pairs 110+ biomarkers with physician-reviewed AI and longitudinal tracking.
- June 2026 Series A from Singular, General Catalyst, and Y Combinator validates category momentum.
- Partner labs with Eurofins and Randox create European distribution without owning clinics.

↑ 25%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.
