Formerly Zero Health, focus on proactive healthcare, prioritizing prevention rather than reactive care, with a system that emphasizes maintaining health MoreLess
Lucis is a Paris preventive-health platform (formerly Zero Health) that turns regular blood testing into AI-supported, clinician-reviewed action plans spanning nutrition, supplements, activity, sleep and mental health. Members draw blood at partner labs across Europe; the service analyses a large biomarker panel and delivers a longitudinal dashboard rather than a one-off PDF, positioning itself as prevention and education rather than diagnosis. After an $8.5 million seed led by General Catalyst with Y Combinator and Kima Ventures, Lucis raised a $20 million Series A (about €17–€17.3 million) in May 2026 led by Singular, with General Catalyst and Y Combinator returning, bringing total funding to roughly $28 million to expand markets, lab/physician networks and the AI platform.
