Lucis

Lucis is a preventive health platform. Members fill in a health questionnaire, connect wearables, and give blood, urine and saliva samples at partner labs twice a year. Results are shown across 11 body systems in a private dashboard, together with a personalised action plan covering nutrition, sleep, activity and other areas.

Customers are adults aged 18 and older who buy an annual membership, priced at €490 per year on the website, with optional add-on tests. The company states that it is not a medical platform and does not replace diagnosis or prescriptions. The website cites 10,000+ members, 450+ partner labs in Europe, and HDS-certified hosting with ISO 27001 and GDPR compliance.

Lucis is based in Paris and was founded by Baptiste and Max, according to its careers page. The company says it is backed by Y Combinator (X25) and other investors, and that it is live in four countries. Its open roles cover engineering, clinical, customer care and general and administrative functions, with listings in Paris, Barcelona and London.
