About Lucis
Summary
Lucis builds a preventive health membership for European consumers who want to go beyond standard blood panels. Members get twice-yearly lab tests covering 110+ biomarkers across 11 body systems, combined with wearable data and a health questionnaire, then receive personalised recommendations on what to change. The product replaces the fragmented loop of generic GP blood tests and self-interpreted results with a single, ongoing health companion.
Business model
Recurring membership fee per person, with access to a network of 450+ partner labs across Europe.
Go-to-market
Consumers sign up directly through the Lucis website and walk into a partner lab for testing, making it fully self-serve from signup through results.
