Lucis, a French startup
focused on expanding access to preventive health testing, has closed an $8.5
million seed round led by General Catalyst, with participation from Y
Combinator, Kima Ventures, Motier Ventures, Circle.Co, and North South
Ventures.
Founded by Maxime Berthelot, Baptiste Debever, and Max Guerois, Lucis offers a platform that
translates blood test results into a set of indicators tracked every six to 12
months. It provides a structured view of more than 180 biomarkers, covering
areas such as cardiometabolic health, hormones, inflammation, liver and kidney
function, and selected micronutrients, with the aim of helping users identify
potential imbalances and early signals associated with chronic disease.
The company positions
Lucis as a preventive tool to support understanding and monitoring of health,
and notes that it does not replace medical consultation, diagnosis, or
prescribing.
Our mission is to empower
individuals to take ownership of their health by giving them a clear view of
key indicators before symptoms even appear, and providing practical guidance to
improve their well-being, without replacing physicians,
said Maxime Berthelot,
CEO and co-founder of Lucis.
Members complete check-ups
through certified medical biology laboratories across Europe. Results are
reviewed by a multidisciplinary medical team, with AI used to help surface key
signals and track changes over time.
Instead of receiving a
static report, users access a dashboard and a prioritised action plan organised
around five areas: nutrition, supplements, physical activity, sleep and
recovery, and mental health. Lucis positions this model as an extension of broader
consumer health tracking, adding biological markers and clinical oversight to
support a more structured, public health–aligned approach.
The new funding will be
used to accelerate rollout in France, the UK, Ireland, and Portugal and into
additional markets, expand its network of partner laboratories and clinicians,
and further develop its AI-enabled preventive analysis and support platform.
