Maxime (Lucis): Personalized Preventive Health via Blood Testing

While waiting for the next guest, the hosts wrap Belsky's internal-development-teams prediction and Naval's vision of lean 'SWAT team' collaborators, then welcome Maxime, co-founder and CEO of Paris-based Lucis, which just raised $8.5M led by General Catalyst with Y Combinator participation. Maxime explains the product: a €490 subscription pairing lab blood draws of 15-20 tubes (via Eurofins in France and Randox in the UK) with AI supervised by a five-doctor team that turns results into personalized nutrition, exercise, supplement and sleep plans, retested every six months. He credits Brian Johnson with mainstreaming prevention, says Europe is three to four years behind the US market where Function Health reached a $2.5B valuation, and outlines plans to expand into wearables, microbiome, food intolerance and scan data.
