Maxime Berthelot (Lucis): Preventative Health via Blood Testing

The hosts introduce Maxime Berthelot, co-founder and CEO of Lucis, and finish the last Scott Belsky prediction on internal dev teams while he patches in. Maxime explains Lucis' subscription model: full blood panels drawn at partner lab networks like Randox, processed by AI supervised by a five-doctor medical team, producing personalized action plans on nutrition, supplements, sleep and mental health with retests every six months. Fresh off an $8.5M seed led by General Catalyst with YC participation, he argues Europe is three to four years behind the US — where Function Health reached a $2.5B valuation — and credits Bryan Johnson with sparking the preventative-health movement.
