Investment thesis
Revent invests in ultra-ambitious founders building generational companies that advance planetary and societal health. It backs teams using defensible, highly scalable technology to drive step-change improvements across three areas: health (products and services transforming how people manage their health and receive care); education and finance (expanding access, lowering cost, and improving effectiveness, as well as making learning and training fit for the digital age); and sustainable consumption and production (helping consumers and businesses make more conscious, sustainable choices).
