Investment thesis
Lionheart Ventures backs exceptional, ethical, growth-oriented founders building transformative technologies capable of impacting humanity at scale while delivering strong returns. The firm concentrates on two areas: artificial intelligence that defends and enhances human flourishing, agency, and resilience during a transition it views as more disruptive than the Industrial Revolution; and frontier mental health technologies such as psychedelic medicine and neuromodulation aimed at improving standards of care amid a global mental health crisis. As former founders themselves, the team draws on firsthand company-building experience and a network of expert advisors, prioritizing intellectual honesty, ethical conduct, and counterfactual impact in responsibly stewarding humanity's most powerful technologies.
