Investment thesis
Lionheart Ventures backs exceptional, ethical, growth-oriented founders building transformative technologies with the potential to impact humanity at scale while generating attractive returns. The firm concentrates on two areas: artificial intelligence — favoring technologies that defend and enhance human flourishing, agency, and resilience — and frontier mental health, including psychedelic medicine and neuromodulation that can improve today's standard of care. Composed of former founders who have raised from leading VCs and built companies to exit, the firm emphasizes intellectual honesty, ethical conduct, and counterfactual impact, and aims to help guide responsible stewardship of humanity's most transformative technologies.
