Lionheart Ventures is a venture capital fund that invests in both artificial intelligence and mental health, based on the belief that better thinking, personal agency, and collective decision-making are connected parts of the same larger challenge; its advisors include experts in AI safety as well as leaders in psychedelic medicine and regulation, and its founder combines a background in successful startups with years of practicing meditation and yoga. Despite this unusual mix of futuristic technology and inner well-being, the fund has backed real commercial successes, including two companies, Calm and Goodfire, that have grown into unicorns.
