Origin Story

Founded in 2019 by David Langer, a St Anne’s College, Oxford alumnus and experienced entrepreneur, Lionheart Ventures emerged from a conviction that the most pressing challenges of our time—ranging from AI-driven disruption to the global mental health crisis—require proactive, visionary investment. The firm’s leadership team includes seasoned investors and former founders, such as Brandon Goldman and Ben Lee, who bring firsthand experience in scaling startups and navigating complex technological landscapes. Over time, Lionheart has sharpened its focus, narrowing its investment thesis to AI and mental health technologies, and building a network of expert advisors in AI safety, psychedelics, and neuromodulation. This evolution reflects a deliberate strategy to maximize impact in domains where technological breakthroughs can meaningfully reduce existential risk.
