Calley Means is the cofounder of True Medicine, built around the idea that food (and lifestyle habits like exercise and sleep) is medicine. The company’s goal is to make tax-advantaged spending on healthy food and exercise seamless.

He is writing a book, co-authored with his sister Dr. Casey Means, about how preventable cellular dysfunction (caused primarily by food) is at the root of nearly every chronic condition that plagues American life—and how to fix it.

Calley has invested in healthcare companies aiming to transform the current sick-care system, including Levels (providing patients with more metabolic health data), Atai (a leading mental health/psychedelic company), Delix (a leading psychedelic company), and Rejuveron (a leading longevity company), as well as consumer startups such as RapidSOS, UpSmith, Dynamic.xyz, and Vibe. Previously, Calley co-founded a company called Anomalie with his wife, which was acquired by David's Bridal.

Passionate about public policy, he graduated from Stanford and Harvard Business School and started his career in politics. Today, he is active in groups such as Council on Foreign Relations, Teneo, and Stand Together.
