About
Adam Gries is Managing Director at Authentic and an angel investor whose primary focus is aging and longevity, an interest he has held since encountering the idea of Longevity Escape Velocity in 2007. A self-taught software engineer and operational, product-focused CEO, he founded and sold four companies that collectively reached more than 80 million users, and he studied neuroscience in college, including MRI-based research at Massachusetts General Hospital. Alongside his longevity work, he invests opportunistically and is drawn to the intersection of behavior and technology.
