Rather than thinking, ‘I’m right.’ I started to ask myself, ‘How do I know I’m right?’”

About The

Ray Dalio

Ray Dalio

In 1975, Ray Dalio founded an investment firm, Bridgewater Associates, out of his two-bedroom apartment in New York City. Over forty years later, Bridgewater has grown into the fifth most important private company in the United States, according to Fortune magazine, and Dalio himself has been named to Time magazine’s list of the 100 most influential people in the world. Along the way, Dalio discovered a set of unique principles that have led to Bridgewater’s exceptionally effective culture, which he describes as “an idea meritocracy that strives to achieve meaningful work and meaningful relationships through radical transparency.” It is these principles, and not anything special about Dalio—who grew up an ordinary kid in a middle-class Long Island neighborhood—that he believes are the reason behind his success.
