About The

Ray Dalio

Ray Dalio

In 1975, Ray Dalio founded Bridgewater Associates, out of his two-bedroom apartment in New York City. Over forty years later, Bridgewater has grown into the largest hedge fund in the world and 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 unique principles that have led to his and Bridgewater’s unique success. It is these principles, and not anything special about Dalio, that he believes are the reason behind whatever success he has had. He is now at a stage in his life that he wants to pass them along to others to do whatever they think is appropriate to do with them.
