"A few years ago, a date brought Nick Gray to the Metropolitan Museum of Art and showed him all of the pieces she really loved. Something clicked. “The passion was contagious,” Nick said. “I went back to the museum dozens of times, iPad in hand, doing a deep dive into the pieces I found most interesting.” As this became a serious hobby, Nick, who has no background in art or history, began inviting friends to join him at the Met to teach them fun facts about lesser-known works of art and artifacts. What started as a new obsession with museums, grew into Museum Hack, a million-dollar company that leads “renegade” small-group tours of museums in New York City and four other cities."
