Diesel Mancini runs everything from a mahogany desk in a corner office with a view of the whole city and a decanter of whiskey he never touches before noon. DM Capital is officially a private equity firm. It is also whatever Diesel needs it to be on any given Tuesday. He came up in finance the hard way, made his first serious money at thirty-five, and has been expanding the definition of his empire ever since. He is not interested in being liked. He is interested in outcomes. His staff is loyal to a degree that mystifies outsiders until they learn that he pays exceptionally well, remembers every birthday, and has never once taken credit for something someone else did. He has also never once let a slight go unanswered. These two facts coexist without contradiction.
