TRAVIS KALANICK

$3.5

BILLION  SELF-MADE SCORE: * SOURCE: UBER AGE: 43 RESIDENCE: LOS ANGELES PHILANTHROPY SCORE: The former Uber CEO watched from the sidelines as the company went public in May. Kalanick’s net worth is down $2.4 billion since last year, partly because he put about $1 billion of his Uber shares into a charitable remainder trust and in part because of Uber’s poor stock performance. He remains on Uber’s board and is also CEO of City Storage Systems, which is working to create virtual restaurants. In August he reportedly purchased a $36.5 million penthouse in New York City.
