BILLION  SELF-MADE SCORE: # SOURCE: IN-N-OUT BURGER AGE: 37 RESIDENCE: GLENDORA, CA PHILANTHROPY SCORE: At 17, Snyder started working at her family’s In-N-Out Burger, separating lettuce leaves and operating the register at a location in Redding, California. Not long after, her father died and she became the chain’s sole heiress. Over the next decade she received stakes in the company as part of a complex trust created by her grandparents. She got the last piece when she turned 35 in 2017 and today owns about 97%. As company president, she has overseen careful expansion to Texas and Oregon followed by Colorado next year.
