Cofounder, The Kitchen
What he’s known for
In the 1990s, Musk sold a tech startup that he cofounded with his brother, Elon, for more than $300 million. Now a restaurateur, he uses his eateries—the Kitchen, Next Door, and Hedge Row—to promote healthy food. The restaurants also help support his philanthropic work building educational gardens for schools.
Next Door, Musk’s casualdining concept, is expanding rapidly. There are now seven locations—in Colorado, Indiana, and Tennessee—with plans to add another 50 by 2020.
