Jonathan Neman is a co-founder and co-CEO of Sweetgreen, a hip, farm-to-table style salad chain. Mr. Neman, along with Nicolas Jammet and Nathaniel Ru, opened the company’s first location in Washington D.C. in 2007, the same year they graduated from Georgetown University. Now, nine years later, the fast-food salad lunch option is nationwide. There are now 43 locations—and more opening every week. As of last summer, Sweetgreen raised a total of $95 million in venture funding. At the beginning of the year, the company moved its corporate headquarters from D.C. to Los Angeles, the better to fuel its westward expansion.
