NICOLAS JAMMET

Cofounder and CO-CEO, Sweetgreen

What he’s known for

Jammet and his cofounders, Nathaniel Ru and Jonathan Neman, launched Sweetgreen soon after graduating from Georgetown in 2007. With Jammet in charge of food operations, the fast-casual salad chain has grown to more than 80 locations in eight markets.

Latest move

Sweetgreen is bolstering its digital capacity: It went fully cashless last year in nearly all of its restaurants and has been taking more orders through its app, which allows customers to sync calorie counts with Apple Health.
