Sweetgreen co-founder Nicolas Jammet dives into how the brand got started, what setbacks it faced and how it's using automation in its 250-plus locations. Not just any restaurant — Sweetgreen, the mega-popular, fast-casual chain with more than 250 locations, a public stock listing and — for a brief but unforgettable stretch — its own music festival featuring Kendrick Lamar and The Weeknd. Jammet co-founded Sweetgreen in 2007 with friends Jonathan Neman and Nathaniel Ru. Today, Jammet is the company's chief concept officer, Neman is CEO and Ru is chief brand officer. Now, the files are backed up, and Sweetgreen is doing what it's always done best: seeing where food is going, and quietly getting there first.
