In 2013, Hillary Lewis came up with the idea for her Charlottesville-based organic juice company, Lumi Juice, after shopping at a Whole Foods store. Today her products are found at about 350 stores in the U.S., including Whole Foods and Fresh Market. Lewis was a student at the University of Virginia’s Darden School of Business when she developed the concept for Lumi. At Whole Foods, she picked up a juice made with high-pressure processing and became curious about that production method.
