Jamba Juice started out in San Luis Obispo, CA in 1990 as a little juice shop with a big idea: that eating better should be easy. For nearly 30 years, Jamba Juice has led the way in creating and defining the smoothie and juice category as we know it. As of 2020, Jamba has more than 850 locations operating in 36 U.S. states, as well as the Philippines, Taiwan, South Korea, Thailand and Japan.
