In 1993, the company opened and started along with two other California stores owners, one in Palo Alto and one in Irvine. The original San Luis Obispo Juice Club was located at the corner of Chorro St. and Foothill Blvd. and still exists as a Jamba Juice location.
Juice Club Inc. of San Francisco changed its store name to Jamba Juice in 1995. Said founder Perron:
“ I'm surprised there aren't more companies creating a culture beyond selling, [offering] a soulful experience for the customer. That's been the basis for our success. ”
In August 1997, Jamba entered into an operating agreement with Whole Foods Market to sell only "natural" products inside some of the Whole Foods's locations, including Jamba's smoothies' ingredients. For this reason, offerings at Whole Foods sites may differ from those at stand-alone sites. Dianne Yzavel is the founder of Zuka Juice. Jamba Juice acquired all nation-wide Zuka Juice, Inc. stores in March 1999. Zuka Juice was founded in Orem, Utah, and also was a prominent smoothie company at the time. Since then Jamba Juice has expanded to become one of the nation's best known smoothie chains, emphasizing the benefits of a healthy lifestyle.
