The PowerBar company was founded by Brian Maxwell, a Canadian athlete and entrepreneur and Mike McCollum, in his kitchen with Maxwell's girlfriend, Jennifer Biddulph, a nutritionist who later became his wife. They used $55,000 in cash to launch the company in 1986 in Berkeley, California. This was the first "energy bar" for use by endurance athletes, such as ultra marathoners, jiu jitsu practitioners and cyclists, while competing. He eventually acquired a headquarters building in downtown Berkeley.
The company eventually earned $150 million in sales before being purchased by Nestlé in 2000 for $375 million.
In February 2007, PowerBar moved its headquarters from Berkeley, CA to the Nestlé headquarters in Glendale, CA. With the move came the hiring of an entirely new marketing team.
