Los Angeles has always been an incubator for innovative business ideas. The Los Angeles Business Journal’s Innovation Special Report takes a look at 20 companies across many industries that are developing new technologies and business practices to solve problems and simplify processes — from diagnosing brain injuries using noninvasive methods to moving people from point A to point B at 200 miles per hour. These companies are looking to build better batteries and robots that cook. They are putting office access in the palm of employees’ hands and are finding practical business applications for virtual reality technology. These companies’ capabilities to create new ideas and products are one of the remarkable aspects of L.A.’s business community.
