The San Jose Redevelopment Agency (RDA) fostered and continues to nurture incubators. In partnership with the RDA, San Jose State University (SJSU), through its Foundation, operates four fairly autonomous loosely coupled university based incubators (UBIs). Their primary mission is to develop start-ups. They also provide excellent learning opportunities for students. What they have not done is commercialize university or faculty intellectual property. The incubator directors are experienced business people who have the business acumen to nurture start-ups successfully, which they have done. The RDA, SJSU, the UBIs, and the incubator directors are all part of the entrepreneurial system that characterizes Silicon Valley.
