The Mayfield Fellows Program is a university program that offers students in-depth training and experience in high-tech entrepreneurship. The program, originally called the "Technology Ventures Co-op" was founded in 1996 at Stanford University and expanded in 2001 to include the University of California, Berkeley. The two programs each have a slightly different focus. At Stanford, the students are juniors, senior, and co-terminal masters students, primarily in engineering and science. At Berkeley, the students are generally graduate students in business or engineering.
