The entrepreneurial ecosystem is comprised of a wide array of institutions and resources that contribute to the development of entrepreneurship on a local or municipal level. These components have led to the creation of clusters of entrepreneurial success and economic growth, such as Silicon Valley (Palo Alto, California) or Route 128 (Massachusetts).
