What city is the entrepreneurship capital of the United States? Where does one find the densest enclave of concentrated, up-and-coming startup culture? Silicon Valley? Palo Alto?
​
Nope. It's Boulder, which boasts twice as many startups per capita versus any other American city; this pole position has been a long time in the making: "Since 1960, it has quietly nurtured nascent industries, including natural foods, computer storage, biotech, and now Internet companies." While Boulder is famed for its emphasis on work/life balance, make no mistake; its citizens take the 'work' part of that equation seriously.
