A decade ago, billionaire entrepreneurs Peter Thiel and Elon Musk decided to take booming start-up PayPal public from a small coffee shop along Palo Alto's University Avenue. The street, the epicenter of Silicon Valley high tech, also helped incubate such now-established giants as Facebook and Google. But today, Thiel has seemingly left the Valley behind.
The venture capital funds he runs are based 30 miles north, in a San Francisco building with views of the Golden Gate Bridge. A number of highly publicized start-ups like Twitter, Square, and Pinterest are also located in the heart of urban San Francisco. As Twitter co-founder Jack Dorsey tweeted last February from his new headquarters in San Francisco’s Mid-Market neighborhood, "I love the idea of an urban corporate campus with all the energy and variety that provides."
