San Francisco, 156 companies

The Bay Area is all about emerging tech companies, and it's the place to be if you're in search of funding. Top VC firms like Andreessen Horowitz, Sequoia Capital, and Accel Partners fuel the area, as do many angel and early-round investors. Accel backs San Francisco list-topper AdRoll, for instance. Stanford also produces engineers, many of whom create companies in the area, and earn a two-year city payroll tax credit in the process (Twitter did this recently). Still, the Bay Area does not top the list of the cities with the most Inc. 5000 companies.
