The Kauffman Foundation has just released the first examinations of Inc. 500 companies over the 30 years Inc. has been compiling the list. Some of the results were surprising, not least of which was the dominance of the South over other regions in founder preference. Not typically considered to have great entrepreneurial ecosystems, the South as a region outperformed the others in nearly every category included founders educated, retained, most companies founded there, and highest net flow of founders.
Below we can see the movements of founders who started their companies in the five Southern cities with the most Inc. 500 companies in our data. 267 companies were founded—the top five cities in the Northeast, West and Midwest boast only 199, 220 and 106 companies respectively.
