*771 in angelList_companyInfo-selfdeclared.txt, see [[AngelList_Database#Parsing_Saved_AngelList_Pages]]. Note that the AngelList data also has angelList_employees.txt and angelList_portfolio.txt as associated files, and that a broader file of candidate incubators, angelList_companyInfo.txt is also available. For self-declaration, we insisted that they called themselves an incubator in either their headline or category, and did not call them self an accelerator, VC, or event. We also excluded virtual incubators and those doing social entrepreneurship. See the Excel spreadsheet for restrictions. AngelList locations were processed into city and state in a separate file. Non-US were then excluded, reducing the count to 733.
