According to a 2003 report by the National Business Incubation Association (NBIA), these businesses are usually "grown your own" technology-orientated startup firms. They are usually one of three types: (1) information technology and electronics firms; (2) those engaged in biotechnology and biomedical applications; and (3) enterprises carrying a mixture of technology concentrations.

Technology business incubators tend to thrive in places having the following resources:
•Access to research universities, federal laboratories, and corporate R & D facilities;
•Entrepreneur-oriented scientists and engineers;
•A cadre of business and legal professionals such as accountants and lawyers;
•Availability of public and private capital resources (such as debt and equity investment);
•An existing pool of technology companies and professionals that can mentor and advise startup firms.
