This chapter elaborates the premise that technology cannot be disembedded from human action. Assuming that new organizations can appear from different populations, such as industries, universities, other various kinds of populations, we specify how different natures of technology result in the creation of different kinds of organizations. In particular, we conceptualize technological embeddedness, based on a perspective of community ecology. And based on the concept, we figure out that the nature of technology, at the population level, can be classified into four categories: local specialism, generalized specialism, specialized generalism, and global generalism. With this classification, this chapter illustrates how different organizations can be formed according to different natures of technology. And we discuss how this differentiated formation of new organizations driven by different natures of technology is understood in terms of techno-entrepreneurial ecosystems.
