A substantial number of entrepreneurial firms operate in industries and markets where network effects dominate, and a substantial proportion of the total value created is created through the number of customers of a particular service or product. This article explores entrepreneurship in digital network markets from the view of value creation and value appropriation, exploring how network effects can become additional sources of value creation and how sustainable competitive advantages can be created in entrepreneurial firms through mechanisms such as technological lock-in. Taken these into consideration, we suggest further work is required so that entrepreneurs can enhance the sustainable competitive advantages in the industries they operate in. We also offer suggestions for future research in the domain of digital technologies in the entrepreneurship domain.
