Digital ventures are entrepreneurial young firms that introduce new digital artifacts that are “ever-incomplete” and “perpetually-in-the-making” onto the market. The study examines how six digital ventures continued to develop their digital market offerings post launch. Three key designing mechanisms are identified that explain continuous post-launch product development in digital ventures: deploying complementary digital objects, architectural amplification, and porting. The study discusses how these mechanisms advance our understanding of how digital technologies change entrepreneurial processes and outcomes.
