Art. 1. Strategic Management Journal 42, no. 2 (February 2021): 233–272.0143-2095https://nrs.harvard.edu/URN-3:HUL.INSTREPOS:37371298Software platforms create value by cultivating an ecosystem of complementary products and services. Existing explanations for how a prospective complementor chooses platforms to join assume the complementor has rich information about the range of available platforms. However, complementors lack this information in many ecosystems, raising the question of how complementors learn about platforms in the first place. We investigate whether attending a temporary gathering—a hackathon—impacts the platform choices of software developers. Through a large-scale quantitative study of 1,302 developers and 167 hackathons, supported by qualitative research, we analyze the multiple channels—sponsorship, social learning, knowledge exchange, and social coordination—through which hackathons serve as a social forum for the diffusion of platform adoption among attendees.en-USStrategy and ManagementBusiness and International ManagementJournal Article2022-04-0510.1002/smj.3230
