While many sharing economy startups are found, a majority of them go unnoticed and fail to reach a critical mass for survival. Prior studies have mostly focused on consumer engagement as success factors for sharing economy businesses. Yet, there is a scarcity of research on success factors at the entry level of sharing economy businesses, namely, the fundraising rounds. This study uses a Necessary Condition Analysis (NCA) on 99 sharing economy startups to explore how human capital, innovativeness, and entrepreneurial footprint impact their fundraising success. Our findings show a large necessary effect for human capital and entrepreneurial footprint, and a medium effect for innovativeness on fundraising success. Additionally, firms only need a range of 30% to 40% level of three factors to achieve at least 40% level of fundraising success.9 pagesengAttribution-NonCommercial-NoDerivatives 4.0 InternationalCrowd-based Platformsentrepreneurial footprintinnovativenessnecessary condition analysissharing economy startupsocial capitaltext10.24251/HICSS.2022.542
