Rewards crowdfunding is a means for individuals or businesses to raise funds for ventures, such as products or projects for new business ventures or a one-time venture. The IS discipline has shown a keen interest in this topic, with more than 100 articles published in the Basket of 8 journals since 2009 related to crowdfunding, with about half of these related specifically to rewards crowdfunding. Much of the research to date surrounds factors or predictors that lead to a successful campaign. However, a close look at the literature shows that a variety of measures is used to indicate success. Our goal is to explore the variety of outcome measures found within the literature and propose some guidelines for their use.
