  The crowdfunding market size has increased exponentially, reaching tens of
billions of dollars and showing the popularity of crowdfunding. However,
according to Kickstarter, 35% backers did not receive rewards on time. To
maintain the trust between creators and backers, and sustain the crowdfunding
business growth, it is crucial to understand how on-time and late reward
delivery projects are different. In this paper, we analyze characteristics of
on-time and late reward delivery projects, especially, focusing on project
descriptions, creator profiles, and activeness and linguistic patterns of
creators and backers. Our analysis reveals that the less complicated a project
is and more actively a creator responds to backers, the higher an on-time
reward delivery probability is. It shows there are significant differences
between on-time and late reward delivery projects.
