Narratives are a vehicle for assembling details about ideas and a structure for communicating them to a wider audience. In this study, I examine narrative honesty and the extent to which they convey credible claims for acquiring financial support. I argue claims with quantifiable details that make distinctions are beneficial, but that potential backers penalize overly complex and speculative claims. I test this argument by analyzing a sample of crowdfunding campaign texts and find supporting evidence for my predictions. These results advance the literature on entrepreneurial narratives and establish some baseline characteristics of donation- and rewardbased crowdfunding sites.
