Book excerpt: This book analyzes the communication and writing strategies necessary to craft and maintain ongoing crowdfunding campaigns to support businesses, nonprofits, artists, and others. Drawing on theory from technical communication and user experience, as well as mixed methods research, and text mining, this book takes an evidence-based approach to understanding the successes and failures of crowdfunding campaigns. It examines campaigns across a range of platforms, including Kickstarter, GoFundMe, IndieGoGo, and Patreon. The book breaks down successful exemplar campaigns that have proven long-term success to show what has worked and why, giving readers a solid foundation to research and create a campaign of their own. Sustainable Crowdfunding serves as a supplemental text for courses in technical and professional communication, user experience, communication research methods, and digital marketing, and will be of interest to both communication scholars and advanced crowdfunding professionals.
