Crowdfunding is a very current, and popular topic. It is especially in young start-up companies an effective method for procuring funds while serving at the same time as a powerful marketing tool with the ability to help gauge prospective market potential. Both the growing number of campaigns and increasing amount of funds raised, show the popularity of crowdfunding. Investors, the government, media and businesses should be paying attention to this phenomenon. Especially in the academic circles, crowdfunding received a lot of attention recently. There has been extensive research on the topic of crowdfunding, resulting in a growing number of books and articles published. However, there are still areas which have not been fully addressed. One of which concerns the relationship between the business model of a company and its success in a crowdfunding campaign. What aspects of a business model are relevant for the outcome of a campaign? In this Masters thesis, this question is answered and thereby a contribution to the academic debate shall be made. This will serve the purpose of helping those people and organisations involved in future campaigns, investors, businesses and platforms, to be more resourceful, because unsuccessful campaigns have the potential to be costly and time consuming. In this study, finished campaigns of start-up companies located in Austria have been identified and later analysed, using methods of descriptive statistics. Positive, negative and neutral influences of the business model of each company on the success of their campaign, were identified. Studies from abroad, in particular those dealing with the success factors of campaign design, presentation and legal aspects are also examined. The validity of these, in particular with regard to Austrian start-up companies, was tested. Finally, an overview of the market for crowdfunding for Austrian start-up companies is presented.
