Stephanie had decided to use her Masters project to build upon the research she had undertaken as part of her undergraduate studies. During this she had researched Business Angels, private, wealthy individuals who invested large amounts (between £10 000 and £500 000) of their own money in small, young businesses, with which they have no family connection (Deakins and Freel 2003). For her Masters dissertation she wished to develop this research to answer the research question: ‘To what extent and why do Business Angels become involved post investment in the companies in which they have invested?’ She had decided to collect data to answer this by administering a questionnaire to Business Angels throughout the United Kingdom (UK).
