Little is known about innovative and successful enterprises in the countries that, until 1990, were part of the Soviet Union. Most previous research has extensively covered barriers to entrepreneurship and innovation that exist in these countries, some of which undoubtedly represent a hostile and harsh environment for any entrepreneurial activity. In this book, a different perspective is introduced. The focus is shifted to the innovative potential that these environments provide, demonstrating how entrepreneurs have been able to convert possibilities in hostile business environments into successful businesses. Through this collection of six in-depth case studies, the authors illustrate how successful and innovative businesses were able to develop in countries such as Russia, Belarus, Kazakhstan, Kyrgyztan, Moldova and Ukraine. Each case study presents an overview of the country’s key economic indicators and the role of small and medium-sized enterprises (SMEs) in the economy, followed by the presentation of a case study of a successful SME.
