How to breed Gazelles is a practical guide on how fast growing businesses can be created. Entering the universe of fast growth requires careful preparation from the early stages of idea generation until the business reaches maturity. Hence, this book follows an entrepreneurial process perspective, commonly described in four stages: (i) opportunity identification and evaluation, (ii) business plan development, (iii) access generation to required resources, and (iv) venture acceleration and management. To address the challenges involved, the book offers a variety of practical tools while, at the same time, it discusses the fundamentals for developing a fast growing activity. Key concepts discussed in this book are: Positive obsession refers to entrepreneurs’ passion, curiosity, persistence, determination and dedication to their business, and ultimately to their customers. The underlying trends of any business require a careful identification and analysis since they have an impact on the daily life of your potential customers, while fast growth is ultimately based upon customer satisfaction. Business model testing, we argue, should take place in the very early stages of a business instead of making lengthy plans before showing a prototype or a proof of concept to customers. Gazelle competencies – among all entrepreneurial competencies – are arguably a precondition for creating a fast growing business, and we assert that these include opportunity recognition, networking, and communication. Risk management is discussed as a tool for strengthening the quality of fast growing business models, with the ambition of continuous improvement. Non-financial resource attraction is arguably of greater importance for Gazelles than funding, since money cannot buy everything, especially not the intangible drivers of collaboration. Yet, fast growth is the result of a joint, collaborative effort. This book could be helpful to anyone with fast growing business ambitions, i.e. a student, a scientist, an entrepreneur, or a manager in an established company. Good luck, and enjoy breeding your Gazelle!
