This book offers a novel perspective on starting-up new business ventures through examining the process by which they become part of the existing business environment. The book highlights the importance of inter-organizational business relationships. Asserting that new ventures need to interact and connect with customers and suppliers, alongside policy actors and universities, Starting up in Business Networks demonstrates how beginning a new venture demands initiating and developing business relationships. Noting a lack of prior research into the process by which start-ups embed into an existing business network, this book presents examples from countries such as Sweden, Italy, the Netherlands and China to analyse the emergence and evolution of start-up business networks.
