Entrepreneurship is changing. Technology and social networks create a smaller world, but widen the opportunity horizon. Today’s entrepreneurs build organisations and create value in entirely new ways and with entirely new tools. Rather than just exploit new ideas, innovative entrepreneurs design organisations to make sense of unlikely opportunities. The time has come to overhaul what we know about entrepreneurship and business models. Models of Opportunity links scholarly research on business models and organisational design to the reality of building entrepreneurial firms. It provides actionable advice based on a deeper understanding of how business models function and change. The six insights extend corporate strategy and entrepreneurship in a completely new direction. Case studies of innovative companies across industries demonstrate how visionary entrepreneurs achieve unexpected results. The insights, tools and cases, provide a fresh perspective on emerging trends in entrepreneurship, organisational change and high-growth firms.
