The chapter investigates what are the key drivers for emergence of an entrepreneurial ecosystem (EE), and how those operate. To answer those questions the chapter utilizes a single case study design. The empirical context is a historical high-tech EE in Norway that emerged organically from a university. The study finds engaged individuals to be the key drivers for EE emergence. In EE evolving from university the key drivers are both professors and students. They operate as brokers of information between university and business worlds, entrepreneurial and scientific role models, and inspiration for commercialization of technology. The study calls for greater attention in investigating the driving forces behind various types of EEs.

Previous studies of business angels have shown that the population is very heterogeneous, with various studies developing typologies to describe different categories of investor. This chapter provides a critical review of previous research on business angel categorisations to highlight the key contributions. The authors note that previous studies have categorised business angels using a wide range of variables, mostly grouping investors according to investors’ characteristics and often derived from data rather than theory. The main contribution of these studies has been to develop a more sophisticated and nuanced view of the definition and behaviour of business angels – which breaks free from an oversimplified stereotypical view of business angels. However, in many cases the categorisations are fragmented, lacking a theoretical anchor, supply-side driven and rather static. The authors conclude that these studies have not significantly influenced policymakers and policies to target different categories of business angel.
