Business angels are the second most important source of capital for high-growth ventures. Understanding how business angels make investment decisions is critical for entrepreneurs who want their money. Business angels approach investment opportunities using a boundedly rational approach, where they minimize decision-making effort. They first look at objective venture factors like market size, barriers to entry, and financial viability, then use individual subjective factors to reject opportunities. When assessing risk, business angels examine inherent risk, performance risk, and relationship risk. They also consider the entrepreneur's experience, expertise, and characteristics to assess performance risk, and use behavioral cues to evaluate long-term relationship risk. Business angels also consider the potential exit when making investment decisions.
