Angel investors are high-net-worth individuals who invest their own money in startups, often with the goal of achieving higher returns than public stocks or bonds. They seek rapid growth, strong leadership teams, early results, long-term strategy, risk analysis, and a clear plan for using the investment. Accredited investors have a higher net worth or income threshold, but not all angel investors are accredited. Working with angel investors offers benefits such as no repayment expectations, willingness to take risks, and guidance from experienced entrepreneurs. However, founders must exchange equity and consider the limitations of angel funding. To secure funding, founders need a persuasive business plan, functional prototype, and a clear understanding of their vision and strategy.
