Startups often depend on investors to get their businesses off the ground. In the later stages of building a company, entrepreneurs may rely on private equity. However, early in the process of starting a company, angel investors are often the best option for funding. Besides providing capital, they can offer connections and guidance. An angel investor typically has significant knowledge and experience within the industry they invest in.
