Why do some people start a company, he must bring a name in, and the funds are all his own? Why?

Hello! This involves a one-man company or a partnership company. Because of convention, people think that a one-man company has no strength, and its ability to resist risks is small, which gives people a bad feeling. In the case of a partnership company, a person in charge can be added instead of a one-person company to take responsibility, and the ability to resist risks is significantly improved.
