What are some alternate sources of financing apart from borrowing loans?
For companies, the obvious other choice is providing equity. You can give up part of the ownership of your company for some money in return. However, for personal financing, you can not give up ownership of yourself (at least I hope not), so this is not an option.
The only other option that I can think of is through raising money. Websites such as GoFundMe and Crowdrise can be effective for raising money for good causes, such as if you have a hospital bill you need to pay off. However, if you are just trying to borrow money for no specific reason, it is hard to do it in any other way than through loans. Even when you purchase with a credit card, you are still technically taking a loan from the credit issuer, and when you borrow from friends and family, it is still a loan.
Overall, companies finance through equity and debt, whereas individuals can practically only finance through borrowing loans.
