Answer to Question 1
Financing with a loan involves accepting an obligation to repay a debt. Financing with venture capital involves accepting funds in exchange for a portion of ownership of the company. With a loan a business owner retains control of her company but must generate enough profit to cover operating costs and loan payments. This may not be possible for a new company. With venture capital there is no obligation to repay the funds. However, a business owner must forfeit some profits and control of her company to the venture capitalist.
