When you don't invest in your new and smaller businesses, it is called debt investment.
Debt investment basically means opting to use an amount borrowed to finance one's business (either big or small business). This investment refers to a scenario when an investor (i.e. banks) lend money to the entrepreneur with the expectation that the entrepreneur will pay-back the investment with interest.
This type of business running system is somewhat burdensome because of repayment of the loan with interest.
The advantage of this method of financing is that the capital is fully provided to the business owner.
