Answer:
Main street
Step-by-step explanation:
"main street" itself is a financial slang, not necessarily a formal term.
Main street buyers are looking for a business who already have proper structure implemented within their operation and already on its way to make it big to the corporate world.
Typically, Main street buyers are the group of people with large amount of capital at their disposal. Buying a business that already have good structures tend to cost higher but possess lower risk of failure.
They do not seek to directly involved in managing the business directly. They will appoint a small group of financial advisers to as delegates so they can focus on other things.
