If someone wants to know your business, tell them to invest in it.

The line frames curiosity about a venture as something that should be matched by commitment. It suggests that detailed access to a business—its plans, finances, or strategy—has value, and that those seeking such information should share risk by investing rather than merely asking questions. In that sense, it functions as a boundary-setting maxim for entrepreneurs: support is welcome, but probing interest without “skin in the game” can be a drain on time or a potential competitive threat. The quote also implies a moral economy of reciprocity: genuine interest is demonstrated through tangible backing, not just inquiry.
