Do you believe in the business? It’s virtually impossible for parents to objectively analyze a child’s startup idea. But it’s important to take a critical look at the business concept your child is proposing. What’s the actual size of the market they want to pursue? What are their expected margins, revenues and costs? When do they expect to be profitable? Any professional investor won’t even consider funding an entrepreneur who doesn’t answer these—and many other—questions in a detailed business plan. Parents should insist on the same, and enlist the help of a business savvy friend who can assess the startup idea without the burden of emotion and familial ties.
