How young they are? That is a criteria for whether a company should be making money or not? The point of any company really is to make money. These "startups" aren't filing as non-profits right? So they should be making money. If after the first couple months of being open you aren't figuring out how to make money you've done something wrong.
EDIT: Let me edit this to make it more clear. They should be self-sustaining. They should be able to pay their bills and employees. Whether they make a profit or not isn't the point. But if a company doesn't get funding and that alone causes them to disappear then they've done something wrong.
