These days the entrepreneurial dream is to build a company that hits one million in revenue without employees or much if any fixed overhead.
Of course the margins will still vary greatly depending on what type of company it is. Does it sell a purely digital products such as apps, software, or educational content? The margins here can be exceptionally high. Does it sell a physical product which must be made first from parts and with labor and then stored somewhere until sold? The margins here can be in line with those of a typical brick and mortar business.
Either way, the one person company that hits one million in sales is the new benchmark.
