When you start a company, you and your founders own 100% of the company. That is usually in the form of founders stock. If you never raise any outside capital and you never give any stock away to employees or others, then you can keep all of that equity for yourself. It happens a lot in small businesses. But in high growth tech companies like the kind I work with, it is very rare to see the founders keep 100% of the business.
