Why would you want to cash out out of something you love?
These kind of businesses struggle.
But when you have a rich parents, they you come up with some start up idea, hire a team of people to make it - then yes cashing out is a win. But those people don't look at it as business, as a real thing that adds value for other people, but pure selfishly as showing themselves they can pull this off.
These people also often steal ideas from people who care and love what they do. Often those people become wage slaves in those rich daddy companies.
