I've seen quite a few of these funded entrepreneur-lifestyle kids now; I've worked (briefly) with many of their companies. Many of them are making enough of a real go at it such that I can't tell them from others, but quite a few don't know enough about how a default alive business works and deliver a DoA even when the core idea or a short pivot works and has traction - these guys need so much better PMF to succeed.

The best businesses I've seen parents find for their children are lettings agents (urgh) and basic manufacturing (last mile door assembly etc.). You can get the business model in a six month course, the staff are minimum wage, the product is high margin. If your parents buy the building you are so close to default alive its a joke. Grow the business, flip it, and try the big idea.
