Part of me thinks this person's job is complete.

He started an idea, developed, and has a team to continue it.

He did his role.

What is next for him? Hopefully he has enough money to live without working. Then he can put his efforts into himself.

Well there's no way he gave up his entire stake in the company. I would assume he continues on as part of the board, or at least an advisory role.
