The title is click-bait, the episode is a conversation about building a bootstrapped quiz business and (imho) interesting thoughts on life and memory by one of the founders.
If you are into bootstrapping the whole Indie Hackers podcast is worth checking out. Don't let the titles distract you.
If you listen to the episode , the founder says in the beginning he was just creating the questions and 'grading' them individually. That seems pretty 'simple' from a business process standpoint.
