Drop some stories about what happens to founders and founding teams when startups aren't successful [I will not promote]

Recently I've been considering starting up or joining an early stage startup as a founding engineer. While the positive anecdotes are well known, like cashing out millions and then going on to startup even bigger companies, I'd love to hear tales from places where things didn't work out. What did the founders and the founding team members do after shutting shop? Is it hard to find roles after that or do you have to settle for relatively junior or lower paying roles?
