Q: What do you call the founder and CEO of a 1-2 person company that failed and went bankrupt? A: Founder and CEO.
Most people would call them unemployed. Calling oneself Founder and CEO doesn't have much, if any, cachet outside of the tech world, since on its own it doesn't mean anything. What matters is what you actually did at the failed company. You know what a plumber in charge of a plumbing company calls himself? A plumber.
It had been a very long day, and after the sixth or seventh group of students that met with me completed their "I'm the CEO, this is the CTO, this is the CMO, this is the COO... on, and this is our engineer" speech I looked at the CEO and accidentally snapped "Well, I guess you've learned an important lesson about how meaningless these titles are."
So I agree with you - the pretentious titles hold very little cachet, and not just outside the tech world, but inside it as well. No one is actually impressed at the zero-experience CEO of his own company until he proves something even in tech.
