My first real job was at a startup that was at one time a one man show (though it grew and shrank over time). The founder was an ego maniac and a micro-manager who had big visions of financial success but no clue on how to achieve it. I heard a lot of stories of an endless parade of previous employees (which should have been a major red flag) and while I was there for only about 2 years the company cycled through people.
