"Founder" title drama is mostly around successful companies in my experience. Basically some additional mojo can be had a funding discussions if you can legitimately claim to be a 'founder' of some previous success (the bigger the better). Especially in social settings it is strange (and to my twisted humor funny) when people will say they 'worked' at one company and 'founded' another company when they had the exact same role in each company at the same level of development and differ only in the perception of 'success' or 'not success'.

After reading the article on how primates use 'fame' in dominance games that made the rounds here I found that it identified that sort of behavior pretty precisely.
