are u kidding? favor after favor the CEO asks from the network of each VC partner. Can you do this, can you intro me to that guy, and they can't say, "Well... but you're a zombie"
I mean, yes, obviously, it's rude and unpleasant to say "I don't have time for you because you're not making enough money," but it's a lot more unpleasant to say "I'm firing you and all your employees even though you're making a profit because you keep asking for favors and it's annoying."
Because until they are ready to cut their losses and actually burn this bridge with the entrepreneur, they want to be in a good position if the entrepreneur turns things around and all of a sudden the company is a hit. You don't want to finally get rid of a zombie only to find that if u waited 6 months that zombie would have been a hit.
1) If you cut ties with entrepreneur A cuz you think his company is zombie, his business then folds and he goes on to next thing and doesn't invite you to invest in his new company.
2) If you cut ties with entrepreneur A cuz you think his company is zombie, he doesn't tell you about entrepreneur B who is about to start the next big thing
3) i.e. it's like high school. You want to always be in the right crowd invited to the right parties. And if you stop associating with a certain group of people, you better be sure those are not the future kings.
