I think fighting between cofounders is probably more of a symptom that is highly correlated with failure than a cause.

Chatting with a friend the other day, I was musing at how Network Appliance is a very generic name for what is basically a giant network drive. A better name might be Network Disk, Appliance doesn't really tell you what it is. I proposed they could go whole-hog and change the name of the company to "Electrical Object". Then, coming up with one of my usual stupid analogies, I reasoned:

"It would be like going into a VC's office and telling them your business plan is: Engage in activities such that the quantity of money received exceeds the quantity transmitted."

And with that, I was enlightened.

That is far better than 95% of what VC's actually do fund.
