BitGeek has made two assertions that have led to much debate:
(1) It is common for successful startups to have single founders.
(2) A structure with a final decisionmaker will work better than a structure where decisions must be made by consensus.
I think (1) depends a lot on how you define cofounder. I'm not interested in extensive discussion about it; I might want to read a summary after it all dies down.
For (2) I am interested in extensive discussion, whether it's statistics, anecdotes, or just supposition. Can people please comment on this posting only with ideas about (2) and leave the word "cofounder" out of it?
