1.) Have you admitted to your cofounder you screwed up? You're owning up to it here (+1) but to him?
2.) Did you just screw up your CEO part of the job or both CEO & CTO?
3.) Could you live with just being a code monkey (role player) for a while?
4.) How many people are in the company?
2) That one's a bit difficult to judge, I certainly screwed up the management parts of my job, whether I'm any good as an architecture designer and someone who makes technical decisions ... can't really tell; I think I managed quite alright.
3) I guess potentially I could, but not very happily. I'd rather remain a CTO and have some very hands-on/tough coaching regime to get me into shape within a few months.
4) Right now there's just the two of us, but some other people are involved on a looser basis.
