Jeepers, I worked on two startups where I met a “business” person (first was a finance-type, second was a doctor, and we (I) proceeded to do all the work in gathering requirements, building prototypes, etc etc. In both instances, neither of the “ideas” people had any experience of being in any kind of project, and both wanted to discuss equity way too often. And in the event, neither of them as CEO did a blind bit of work. Classic management-by-walking-around. When I suggested to the second one that we might want to find an actual CEO he went nuts and started raving around how he had done all the work of setting up the company and coming up the idea - reader, there was nothing on paper, he hadn’t written anything down, he just wanted to explain it and have everything magically happen.
