An extrovert is typically better at marketing and sales, namely for the social aspect. For someone like me that's an introvert and extremely shy around new people, I gain XP by tackling technical problems.
That doesn't mean technical people can't be a visionary too because you'll definitely need it. Someone that can get a complete grasp of the scope to tell you when a decision will lead you into more or less technical debt. You can make all the right business decisions and still fail miserably if you make wrong technical ones.
I'm likely not telling you anything you don't already know but I just wanted to make sure you weren't compartmentalizing things too much.
I think I'm a visionary technical person. The problem I'm addressing is based on two decades of experience in enterprise configuration management - solving the forest/trees problem of seeing small technical changes in the context of bigger business changes, and/or drilling down from the big business tasks to the technical details that implement them. It's a boundary-crossing technical issue that's near and dear to my heart.
A good CTO could devise their own implementation path rather than following mine, but that's not really "vision". That's about how it works, not why it needs to exist. I can do the "how" myself, but I don't think it's a good use of my time and focus.
Hey, configuration management is something really interesting to me. I don't suppose you'd mind emailing me with a link to your startup (email in profile)?
