If you are a C-Level executive, no matter what the position, you will need to be able to manage people.
The C-Suite is responsible for setting and steering the vision of the company. In the case of the CTO, that is the Technical Infrastructure (Engineering, Product, and in lieu of a CIO, Security/Operations).
As the company scales, they will have one or more departmental VPs reporting to them (see above), and be responsible for keeping those on track.
Many technical co-founders are *not* CTOs, but are actually senior engineers (and there’s nothing wrong with that). Refer to the Peter Principle for more understanding as to why there’s an innate desire to promote them anyway.
