I was the CTO of an early stage startup that had a team of 3 developers. As a CTO your role is to have the vision of the entire platform, to pick the best stack that will get your MVP done, to think of best solutions to scale the system after you get traction. The CTO needs to have a deep technical knowledge and I think you can not do your job well if you do not code, test new technologies, build proof of concepts. If you sit around all day and just code review you are doing it wrong, you become just a glorified manager. You need to give your team the best technological advice and help them when they are stuck. Most of the time I wrote proof of concept code and tested out some libraries before I guided the team in using them.
