So I'm curious- I can understand why you'd want a fractional CFO or CMO, but what does a fractional CTO even do? In my mind a CTO is either someone who manages multiple teams,or someone who manages a team that does 'de novo' deeply technical work. It's difficult for me to see how either of those would work part time, or really that that their skill set would be applicable to a company that can only afford part of their time. In a small team,why would you hire a fractional CTO as opposed to just making sure your most senior engineer is able to mentor the juniors?
