How early stage? Seed round? Series A, B? Have had great experiences working with CTOs that are technical and driven. Not hard to push back, everyone is laser focused on delivering and had no time for drama. Would avoid CTOs that are nontechnical with huge egos. Really helps to have the CTOs as part of the interview process to learn more about them individually.
