I totally agree with you that a typical CEO would not put up with this at all, but then I don’t think this is a very typical situation :D I would assume she knew what she was getting into. He named himself CTO so it’s not like he’s no longer involved in the company, and the CEO can’t really ‘overrule’ him on any product decisions or anything else since he’s technically also her boss.

Now, if he’s smart he will hopefully at least take her opinions/guidance into consideration, but 🤷
