What is the role of an Engineering Manager?
plinkplonk: "I have been asked to be a much more proactive manager who actively keeps tabs on the developers and pushes the project forward."(This may sound flippant but that isn't the intended effect.) If you are the technical co founder of a startup and the early hires aren't managing themselves well, maybe you hired the wrong (type of) people?Hard to give useful advice for such a generic/vague situation. But if I were you I'd just replace them with more self directed people. In   an early stage  startip I wouldn't want to do too much people management especially if it distracts the tech co founder.My 2 cents.
