When you were larger, you state: "At this point, I believe technical co-founders have a binary choice: Stay on the technical track and hire a professional manager (usually given the VP of Engineering title), or give up coding and focus on the management aspects yourself. It really isn’t possible to do both." Since you chose the management track, what did you do/who did you hire (in what levels) to take care of engineering at the level you were previously doing? Or were you effectively functioning as a standard IC so any developer could take your role?
