This is very confusing to me. I'd say that maybe that's typical for other situations, but resigning effective immediately because the offices wouldn't be moved

This is very confusing to me. I'd say that maybe that's typical for other situations, but resigning effective immediately because the offices wouldn't be moved sounds very, very odd. I would be really disappointed if a CEO left day-of rather than at least allow a transition period where a lead investor didn't have to step in. (Unless it was the board that wanted him gone asap?)
