On the face of it, it is positive and that along with the other hirings suggests belief that revenues and the number of clients will be increasing. It could just be a belief that things will take off through Marketo/Oracle, or it could be due to landing a large contract or jv. More likely one of the latter 2, I think.
The controller specifically could also be in anticipation of a future departure of Jeff, or a reduction in Jeff's role in the future, although since it is along with the other hirings it seems more likely to be due to expected near term demand improvement.
Thanks for asking, ct.
