Maybe just my perception, but I just have the impression that TK is way out of her league. I had heard-- maybe incorrectly-- that she had a major sc--w up in a previous role and had to bail.
Also, look at the track record. Never more than pretty much 1-2 years anywhere. You know what kind of impact you make in a big organization in 1-2 years? Not much. You scratch the surface, that's about it in a year. That should tell you something. In 1-2 years, you can do all sorts of garbage and the real impact isn't felt until after you've bailed.
Oh, and one more thing. So she's been in place for a bit. Has any direction changed from what SVB put in place a few years ago? Nope. So, what value or insight we gonna get from TK besides more photo ops and promotions of the buddies she brought in.
