If investors offered me counseling services, I don't see how I'd feel comfortable taking them. Not because I have anything against therapy (I used to regularly see a CBTist, and still employ the techniques personally all the time), but because I would have an incredibly hard time believing in both the VCs' wherewithal to hire such a person on more than their perceived celebrity within their professional/social circle and also I'd struggle in fundamentally trusting that mine and the therapist's incentives were properly aligned.
It seems like it couldn't possibly produce a dynamic that's much different than say corporate HR. Wherein the helping hand extended to the employee is always beneath that of the one that's protecting the company.
But, maybe that's just me exposing my rank cynicism, which by some measures is a personality flaw in its own right.
