For those seeking info. on private equity Venture Capital (VC) is one of the biggest components. This is "value add" type of creation, in my opinion. They take people with an idea, give them $$$ and management tips, and then watched their garden grow.
I don't see as much "value creation" in private equity as I do in VC work. Too much private equity (LBO stuff) is financial engineering/optimization. While some companies are PHENOMENTAL at changing management structures, practices, etc. they tend to be more evolutionary vs. revolutionary.
