Women reported it, right? The Times article describes it. Women seeking jobs were propositioned and then denied jobs after rebuffing, sexist comments were made while they were fund raising and suggestive texts were sent. It doesn't seem like rape level stuff but it's still bad and unacceptable.
It's never a good idea to approach someone romantically if there is some kind of superior/subordinate relationship. it just seems really messy with some sort of VC type relationship too, maybe almost a worst case scenarios.
