Off-topic, but can anyone tell me of an instance whereby a software entity was acquired by a VC firm and things turned out great?
So let's take it as read that you meant PE, in that case, it depends is the usual answer. There are quite a few examples of PE funds buying companies and letting them run as autonomous as possible with positive results and there are examples of PE funds buying a company outright or a controlling interest who then become 'backseat drivers' but without the relevant experience. In those cases - especially if the PE party consists mostly of accountants and financial people - it usually does not take long before the effects become visible. But there are a great many players and the majority of them is both well intentioned and ends up with positive results. The ones you hear and read about in the newspapers are not really representative for the PE market as a whole, that's just the news' habit of focusing on the trainwreck.
PE fund returns nX to their LPs versus PE fund buys controlling stake in struggling company and runs it into the ground after loading it up with debt. Which headline do you think will attract more eyeballs?
