alt Hacker News> I can't think of any other time something good has come out of a private equity roll-up.
Just remember bad news sells. I'm reasonably sure there are a number of other cases where this happens, likely most. However they are not big news and not memorable so I can't cite them.
If it happens all the time and it's positive, you shouldn't need a news story to confirm it. People should just be able to think of examples.
Certainly I'm able to think of plenty of terrible results from private equity take-overs from my own personal experience as an employee or as a customer.
