I've seen firsthand how PE ruins startups. I joined a seed co and our founder went with a PE firm rather than a VC for our next round. The VCs were upfront about job cuts but the PE investors did not say anything until they took over. Needless to say, the founder got a good paycheck but we were left holding the bag. It was a bloodbath and they completely ruined the culture, product, morale, and any semblance of growt…
The sales started to slump for the product I worked with, and they decided to make up for it by raising prices. They figured they would make more money than they lost by alienating customers. The other thing they did was drastically ramp up license compliance shakedowns (one of the shadiest practices I have seen in the industry).
The product and company are still around because bits got sliced up, spun off or sold off. PE no longer has its tendrils in it, although I am not sure who does now.
