Being bought by PE is a death sentence. Maybe drawn out by years, but a death sentence none the less.
Often they do sell it for parts, or they enshitify the hell out of it to squeeze revenue from loyal customers. Not necessarily because it's the optimal strategy, but because truly fixing a business is hard and these are decent shortcuts from their perspective.
But that's not a given, sometimes they do truly turn it around for the better.
Prices goes up, quality of service goes down. After few years, everything goes down the drain, PE and their execs can't figure out what went wrong.
Maybe we’re Notion/Evernote? Buy Hackpad, plow a ton of money into Paper (which was legitimately good), then quietly deprioritize it.
Maybe we’re actually some kind of enterprise document productivity suite? Buy HelloSign. Plow a bunch of money into a desktop app. Pull more plugs.
A lot of smart people were trying. We made a lot of bets (too many?). None of them proved to be a second act, and the competitors eventually caught up.
