Just from the top of my head, you could probably earn well at: Zalando, HERE, Mozilla, EyeEm, Blacklane, MongoDB, Zeitgold, Talon.one, Infarm (just raised a juicy funding round) + a boatload of blockchain startups
On top of that, a lot of the bigger SV startups have satellite offices in Berlin.
Yep, personally know them. But they're in Köln last I remember.
Many of the companies you mentioned (not gonna named not to get sued) have reportedly terrible working culture and/or awful recruitment process (applied to most of them). So maybe the money is compensating.
Might be true for some of them, but for the ones on the list where I know people that work there, it sounded pretty good. In the end good working culture is one of many axis to optimize on.
