Any particular reason for switching every 6-12 months and is that common practice? Trying to get a sensing here.

Just me :)

First StartUp was amazing, super professional people. Run out of money and laid people off (StartUp still lives and grows now)

Second StartUp was led by mid-twenty Bros and not the culture I wanted to be part of.

Third StartUp led by people bought in by a bigger corporation. Had no idea how to run a company. Best team I have ever worked in but worst business I ever worked in as well. Almost everyone left after being there for 6 months.

Fourth StartUp ad tech industry. Learned a great deal, solid co-workers, but had enough of "We are a cool StartUp" vibe and went freelancing.

General speaking, I don't dislike StartUps, but oh boy I am too old for this now (35 years old).

That's still quite the journey! And you must like Berlin enough to working there, I suppose. How's the tech scene there like?
