This. I work for a mid sized adult company for over 4 years now and it definitely feels like a start-up. We try new things a lot, very little bureaucracy and a lot of interesting challenges. The industry is indeed secretive because of the way outsiders see it. But that can also be an advantage, you don't need to worry about a VC funded startup that will kick you out of the market by burning a ton of money. Only thing I worry about is the label I'm getting but I guess I will find out later on about that.
