I always find this interesting! It takes digging to get the answers, but there are a few resources out there to explain some of it. I can't think of them off the top of my head, sorry :/ For example; yes, Rails or Django is common to rapidly whip things up at an early-stage startup. Data Science and ML companies will lean towards Python because it's the main building block of their product. No hard and fast rules, of course; you'll often see Scala at these companies too, given it's relationship with Spark. Anyways, I'm always trying to understand and seek out the answers to the exact questions you have.
