There are a lot of mid-sized companies identified in the book _Hidden Champions of the 21st Century_. I just started the book, but it's exactly the ethos you're talking about here: these companies just focus on a niche, tend to sell to other businesses, and just stay doing this thing profitably, absolutely dominating their niche with razor focus.
I'm reading this book because, well, that's the kind of place I'd like to work. I think it makes sense to get a feel for how these places think, in order to really identify job opportunities
