Small companies. When you manage to find a place in a small company, most truly make you feel like your work is rewarded. The best I've found are groups of friends having fun with something they can profit off of, for example Team Cherry in the video gaming industry. They're a team of 3 that made what is widely known as one of the better metroidvanias, Hollow Knight and had a best-selling spot on Steam for a few months, which I can only imagine gave them so much more money out of a $20 game then one $60 usually makes.
