I also have no complaints about my pay ;) But my experiences with big companies have left with me little desire to talk to them. It's always been a frustrating experience full of low-ball offers and treating me like an idiot.

Every time I've dealt with big-company salary negotiations it's felt like buying a used car. "Oh, we absolutely cannot go higher than that ceiling" "Welp, sorry then" "No wait, we talked to our VP..." - startups (or really, just smaller companies) have always been much more transparent and much more direct in their dealings.
