Advanced Circuits is who Adafruit uses. I know because I emailed them about this a while back.
That may be true, but Advanced Circuits actually farms out their PCB fab to various other houses. I happen to use one of the fabs that Advanced Circuits uses, but they’re within driving distance so I save time and money on shipping. Plus, I get to tour the facility in person.
