FusionIO, makers of enterprise SSD storage, are in Salt Lake City.

Companies are global, with bits of company here and there.
Even the workforce has more than one color of skin. Amazing.
Flash chips can be made in a Japanese plant (bare silicon die),
then packaged and tested in China. Just like many other chip
companies do production in two different countries (silicon
in one place, package and test in another like Malaysia).
Motherboards are designed in Taiwan and China, but also
in Folsom, California (Intel).

Intel doesn't generally do PCB production itself, and that
is contracted out. And not the same company wins the bid
each time.
People do design with IP (intellectual property) blocks.
Where are those designed ? Why, right in the city I live in.
And in cities all over North America.
Look harder.
