Startup, but not a tech startup.

>Maybe the difficulty in categorizing is that every company today has to use technology.

Yep, this is exactly what I was trying to get at. That being the case, it seems more accurate to shape a definition of "tech" companies based on output (i.e. products/services offered) rather than input (i.e. tools employed).
