No-ad-spend companies are hard to come up with, some possibilities are everyday necessities with very few competitors like salt (but I think they advertise a little), or utility monopolies (I don't think my local water company or garbage collection company advertises, but I haven't checked. Maybe they advertise to the government offices that select the companies to use?). Pre-internet days, it would be easier to be sure some businesses don't advertise (neighborhood convenience stores or laundromats, for example, that get enough foot traffic to not bother advertising), but with the ease of throwing up a website nowadays (which should count as advertising), this can no longer be assumed.
