The phrase "has its seat in" is often used to describe the location or headquarters of a company or organization. However, there are many alternative phrases that can be used to convey the same meaning. For example, one could say that a company "operates out of" a particular location, or that it "is based in" a particular city or country. Another alternative might be to say that an organization "calls [a particular place] home," or that it "is headquartered in" a specific location. Depending on the context and tone of the message, using any of these synonyms could help to add variety and nuance to one's language.
