I would agree, purely on aesthetic grounds "1Password Park" sounds terrible. An example of how this can be done better would be something like the Institute for Contemporary Art in Richmond, VA [1]. The building itself is known as the "Markel Center" (Markel being the large insurance company that paid for it), and they have a small sign out front. I don't mind that at all. It helps that the name is a proper name, after the founder of the company, and it's not a well known B2C brand.
