Jerry's pronunciation is correct... Ah e Ah.

Say it at conversation speed and you get the familiar Ah yah.

If you ere to use the proper names of the founders of the company, it would still lead to mispronunciation, as the "z" in Aranzabel actually has the "th" Castillian lisp sound and most people ould not kno better.

Let's call it a day and be happy with Ah e Ah.
