Almost every new company starts with the address a founder already has. It goes on the incorporation paperwork because something had to, then onto the first invoice, then into a supplier’s database, then onto the website because the footer looked empty without it. Nobody decides this. It simply accumulates.
Two years later that address is in places you cannot remember putting it, and it is still where somebody lives. Choosing the address deliberately, early, costs an afternoon. Unpicking it later costs considerably more.
