On second read, I get it. Thank you. That's big-thinking "marketing" to me, but it's there. :-) As long as a founder themselves owns that sort of marketing role then it gets the attention it needs and (still) I think the other items on the list need to be guided/gated by this marketing to a large degree even from the first days.
