Also: these terms are completely reasonable and under normal circumstances if I were doing a startup – and this valuation made sense – they'd be terms I'd be happy to take. For the avoidance of doubt, all of this is about the marketing, not the substance; the substance is above reproach.
As you say, speed, costs, rights (board seats, information, pro-rata, drag-along/tag-along, you name it), pref structure, etc are all real things. I just prefer addressing those all up front.
