I actually like the Gary V one. I think using voices that people are very familiar with is helpful for showing the ability of the product. It allows me to A-B the voice with how I know Gary's voice is in my head.
I would respond to the investor with, because it's not about quantity, it's about quality - quality of work AND quality of life. In 2-5 years time, I can't imagine the product would be any better due to that extra day every week.
20 years ago, when I worked at CompUSA, we used to have this bin of budget software. In it, you'd find things like "3D Home Design" software, game clones, and Pagemaker wannabes. People used to ask all the time, why do I need to pay $200 for X when I can buy this one in the bin. They'd of course be cheapos, buy the one in the bin for $9.99, and then one of two things would happen, either they'd realize, wow, this is crap, and come back and buy the $199 "real" software, or they'd come back and ask a thousand annoying support questions on how to make the crap software do what they need. Some things never change.
Are you a freelance/contractor? Are you looking to add to your skill set in general? Do you know Javascript at all? If you answer yes to one or more of those, I'd say it can't hurt to learn Node.js.
FWIW, I would move the mailing list form out of the main call-to-action area as it visually interferes with the "Try for Free" button. Maybe move it to the black bar below that and center it. Could possibly reduce the size of its elements a bit too.
