Yeah I’d have to agree with caffeine. Pier I think that you are misinterpreting their goals. The fact that the project was posted to kickstarter which is essentially a web version of a bake sale, signaled to me, at least, that they are not in the hunt for big venture capital bucks right now, but are looking to off load part of the financial burden of starting a small company. All money donated is essentially a gift, you get a gift in return, sure, but you’re giving the money knowing that the vast majority is going to them to do as they please.
As far as the video being a little hokey, cute guy, cute girl, yeah I guess, but that’s subjective, it’s not like they hired out actors and hid behind the camera. As far as it being childish, I don’t see that, in fact I think it’s a very mature well thought out video for their purpose: ie. they want complete strangers to like them enough to want to give them a gift.
