even if you just want to generate hype, you should at least have some nice looking landing page, even if it has no real infos.
I'm basically afraid that you will have to buy the peoples attention twice. they will see the advert, google neobee, be unimpressed and forget all about it. If you have a landing page with "remember getting fucked by dem banksters? fuck back with neobee, comming soon" they might remember.
