Hi,
Really like the website, while I admit I haven't researched the niche unless your focused on only a tech crowd, it would likely make sense to re-word bits like "Premium item for early adopters: " to say "Limited time special for 24 hours only" since the general population is going to be put off by words like early adopters.
In terms of marketing itself, I can certainly create you a social media marketing campaign that converts to an e-mail list to use pre-launch to raise traction for the crowdfunding campaign.
Send me a message and let's have a chat.
James
