Dash's logo is the type of logo that is very popular not only in crypto but in general in graphic design in world corperations.

Or Microsoft's logo is not letter based but a shape.

Overall you need to distance yourself from the "coin" shape. It's a cheesy altcoin meme that devalues your image. It should be a simple shape or two letters "AI" floating on a white background.

As far as the site, look at Monero's:
https://getmonero.org/home

It has a menu bar up top and a simple, clean, professional interface. It should be a quick and simple reference for people to learn about your product. You current site is convoluted and requires people to scroll through flash animations that look cheesy and waste their time. A lot of people have mobile devices that will struggle to even load that. I will give you some references for someone who can do the work for you.

As far as promotion Coindesk is great. I would go with them first if you have to choose one. Also posting in /r/bitcoin yourself as the lead dev isn't a bad idea. They are receptive to legitimate projects such as this. It's a great promotional vehicle. Storjcoin and Monero are well received there and I think your project will be as well.

I'll add more later as I get it.

EDIT: Just got a referral for you from my team: http://www.cryptodesign.net/
He did Mintpal's logo etc. Look at his website for an idea of simple and effective design.
