I'm not the target audience but wanted to chime in with a few things about the design and copy:

* Why is the iPhone 3 times larger than an iPad? I got a little confused the first time the site loaded trying to figure out what the giant black device behind the iPad is.

* "Signup Now". English isn't my native language but I'm fairly certain "signup" is a noun, and you want the verb or "sign up" instead

* "Zigzag Cloud has powered built-in analytics". Powered by what? Or is it "powerful"?

* Love the logo and the colour scheme of the site!!
