Nice idea.

Constructive criticism:

* You need to make the signup stand out more. Even put it at the top of the page.

* Some top nav links to items further down the page are required. Looks like they have just got lost somewhere.

* Offer more features under the payment plans. Things like ssl by default, Real time metrics, 30 day rolling contract. Any thing that explains what you get for your money.

* About page. Include more images, make it a little less corporate and wordy.

* About page: without sounding racist some people will be put off you are based in india might be worth just stating your a startup and you noticed X problem.
