There's a typo in your "Take a new approach" panel. The URL in the image says techcrunch.com/stapy-files-for-ipo. I think you want it to say techcrunch.com/staply-files-for-ipo.

I agree with the other comments suggesting that it is not 100% clear why someone should sign up (from the landing page alone, at least). I think that a panel focusing on some of the use cases (that you've nicely identified on this HN thread) might make your service clearer, and help motivate more users to sign up.

Best of luck.
