The landing page is fantastic. I know exactly what this product does, and I can see where it would fit into our organizational needs, all without any effort on my part (I didn't even need to scroll, although there is more detail when I did).
The product is sure awesome, but since you're discussing the design of the homepage, I think the typography might need some more work.
And if you look on [this page](http://www.opp.io/About), the color palette as well :/
Hi Humpt, thanks for the comment. We will definitely iterate on the design including typography, colours in the mockup, color/whitespace balance etc. For now, most important to us is that people get the concept of the product.
