So the most important link on your entire web site is effectively still invisible. What message does this send to your potential customers? It's the Internet equivalent of leaving a message on an answering machine without leaving your phone number.
I don't understand how you can post this screenshot[2] and talk about information density. The information density of your current product is very low.
But the worst problem is the incredibly low contrast of your UI. Look at that screenshot again. Look at the links on the right side of the screen. They are barely readable on a full-size, matte monitor indoors. Now imagine someone using a glossy monitor facing a window during daytime. Imagine someone using a laptop with a glossy screen on a desk with fluorescent lights overhead. Imagine someone using a tablet outdoors. Might as well try to read a cloud floating overhead! The NN Group also has an article[3] about this, and your screenshot looks as bad as or worse than all of their examples of what-not-to-do.
Where are these professional "designers" learning to make these horrible mistakes? Why are they still employed in the field?
