After reviewing your site I found there was a potential for confusion with openup.com which is a completely different site. How does the name reflect what you are providing? Would be good to explain this somewhere.
I also found the About Us page was way too vague and the FAQ's, while better, still did not really describe the value for the various stakeholders. The tabs are almost hidden down at the bottom right so the first impression a person gets is that I need to sign up to find out what it is all about. That can be a tough sell today.
Suggest shouting the message of what you offer and why you're offering it on your home page so people can see the value before they commit a link. People are hesitant to give you a personal link before they know what you can do for them.
I, like the previous response pointed out, that you should really focus on the companies that would be willing to use a new methodology for finding potential employees then perfect the process with a few clients.
Finally, when I looked at the Contact Us page I found it very sterile. There is really nothing on the site that indicates who is driving this concept and therefore gaining trust may be difficult. People want to exchange trust before they commit personal information. People buy from people the like and trust, what can you do to encourage that trust?
