like it a lot the ajax when you click on a company name for the info is a cool bit. IMO you should make a header that spans the entire way accross the top, aside from that it looks very clean and professional.
Interesting concept with a simplistic and self explanatory layout that's intuitive to navigate. The font of the companies in the listing is a bit small, however, for your purpose, you can't really go much larger.
The logo does certainly not represent your idea well, i'd revisit the design there and come up with something more "driven" and stylish. Other than that, nice project!
