To those who don't wish to provide their email address without understanding what the company is:

"Classfy is a marketplace that makes it easy for anyone to buy and sell anything in Bitcoins or Dollars.Forget about exchanges. Just buy and sell."

From a Google search description.

Yes. That is not completely correct. We can build any marketplace on top of the platform. We wanted to see the interest of the Bitcoin community in having a dedicated marketplace. But Classfy is not limited to Bitcoin. We actually want to start with a marketplace for wine first. You pay in regular currency :)

It might be a good idea to have a bit more description on your main page, since not many would be willing to provide their email address without understanding what the product is.
