Identify Companies visiting our Website

Hi all,

I’m in my Piwik trial period right now.

I am trying to figure out how I can see the names of the companies, that visited my homepage or even create a segment that only shows companies with its names.
Google Analytics can partially do that and a German tool I am testing right now (WiredMinds) can do that, too. So I ask myself if I just miss that function or if it really isn’t available.

I appreciate your help!
