Great interface and shows real promise
Show IP address if possible
Have to say congrats, I've used something similar before in the past, can't remember the name of it!
I really like the system, it's intuitive and could be a massive lead magnet, it let's you see the URL the visitor has viewed and how long they have been on that particular URL, great for businesses to hand over to the sales team to chase down!
Would be great to see IP addresses of visitors as well, noticed some of our competitors have been sniffing around and if I had the IP of them I would block them lol!
Love the Twitter / Facebook, linked info if available, great for adding a social follow and of course narrowing down the individual my using linkedin to find people working at the company and establish contact.
All in all a great solution, it's just how much this will cost when it's out of BETA that will make it great or kill it.
I for one love it :-)
