Enecto provides a B2B Identification solution using a code snippet thats part of your website. It matches the visitors IP address with a pool of IP addresses in its database. If there is a match, it identifies the visitor from such and such company.

I’ve been looking at LeadLander every now and then. I find it’s a very cool product with its ability to track visitors. It does a reverse look-up of the IP address to distinguish between corporate visitors and “home/ISP” users. The idea being that in B2B sales, corporate visitors would count more.
