I was pa-rousing around the Internet the other day and found this great list from INC.com
INC.com is a great resource by itself, but you may find this list useful, heck it might even save you so money.
One tool pertaining to CRM and B2B marketing is Demandbase. This free service analyzes visitors to your website and cross references them with sources like LexisNexis. It then provides you with the company name that some or many of your visitors work at and for a small fee($1.80), provides you with a lead to that company.
It’s a great tool for a company of any size looking to increase lead generation; it’s even used by companies like Adobe and Cisco. If you’ve got a minute, you should look into them at www.demandbase.com, could have a pretty solid effect on your current marketing strategy.
