My former company subscribed to ITS Profiles (www.itsprofiles.com) back in 2003. I am now the CMO at another company and am looking at signing up as part of my effort to rejuvenate our lead generation program. However, before I do I want to be sure that they are still the best service. Please share your experiences with me. Thank you.

I am a director of marketing at EDS. We have been using ITS Profiles since 2002 and are more than pleased with the results. I have found that they have only improved since we first signed up and that they are the only company with in-depth profiles and org charts on all 500 of the Fortune 500. Hope this helps.
