I took a call from this number after a couple of missed calls.  I had registered on their website for free content and they told me that it's their policy to follow up and ensure that the information was received and make sure that it meets the need.  I asked how they get phone numbers and they said either from people that register or through Hoovers (the largest lead company in the world)They are an Information Technology research firm (not marketing but they provide research and insight) to IT people.  If you're not in IT it's a waste of time - I actually did my research and they're ranked in the Top 10 IT research firms believe it or not.  So I looked at their service (I'm in IT and it sounded relevant) and it's solid.

Are you stupid? Read the comments. People ask to be removed over and over and they still call back.

I finally picked up this call and wanted to know how I got on thier list.  You enter your phone number when you download thier free stuff, and they call to do a follow up to make sure I got it.  Not at all what I was thinking. After all of that I ended up getting thier service, and glad I did.  They saved me from having to cut staff this past year

These guys call all the time. Don't leave a message.  How can we report them for unsolicited phone calls?

You know all you have to do is say remove me from the list right?

At first I avoided the call thinking it was just the usual telemarketer or someone calling to do a survey. Turns out they are a huge help for me and my organization. They are an I.T Research and Advisory firm.
