they are basically a lead generating tool. the way it was explained to me is that you pay to be on a list on their website. they have a list of customers that use their service such as CBRE that you can view. their customers go to the site, sign in and request info for the services they need, i.e pressure washing, window cleaning ... etc. they then get the list of everyone in that demographic area and send out rfp to them. there was no guarentee, just the fact that 20+ bigger companies use them. I will look for a link to their site.
