We have a fairly large and fast-growing Salesforce.com database, but we are frequently missing pieces of data. Could be email addresses, could be phone numbers, etc. The business problem being solved is: making sure our data is as accurate as possible, to optimally fuel downstream processes like sales, marketing, etc.
Re: benefits... previously we were addressing this problem with slow, expensive, mind-numbing manual processes that our people hated to do. We are able to knock out a huge chunk of this grunt work quickly at a low fixed cost that saves us time and money. Review collected by and hosted on G2.com.
