As an Account Executive I was able to use this tool daily for prospecting and generating new leads/opportunities. The data could be used as far back or deep into our database with very little effort. There is nothing specific that I dislike about lead family it's simply because we were not using enough of its features. If you are looking at lead generation tools then give them a try! We solved problems related to cold calling by giving us more accurate prospects who can turn to sales faster than other methods available out there today. This allowed us to generate revenue quickly without wasting time reaching potential customers outside their target market.
