This seemed to look good at first glance so we purchased 3 subscriptions. After using Leadrocks for a few months we decided that this data is quite outdated. It is still usable to some degree, but it requires further qualification of each contact. Run a test search on your company, or a company for whom you already know the employee details, and compare the results from Leadrocks. You will see that the results show people who no longer work for the company and also the people who it does match up as legitimate employees will have random email addresses on some of them that are nowhere near correct. Handle with care.
