Overall, we have had an exceptional experience working with LG. They do a great job at providing what we request in a timely manner. We have had no issues with them as a vendor, and they have been willing to help us as needed when identifying new and/or different types of list data that we use for marketing. We would recommend them to other businesses as they are able to develop, maintain and provide a quality B2B relationship with their clients and customers.

"I have been using List Giant for my business's lead generation needs for over a year now, and I can confidently say that it is the best place to get leads. Their database is extensive and up-to-date, and their customer service is top-notch. List Giant's user-friendly interface allows me to quickly and easily filter through their database to find the leads that fit my specific criteria. The accuracy of their data is impressive, and I have seen a significant increase in the number of high-quality leads that convert into sales since I started using their services.
