“ I purchased the library set from these guys and to be honest it was fantastic. It was super detailed and the contact data was perfect. There were a couple of errors I spotted but the impressive thing is they fixed it right away.I couldn't recommend ListBuilders enough”

“I used a Listbuilders dataset of companies in the haulage industry and I was very impressed with the accuracy. I had tried a few other lists, and making my own using some online tools that promised the world, but nothing came close. They were also super helpful, 10/10 would use again.”

About List Builders

Learn more about List Builders’ data sources, use cases, and integrations.

List Builders in a Nutshell

ListBuilders was founded in 2022 to help businesses take control of B2B growth! Our manual data collection methods deliver unparalleled accuracy and depth of company and contact information.

It was created because our Founder, Mario Lucas, was fed up with paying for data subscription services that delivered inaccurate data and just ended up wasting time and money.

We are now a fully remote team of 6 people that can call upon additional assistance as and when required to complete projects. Part of the team is Paul and Dennis who lead the data strategy team as well as Heracles who is Head of Data Science.
