Who We Are

Business People Meeting Growth Success Target Economic Concept

Oh, and we are proud ATLiens (aka we are from Atlanta, Georgia)


The Synthio Story

In order to tell you who we really are, we must start with who we used to be. We used to be a company called Social123. Social123 started as a social listening tool, but after working with thousands of marketers, we realized that there was a much larger pain point that no vendor was able to address. Our clients were constantly asking us where to get more data, more contacts, more email addresses. So we pivoted to meet the needs of so many marketers and sales professionals. We set up an all-star team to build the most cutting edge algorithms to gather and index our very own contact database, that is constantly refreshed in real time.


We remained Social123 for about 3 years until November 2016 when we became Synthio. Our old name reflected more of who we started as than who we are today. Today, we are the only data solution that automates the data cleansing process while also providing the richest firmographic and contact data available for appending or origination.


We automate the synthesis of data sources and datasets seamlessly so marketers don’t have to.


Simply put, we make your data bigger and better.
