About Us
Who we are
Making blue waves in progressive fundraising
Since early 2017, GA Campaigns has been on the forefront of using data to drive fundraising for progressive campaigns, causes, and organizations. As the political landscape has grown, so have we – initially born in a call-time room as a way to make the call-time process more effective, our service has expanded significantly. The ongoing expansion of our database through private acquisition of campaigns, non-profits, and other left-leaning causes, has fueled our growth and development as a company. We’ve become experts in digital audience curation, mobile phone lists, bulk email acquisition, and fundraising strategy. Following the 2020 cycle, our database includes information on 20+ million left-leaning American donors with disposable income.
In the 2020 cycle, our hyper-targeted and personalized lists helped more than 1,000 campaigns raise more than $228 million from 3.1 million contributions nationwide.
