I've been so proud to work with Grassroots Analytics - both the campaign and nonprofit arms - on the last two projects I've managed. Their data is second to none, and their responsiveness, assistance, and quality of work is unparalleled. In both cases, I've been looking to grow fundraising programs while on a limited budget, and the folks at Grassroots have been so helpful in helping us navigate that terrain. In my last campaign, we grew an email list from 200 to nearly 20,000 and raised over $300,000 with the help of Grassroots Analytics' data.
I recommend them to everyone I know at every chance I get.
