Recommendations to others considering NGP VAN:
It really is the gold standard for democratic campaigns. I believe, however, that part of the agreement means they get to keep any data your campaign harvests. It's worth investigating that if ownership of your data is a chief concern. Review collected by and hosted on G2.com.
What problems is NGP VAN solving and how is that benefiting you?
VoteBuilder makes it easy to create targeted lists for phone banks or door-to-door canvassing. You can target voters based on their party, voting history, age, gender, specific issues they've indicated are motivating factors, and more. Additionally, you can create and assign codes specific to your campaign -- attendance at a certain event, answer to specific questions, etc.
The result is an exponential improvement over simply flipping through the phone book. Your campaign saves time and energy by focusing efforts on the right voters. And it enables you to track these voters over time, staying in touch up to election day. Review collected by and hosted on G2.com.
