What kind of modeling does NationBuilder provide for voter data?
NationBuilder's addons include "donor intelligence" and "social intelligence" in addition to the free voter file for campaigns. What are those addons and how much do they cost?

Through our Austin-based voter data team, NationBuilder is able to offer voter file data - or "voter intelligence" - at no additional cost to most of our political campaign subscribers. This free voter data model with a NationBuilder subscription lowers barriers to access for down-ballot and primary candidates.
Political campaign customers using our voter data can also purchase targeted data called "donor intelligence" and "social intelligence." The add-ons must be subscribed to at the same level as voter intelligence - if you have 400,000 voter records, you will need the donor and/or social intelligence to cover that entire data set. Again, our subscription and database-size pricing model makes this modeling data - traditionally only available to the most well-funded campaigns - more accessible. For example, a Congressional campaign would pay a database subscription rate of $79 plus $600 a month with donor modeling appends. A smaller race could pay as little as $19 a month plus $25 a month for the donor intelligence. You can review the detailed pricing model here.
Donor intelligence includes information on party loyalty, Democratic and Republican donor propensity, household income, occupation and more. Both donor and social intelligence are accessed in People > Advanced Search and are helpful for making selects in the voter file. Political consultants tell us they value the donor intelligence in particular to help their candidates have confidence they are targeting their asks at voters who can afford to give and have a history of doing so.
Social intelligence includes consumer data modeling and more than 40 check boxes for narrowing voter selects by interests such as sports, social networks, food and music.
