About Influence Explorer

About Us

Influence Explorer is a project of Sunlight Labs, the technology arm of the Sunlight Foundation.

Our Data

Real-time Data

Much of the data found on Influence Explorer is collected and parsed by the Sunlight Foundation for realtime consumption. Our goal is to make this data available and searchable with a little delay as possible, offering users the opportunity to track disclosures as they become available. The necessary compromise, however, is that there is much less human curation of this data: we take a light-touch approach to automating data cleaning and reconciliation, but make no guarantees as to the absolute accuracy of the real-time streams. This is the first draft of the history of influence. For the final word, please see our historical data offerings, which have been processed by other organizations.
