What Sunlight Foundation does

The Sunlight Foundation was a national, nonpartisan nonprofit organization founded in November 2005 by Ellen Miller and John Wonderlich in Washington, DC. Its mission was to make government and politics more accountable and transparent through civic technology, open data, policy analysis, and journalism. The organization operated for approximately 15 years before ceasing active operations in September 2020, at which point its website was converted to a static archive.

The Foundation's core programmatic work centered on three flagship initiatives: the Web Integrity Project (which monitored changes to government websites to detect shifts in public information and policy), Open Cities (a program assisting municipal governments with community-centered open data and open contracting), and Tracking Trump's Conflicts of Interest (an investigative project monitoring presidential business entanglements). Supporting products and tools included Sunlight APIs (programmatic access to Congress and government transparency data), the Sitegeist mobile application (iOS/Android neighborhood data infographics), the Open Data Policy Wizard, the Tactical Data Engagement Guide, the Community Engagement Impact Framework, the Roadmap to Informed Communities, Open Data Guidelines for Procurement, Data User Groups playbook, and the Open States Transparency Report Card.

The Foundation operated as a 501(c)(3) public charity funded by grants and donations rather than commercial revenue. Reported funding included approximately $2.53M from the Omidyar Network (2011) and $4.0M in an additional round (2013). Its go-to-market was community-led, relying on direct municipal partnerships (Philadelphia, Los Angeles, Louisville, Pittsburgh), strategic alliances with the Open Contracting Partnership, academic co-hosting of hackathons with Stanford and Columbia (Datafest 2013), and multi-channel civic engagement through blog content and social media. No subscription, licensing, or transactional revenue model was used.
