The Sentinel Project
The largest open graph of congressional influence ever built
463K entities. 7.3M connections. Every dollar traced.
Sentinel maps the full network of political finance — campaign donors, federal contractors, lobbyists, legislators, and dark money flows — into a unified knowledge graph. Machine learning models trained on this graph detect influence patterns invisible to manual review.
