The Sentry is an investigative and policy organization based in Washington, DC, focused on disrupting multinational networks that profit from violent conflict, repression, and kleptocracy. It traces illicit finance from war zones to global financial centers and provides evidence and policy options for governments, banks, and law enforcement to hold perpetrators to account. Since its founding in 2016 by George Clooney and John Prendergast, it has produced investigative reports and dossiers on actors tied to grand corruption and advocates for financial and legal pressure, asset recovery, and targeted sanctions. The Sentry operates in the international affairs space, working with governments, global banks, and other public and private actors to apply leverage that promotes human rights, peace, and anti-corruption objectives. It has pursued notable partnerships and organizational changes, including a merger with Not On Our Watch in 2019 and collaborations such as the 2022 Castellum.AI partnership to screen for corruption ties. In 2025, the organization appointed Justyna Gudzowska as executive director, reflecting ongoing leadership development.
