Little Sis is a grassroots watchdog and strategic research organization, connecting the dots between the world’s most powerful people and organizations, including elite think tanks, secretive Super PACs, revolving door lobbyists, corporate fat cats, and paid-for politicians. It supports campaigns by power-mapping decision makers and their financial backers and offering a free database that highlights connections in government and business. Successful campaign examples include revealing who profited from Ferguson, how Betsy DeVos’s network functions to kill public education, and who is banking on the Dakota Pipeline. Through training and tools, Little Sis helps groups build their own power mapping capacity and combat the financial interests that threaten our democracy.
