Since 2020, the Democracy & Power Innovation Fund (DPI) and our learning partners in organizing, philanthropy, and academia have been innovating a new approach to measuring how organizations build power to win change.When we seek out the drivers of progressive change in almost any state, we find a handful of entities that organize bases of people who deliver that power over and over again in legislative and electoral campaigns to win change across issues.The problem is that the work it takes to build and continue growing such an organization’s power over time has been largely invisible.
