About us
Since launching our virtual incubator, Greater Sum has supported over 100 nonprofits working in education, health, environment, and community development.
With our help, they’ve clarified their financial models, built out strategic plans, secured additional funding, and expanded their programs.
Each year, we select a cohort of “promising practices”—alumni who are introducing scalable models for school equity, public health access, environmental resilience, and more. These aren’t just good ideas; they’re sustainable nonprofit growth stories, made possible by targeted support early in their journey.
