Far too many great ideas for solving pressing social problems are not being applied at the scale they deserve, because thousands of nonprofit organizations are teetering on the brink of collapse. Of the 300,000 nonprofits in the United States, two-thirds have an annual budget of $500,000 or below, which does not allow them to expand their operations or scale their solutions. Fundraising is by far the biggest challenge for the sector, even for the most successful organizations. In a survey I conducted of the leaders of over 200 top-performing social entrepreneurships, 81% of them identified access to capital as their most serious concern. If an organization can’t reach sustainability, which I define as reliably raising around $2 million in annual revenue, the chances are high that it will eventually stagnate or fold.
