What We Do
Proposium helps nonprofits find foundation funders that are already giving to organizations like theirs. We use publicly available IRS Form 990-PF data—over 336,000 grant records—to match your organization with foundations that have a history of funding similar missions, programs, and communities.
How it works: You add your organization and tell us about your mission and focus. We analyze foundation giving patterns and surface your top foundation leads: funders who have repeatedly supported nonprofits like yours. You see match scores, typical grant sizes, and how many similar orgs they’ve funded—so you know who to approach before you spend time on applications.
Our goal is to make foundation research faster and more strategic: know who to ask, and why they’re a fit, from day one.
