About Signal990
We believe foundation research should be built around relationships, not just databases. Signal990 helps nonprofits discover aligned funders, map connections, and manage every relationship from first research to funded partnership.
Our Mission
Signal990 helps nonprofits find the right foundation funders by combining IRS 990 data with network intelligence. We don't just show you a list of foundations — we map how your board, peers, and network connect to each one, generate AI research briefs, and give you a pipeline to manage every relationship.
Most grant research tools focus on search and data. We built Signal990 because we saw a gap: nonprofits don't just need to find foundations, they need to understand which ones are genuinely aligned, how to reach them, and how to manage the relationship over time.
What Makes Signal990 Different
We start with IRS 990 data — the most comprehensive public record of foundation giving — then layer on intelligence that no other platform provides.
Network Intelligence
We map connections between your board, peer organizations, and foundation decision-makers — so you approach funders through warm relationships, not cold outreach.
Research Briefs
Generate an AI-powered dossier on any foundation — alignment verdict, comparable grantees, recommended ask range, and a strategic approach path.
Relationship Pipeline
Track every foundation relationship from initial research through funded partnership — with AI-generated next steps, deadlines, and team collaboration.
The result? A tool built for how fundraising actually works — through relationships, not just keyword searches.
Data Sources
All data in Signal990 comes from publicly available IRS 990 filings. These are the official tax forms that private foundations file with the IRS, and they include a complete record of every grant awarded.
