DonorSearch

DonorSearch helps you take the guesswork out of fundraising by providing deep insights into your donors' wealth and philanthropic history. You can screen your entire database to identify individuals with the greatest capacity and inclination to give, allowing your team to focus their energy on the most promising major gift prospects. The platform aggregates data from dozens of public and proprietary sources to give you a clear picture of a donor's previous giving to other organizations.

You can also use the platform to find new prospects through its vast database of philanthropic gifts and real estate records. By integrating these insights directly into your existing CRM, you keep your workflows centralized and your data actionable. Whether you are running a capital campaign or looking to grow your annual fund, these tools help you build more meaningful relationships with the right supporters.

Stardog

Stardog helps you break down data silos by creating a flexible knowledge graph layer over your existing infrastructure. Instead of moving data into a central warehouse, you can leave it where it lives—in SQL databases, NoSQL stores, or cloud apps—and query it as a single, unified source. This approach allows you to see relationships between data points that traditional systems often miss.

You can use the platform to power complex data discovery, fraud detection, and enterprise-wide search. It uses a semantic layer to ensure your data remains consistent and understandable across different teams. By automating the mapping of disparate data sources, you reduce the time spent on manual data preparation and can focus on gaining actual insights from your information.
