Plinth is a portfolio insights layer for grantmakers. It sits on top of the system you already use and does the analysis your grants system cannot. Plinth reads the reports, notes and check-ins already in your system and turns them into a clear picture of how your funding moves and what it is achieving. Grantees who have gone quiet. Where your money lands and where it does not. Who needs your attention this week. No migration, no new forms, and nothing extra asked of your grantees. Plinth also offers a full end to end grant management system for foundations that want to replace what they have.
