Building stronger foundations for community impact
We provide fiscal sponsorship, grant management, and financial infrastructure so mission-driven organizations can focus on what matters most.
Our Mission
We believe great ideas deserve great infrastructure.
Granite City Foundation exists to remove the barriers between ambitious social impact work and the financial, legal, and operational structures needed to bring it to life. We provide 501(c)(3) fiscal sponsorship, sub-account banking, and real-time financial tools so our partners can move at the speed of change.
What We Offer
Three pillars of support
A modern approach to fiscal sponsorship — designed for speed, transparency, and real financial control.
Fiscal Sponsorship
Access 501(c)(3) tax-exempt status without forming your own nonprofit. We provide the legal umbrella, compliance oversight, and back-office support — you keep full creative and programmatic control.
Apply Now →Sub-Account Banking
Every sponsored project gets its own Mercury sub-account with real-time balance visibility, dedicated account numbers, and full transaction history. Your funds, your clarity.
View Portal →Card Issuance
Issue virtual and physical debit cards to your team directly through the Grantee Portal. Set spending limits, pause or cancel in real time — all powered by Mercury's secure banking infrastructure.

Your finances, transparent and in real time
Every grantee and fiscally sponsored organization gets access to a secure portal connected to their Mercury sub-account.
Real-Time Account Balance
View your current balance, pending transactions, and full ledger history — synced directly from your Mercury sub-account via API.
Issue & Manage Cards
Create virtual or physical debit cards for your team. Set per-card spend limits, freeze or close cards instantly — all from one dashboard.
Transaction Tracking
Every dollar is categorized and logged. Export reports for your board, funders, or grant compliance — always audit-ready.
Mercury API Integration
All financial data flows through Mercury's banking API — bank-grade security, real-time webhooks, and seamless sub-account mapping.
