The Hidden Engine Behind Collaborative Philanthropy: Fiscal Sponsors

Aug 1, 2025

Fiscal sponsors provide operational infrastructure for funder collaboratives to accelerate social change.

In recent years, collaborative funds have emerged as one of the most promising vehicles for advancing equity, justice, and systems change. A landscape scan of this fast-growing field by Bridgespan noted 35% of collaborative funds are fiscally sponsored or hosted collaborations. For example, Wildseeds Fund - a collaborative fund in Kansas that aims to protect food and agricultural systems – uses a fiscal sponsor to manage their collective funding operation. According to a 2024 report by Ganguli Associates funder collaboratives now deploy between $4–7 billion annually with more than 400 active funds operating globally. Yet, as the report makes clear, the success of these efforts hinges not just on pooled capital—but on the infrastructure that supports it.

The Infrastructure Gap

Ganguli’s report, Strengthening and Supporting the Enabling Infrastructure for Collaborative Funds, identifies a critical blind spot: while funders are increasingly eager to collaborate, many underestimate the operational complexity of doing so. From grant administration and legal compliance to financial reporting and HR, collaborative funds require a robust back-end to function effectively.

Yet, many collaboratives are launched without a clear plan for how this infrastructure will be built or sustained. The result? Delays, inefficiencies, and burnout among the very leaders these funds aim to empower.

Fiscal Sponsors: The Unsung Heros

This is where fiscal sponsors like Evergreen Social Impact (ESI) come in. As a nonprofit dedicated to providing shared infrastructure for mission-driven initiatives, fiscal sponsors can help collaborative funds:

  • Launch quickly without waiting for IRS 501(c)(3) status
  • Manage grants and donor funds with full compliance and transparency
  • Support community-led governance through participatory grantmaking models

In short, sponsors provide the enabling infrastructure that Ganguli’s report calls for—so funders and community leaders can focus on strategy and impact, not administration.

A Call to Action for Funders

The Ganguli report urges funders to invest not only in the “what” of collaboratives, but in the “how”. That means:

  • Budgeting for infrastructure from the start
  • Partnering with experienced fiscal sponsors
  • Recognizing that operational support is not overhead—it’s mission-critical
