Nonprofit Sustainability Initiative San Diego

Investing in Nonprofit Impact

The Nonprofit Sustainability Initiative (NSI) San Diego is a pooled fund fiscally sponsored by Catalyst of San Diego & Imperial Counties inviting applications from September 1, 2026 onward to support non-profit organizations pursuing formal sustained collaboration partnerships that increase mission impact, organizational effectiveness, and long-term sustainability.

Strengthening Nonprofits Through Collaboration

Collaboration is one of the most powerful paths towards sustained impact, and yet it is often one of the most under-resourced. Many nonprofits lack access to the flexible, discretionary funding required to navigate complex transitions while continuing to deliver on their missions.

NSI San Diego helps close that gap by supporting a range of collaboration models, including:

• Jointly managed programs
• Back-office consolidations
• Shared ventures
• Full-scale mergers.

With the right support in place, organizations can reduce duplicative work, strengthen internal operations, and focus more of their time and energy where it matters most: serving their communities.

Responding to a Changing Nonprofit Landscape

Nonprofits today are facing increasingly destabilizing conditions that threaten their long-term viability. Federal funding cuts, heightened scrutiny, and shifting policy environments have changed what risk looks like and how quickly it can compound. The pace of these challenges means organizations are losing capacity faster than it can be rebuilt.

NSI San Diego responds to these challenges by investing in the kinds of structural supports that help nonprofits adapt, stabilize, and continue serving communities.

Exploratory Grants support two or more organizations that are ready to engage in structured discussions regarding a potential strategic partnership.

Organizations receiving Exploratory Grant funding are not committing to a specific outcome. Rather, they are committing to participate in a good-faith process of exploration, due diligence, and negotiation to determine whether a partnership would advance their missions and better serve their communities.

• Potential activities may include:
• Strategic assessment and readiness discussions
• Facilitation and negotiation support
• Organizational due diligence
• Governance and leadership conversations
• Financial and operational analysis
• Exploration of partnership models

Exploratory Grants typically range from $20,000–$40,000.

Funds are intended primarily for third-party consultants and technical assistance providers supporting the exploratory process.
