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.

Target Constituency: We support non-profit organizations serving middle school students who face gaps in comprehensive high school readiness. These organizations implement innovative programming that creates challenging yet nurturing environments—preparing students for achievement while inspiring them to become engaged, confident citizens ready to contribute to their communities.

Health & Wellness

Goal: Advance children’s health and well-being by supporting nonprofits that strengthen social conditions, empower youth, and build healthier environments in marginalized communities.

Target Constituency: Nonprofits whose work strengthens social determinants of health for children in marginalized communities.

Play & Recreation

Goal: Advance children’s social-emotional development and physical well-being by supporting nonprofits that create inclusive play-based programming, competitive sports opportunities, and outdoor recreational experiences in under-resourced communities.

Target Constituency: Non-profits whose work promotes access to quality recreational programming for children ages 6-18 in under-resourced communities.

For all grants, the organization’s mission and scope must align with the Foundation’s mission. For the latter, these grants can be either unrestricted or restricted to a particular program or project. The type of grant and what it is used for will dictate the goals and objectives to be met.
