Major Gift Due Diligence: What Every Development Team Needs to Know

Due diligence is no longer a nice-to-have for nonprofit organizations accepting major gifts, it is a necessity. And yet, for many development teams, it remains one of the most underdeveloped parts of the fundraising process. 

That was the focus of our recent webinar, The Hidden Risk in Major Gifts: Building a Modern Due Diligence Strategy, where I had the opportunity to walk through what modern due diligence actually looks like, why it matters more now than it ever has, and how organizations of every size can build a program that protects their mission without slowing their momentum. 

What follows are the key takeaways from that conversation. 

Key takeaways

The UHNW population is growing, and so are the stakes. 

There are approximately 510,810 ultra-high-net-worth individuals globally today, each with a net worth of $30 million or more. Together, they account for $207 billion in philanthropic donations, equivalent to 36% of all individual giving. By 2030, that population is forecast to grow to nearly 700,000. The opportunity is significant, and so is the responsibility that comes with it. 

The risks of not doing diligence are broader than most organizations realize. 

Financial risk is the obvious one: accepting a gift you later have to return has real dollars-and-cents implications. But the reputational, legal, and mission alignment risks can be even more damaging. A donor whose source of wealth contradicts your organization’s values can cause donor fallout, media scrutiny, and long-term damage to your brand that far outweighs the value of the original gift. 

Due diligence is not one-size-fits-all. 

The level of diligence required scales with the size and profile of the gift. Smaller, known donors may require only a light review. Transformational gifts from high-profile or previously unknown individuals demand a fully enhanced due diligence process with collaboration across research, legal, development, and board leadership. The key is having a repeatable, scalable framework in place before you need it. 

The biggest challenge is doing more with less. 

When I asked our webinar audience what their greatest due diligence challenge was, the top answer was scaling due diligence with limited internal resources. That is consistent with what I hear from organizations every day. Campaign goals are not shrinking, but teams are. The solution includes repeatable workflows, clear thresholds, and the right external partners. 

AI has a role, but the human element remains non-negotiable. 

AI tools are increasingly useful for data aggregation and pattern recognition. But when it comes to contextual judgment, ethical decision-making, and the nuanced risk assessment required for major gift due diligence, human intelligence is still the standard, and that will not change anytime soon. 

The opportunity behind the risk

To understand why due diligence matters so much right now, it helps to start with the scale of the opportunity itself. There are approximately 510,810 ultra-high-net-worth individuals globally today, each with a net worth of $30 million or more. Together, they account for $207 billion in philanthropic donations, equivalent to 36% of all individual giving. That concentration of giving power in a relatively small population is precisely why major gifts carry such weight for development teams across nonprofits, universities, and healthcare organizations. 

Geographically, roughly half of that population, approximately 276,230 individuals, resides in North America, a figure that has grown by 5.8%. Asia and Europe represent the next largest cohorts, at 180,050 and 163,030 respectively, with growth rates of 6.9% and 5%. And by 2030, the global UHNW population is forecast to reach nearly 700,000 individuals. This population is growing. And with that expansion comes both greater opportunity and greater responsibility for the organizations seeking to engage it. 

Why due diligence matters more now than ever 

When I think about major gift due diligence, I frame it around a simple concept: safety and risk. Every decision we make involves weighing the two. A small gift from a well-known donor carries low risk and may require only a basic review. A transformational gift from someone new to your organization, with high public visibility and complex sources of wealth, demands an entirely different level of scrutiny. 

The problem is that too many organizations are still making these decisions reactively rather than proactively. They build or strengthen their due diligence programs after something has gone wrong, not before. 

The simple truth is that the landscape has changed. Philanthropy is increasingly global, donors are increasingly high-profile, and the public scrutiny of major gifts has never been more intense. The implications of getting it wrong are significant enough that no organization can afford to treat due diligence as a checkbox. 

The hidden risks organizations often miss 

Most development professionals understand the financial risk of accepting a gift they later have to return. But there are categories of risk that tend to slip through the cracks. 

• Reputational risk is harder to quantify but potentially more damaging. If a high-profile donor becomes associated with negative media coverage and your organization accepted their gift without proper vetting, the fallout extends beyond that individual. Other donors may pause or reconsider their giving. Prospective donors may look elsewhere. In the case of universities, prospective students and their families may make enrollment decisions based on how an institution handles these situations. 

• Mission alignment risk is perhaps the most overlooked. I worked with a client who accepted a large gift and discovered two years later that the donor had sourced their wealth from an industry that directly contradicted the organization’s stated mission around sustainability and climate change. The board required the gift to be returned. The reputational damage was significant. A proper due diligence process would have surfaced that misalignment before the gift was accepted. 

• Political affiliation risk is increasingly relevant. We are operating in a polarized environment, and donors on either side of the political spectrum can create complications for organizations that have not thought through where they stand on these issues. That does not mean avoiding donors with political affiliations, but it means understanding them and making informed decisions about alignment. 

What modern due diligence actually looks like 

There are two questions every organization needs to answer when building a due diligence program: when should diligence be triggered, and what should it actually evaluate? 

When should organizations perform due diligence: Due diligence should be triggered before any major solicitation, whenever a gift meets a predefined acceptance threshold, when dealing with high-profile prospects, and during campaign planning. The specific thresholds will vary by organization, but the principle is the same. The framework needs to exist before the gift arrives. 

What should organizations be evaluating as part of performing due diligence: The non-negotiables are source and legitimacy of wealth, negative media and significant litigation, sanctions list checks, and mission alignment. These are the areas where organizations most frequently encounter risk, and where the consequences of missing something are most severe. 

For organizations that are earlier in their due diligence journey, the goal should be simplicity first. Repeatable checklists, clear workflows, and defined thresholds are more valuable than a complex process that nobody follows consistently. You can always add sophistication over time. Start with something your team can actually execute. 

Scaling your due diligence program 

The approach to due diligence looks different depending on the size and resources of your organization, but the underlying principles are the same. 

• Smaller organizations: Smaller organizations should focus on prioritizing the highest-value prospects and building simple, repeatable processes that can be transferred easily when responsibilities shift. You do not need an elaborate program to do meaningful diligence. You need a clear starting point and the discipline to follow it consistently. 

• Mid-sized organizations: Mid-sized organizations benefit from formalizing their gift acceptance thresholds and incorporating third-party research partners into their workflows for higher-level gifts. The hybrid model, where internal teams handle initial research and external partners provide enhanced due diligence on transformational gifts, is the most common and often the most effective approach. 

• Enterprise organizations: Enterprise organizations typically have dedicated diligence resources and benefit most from cross-departmental collaboration. When a transformational gift is on the table, research, legal, development, and board leadership all need to be working from the same information and aligned on the decision. 

Across all three, the principle I keep coming back to is this: simple is scalable. Complex processes are difficult to execute, difficult to transfer, and difficult to sustain. If your due diligence program is so cumbersome that your team resists using it, it is not protecting you. 

Where Altrata fits in 

Data is the foundation of every due diligence decision, and not all data is created equal. 

At the base level, wealth screening gives you directionally correct information across a broad database, helping you prioritize who deserves a closer look. But for major and transformational gifts, you need something deeper. You need human-verified intelligence that gives you a complete picture of who this individual is: their net worth and liquidity, their career history, their board memberships, their philanthropic activity, their interests and values, and any red flags that warrant further investigation. 

That is what Altrata delivers. Our enhanced due diligence reports are built by a dedicated team whose sole focus is producing detailed, accurate, and objective assessments of individuals and entities. Each report includes a color-coded risk assessment covering sanctions exposure, source of wealth, litigation, and adverse media. Every flag comes with the detail behind it. We do not make the decision for you. We give you everything you need to make it with confidence. 

Altrata’s relationship mapping identifies how your existing network connects to prospective donors, turning cold outreach into warm introductions.

The organizations that protect their mission most effectively are not the ones that avoid risk. They are the ones that understand it clearly. Altrata is here to help make that possible.
