What if your nonprofit’s next great donor is already hiding in plain sight?
Before you call in the detectives, dust off the magnifying glass, or start searching for footprints, let me explain.
I’m talking about donor research.
Good fundraising has always involved a little detective work. The best fundraisers are curious. They ask questions. They notice connections. They follow clues. And they don’t stop at the first piece of information they find.
In other words, they’re a little bit Nancy Drew and a little bit true-crime investigator.
Don’t worry—we’re not talking about interrogating donors or creating a wall covered in red string.
We’re talking about using information you already have—and information that is publicly available—to better understand your donors, identify potential prospects, and uncover relationships that may otherwise go unnoticed.
Nancy Drew Had a System. So Should You.
Think about Nancy Drew.
She didn’t simply stumble across a mystery and immediately announce, “I know who did it!”
She gathered clues.
She asked questions.
She paid attention to details other people overlooked.
She connected seemingly unrelated pieces of information.
And most importantly, she was curious.
That’s exactly the mindset a nonprofit can bring to its donor database.
Imagine your database contains:
- Jane Smith — annual donor: $500
- Robert Jones — annual donor: $1,000
- ABC Company — annual sponsor: $2,500
- Mary Williams — annual donor: $250
At first glance, these are simply names and dollar amounts.
But what happens when you start asking questions?
Who are these people?
Where do they work?
Are they connected to a business?
Do they serve on a corporate board?
Are they involved with other nonprofits?
Have they attended your events?
Are they volunteers?
Do they have a history of supporting organizations like yours?
Are two donors connected to the same company or community organization?
Suddenly, your database isn’t just a list of names.
It’s a collection of clues.
Clue #1: Look Beyond the Donation
One of the biggest mistakes small nonprofits make is looking at a donor only through the lens of their gift.
A $250 donor is not necessarily a “small donor.”
That $250 may be the beginning of a much larger relationship.
Suppose you discover that your $250 donor is:
- The owner of a successful local business
- A member of a community foundation
- A board member of another nonprofit
- An employee of a company with a matching-gift program
- A longtime volunteer in your community
- Connected to someone already serving on your board
That changes the conversation.
The question is no longer:
“How do we get this person to give us more money?”
Instead, you’re asking:
“What else can we learn about this person’s interests and connection to our mission?”
That’s a much better fundraising question.
Clue #2: Follow the Connections
True-crime investigators are famous for building timelines and identifying relationships.
Fundraisers can do something similar.
Let’s say your nonprofit receives a $1,000 gift from Susan.
Susan works for XYZ Corporation.
You discover that XYZ Corporation has a community giving program.
Then you discover Susan volunteers with a local civic organization.
And one of your board members happens to serve on the same committee.
Now you have several potential points of connection.
You might have:
Donor → Employer → Corporate Giving Program → Community Connection → Board Relationship
That’s not a coincidence you want to overlook.
Your donor database should help you identify these connections.
Clue #3: Don’t Ignore the “Cold Case” Donor
Every nonprofit has them.
The donor who gave $1,000 three years ago and then disappeared.
The longtime supporter who hasn’t donated since 2022.
The person who made a generous gift but never appears in your current fundraising conversations.
Don’t automatically write them off.
Instead, reopen the case.
Ask:
What happened?
Did they move?
Did their employer change?
Did their interests change?
Did your nonprofit stop communicating with them?
Did you fail to thank them properly?
Did their giving pattern change?
Did they attend an event that you didn’t record?
A lapsed donor isn’t necessarily a lost donor.
Sometimes they’re simply a donor whose story you stopped following.
Clue #4: Build a Donor Profile
Nancy Drew wouldn’t investigate a mystery without taking notes.
Your nonprofit shouldn’t conduct donor research without documenting what you discover.
For your key donors and prospects, consider creating a simple profile that includes:
Basic Information
- Name
- Preferred contact information
- Employer/business
- Location
Relationship to Your Organization
- First gift
- Most recent gift
- Lifetime giving
- Event attendance
- Volunteer history
- Board connections
Interests
- Programs supported
- Areas of interest
- Community involvement
- Other organizations they publicly support
Potential Opportunities
- Corporate giving
- Matching gifts
- Sponsorship
- Major gift conversation
- Volunteer leadership
- Board service
- Planned giving
Now your fundraiser has something much more valuable than a name.
You have context.
Clue #5: Look for the Hidden Donor
Here’s where things get particularly interesting.
Your nonprofit may already have potential donors in its database who have never made a significant gift.
Think about:
Volunteers.
A volunteer who gives $25 may have a much deeper connection to your organization than someone who writes a $250 check once a year.
Event attendees.
Someone who attends your annual gala, concert, museum event, lecture, or community festival every year may be demonstrating significant interest—even if their donations are modest.
Former board members.
Past board members can become some of your most valuable ambassadors and donors.
Parents and families.
For schools, museums, zoos, arts organizations, and youth-serving nonprofits, family relationships can create long-term giving opportunities.
Corporate connections.
Someone who works for a local company may be the bridge between your nonprofit and a corporate sponsorship opportunity.
The clue isn’t always the size of the gift.
Sometimes the relationship is the clue.
What Would a True-Crime Sleuth Do?
They’d probably make a list.
So let’s make one for your nonprofit.
The Nonprofit Donor Sleuth Checklist
When researching a donor or prospect, ask:
1. Who are they?
What do you know beyond their name and address?
2. What is their connection to your organization?
Donor? Volunteer? Event attendee? Parent? Former board member?
3. What do they care about?
Look for publicly available evidence of interests related to your mission.
4. Who do they know?
Are there legitimate, documented connections to your board, staff, volunteers, businesses, foundations, or community leaders?
5. Where do they work?
Could their employer offer matching gifts, sponsorships, volunteer grants, or other corporate support?
6. What is their giving history?
Look at frequency, amount, program preference, and changes over time.
7. What clues have you overlooked?
Sometimes the most important information is buried in an old event list, volunteer spreadsheet, acknowledgment letter, or board report.
Your Database May Be Full of Clues
Here’s the part I wish more small nonprofits understood:
Your database is not just an accounting system.
It’s a relationship-management tool.
Unfortunately, many organizations use their donor database primarily to answer:
“Who gave us money?”
A sophisticated fundraising operation asks:
“What can we learn about our relationships?”
That’s a very different question.
Your database might tell you that John donated $500.
Your fundraising research might tell you that John has volunteered for five years, works for a company with a corporate foundation, attends every annual event, and has introduced two other donors to your organization.
Now you’ve got a story.
And stories create opportunities for better fundraising conversations.
But Let’s Keep the Magnifying Glass Ethical
There’s an important distinction between research and creeping people out.
Good donor research should rely on appropriate information, particularly information your organization already has or information that is legitimately and publicly available.
You don’t need to know everything about someone.
You need to know enough to understand their relationship with your mission.
The goal isn’t:
“What can I find out about this person?”
The goal is:
“How can I better understand this person’s connection to our organization so we can build a stronger relationship?”
That’s the difference between investigation and stewardship.
The Final Mystery: Who Is Your Next Donor?
The answer might be someone you’ve never heard of.
But it might also be someone already sitting in your database.
Maybe it’s the $100 donor who has been giving for seven years.
Maybe it’s the volunteer who knows everyone in town.
Maybe it’s the former board member who still attends every event.
Maybe it’s the employee of a company you’ve been trying to approach for years.
Maybe it’s the person who gave $5,000 five years ago and simply hasn’t heard from you lately.
You won’t know until you start looking.
So open your database.
Pick 25 names.
Put on your metaphorical trench coat.
Grab your magnifying glass.
Start asking questions.
Look for connections.
Follow the clues.
And remember the most important rule of fundraising detective work:
Don’t just look for money. Look for relationships.
Because the best donor prospect may not be hiding somewhere out there.
They may already be hiding in plain sight.
