One LOI Per Year: Getting the James Graham Brown Letter of Interest Right Before October 15

Today’s competitive nonprofit market requires you to show more than a compelling mission when you pursue foundation support. You often have strong program ideas but lack a current, defensible way to explain what will change and how you will measure it. This is where a disciplined Letter of Interest (LOI) process becomes invaluable before the James Graham Brown Foundation’s final 2026 deadline.

For your Louisville Metro nonprofit, the central issue is not simply submitting on time. You have one LOI per calendar year, so you need to use that opportunity to present a focused, measurable, and credible case for support.

1. Know the Deadline and Rules

The James Graham Brown Foundation accepts LOIs on a rolling basis for its Louisville Responsive Community Grants. For the current cycle, the final LOI deadline is October 15, 2026. If you receive an invitation to submit a full application, you must submit it by December 1, 2026.

You should begin with the requirements listed on the James Graham Brown Foundation grants page. Your organization must be an established nonprofit located in the Louisville Metro area with an annual operating budget of at least $300,000. Organizations established within the last three years are typically ineligible. Individuals, political entities, and performing arts groups are also typically ineligible for this opportunity.

You also need CEO approval before submission. You will submit through the foundation’s online portal, using the new-organization LOI path or the established-organization LOI path, depending on your organization’s history with JGBF.

2. Treat One Shot Seriously

The one LOI per calendar year rule changes your preparation strategy. You cannot submit a half-formed concept in October and plan to improve the same request during another LOI window. Your next opportunity may arrive too late for your current program timeline.

Short applications can create a false sense of ease. Because an LOI may require fewer pages than a full proposal, you may be tempted to draft it quickly. The opposite is usually more accurate: brevity raises the bar for precision. You need to communicate the need, proposed response, expected outcome, organizational readiness, and measurement approach without leaving the reviewer to fill in the gaps.

For example, a broad statement about expanding access to services may describe a meaningful mission. It does not yet explain the specific change you intend to produce, the people who will experience it, or the evidence you will use to evaluate progress. Your single annual submission needs to answer those questions directly.

3. Make Measurement Specific

You can usually explain what your organization does and why the work matters. The more difficult task is writing one outcome sentence that states what will change, for whom, by how much, and by when.

That sentence should include a numeric target. It should also connect directly to the outcomes and impact that JGBF asks applicants to demonstrate. The foundation’s published guidance emphasizes significant outcomes, impact, and sustainability, not simply a list of activities.

For instance, “You will provide expanded services to local families” describes an activity. A stronger outcome statement identifies the population served, the intended improvement, the target level of change, and the period of performance. You can then connect that statement to the baseline data, milestones, and reporting process that will show whether progress is occurring.

Your LOI does not need to include every measure your organization tracks. It does need to show that you understand which measure matters most for the proposed project and that you can monitor it consistently.

4. Prepare Before Drafting

Before you open the application portal, assemble the measurement information that will support your LOI. You should have the following items ready:

• A one-sentence outcome statement with a numeric target

• The current baseline for that measure

• Evidence that you already track it through a dashboard, monthly report, or documented reporting cadence

• A realistic period of performance with milestones inside it

• A short explanation of who owns the data and reviews it

Your baseline matters because a target without a starting point is difficult to evaluate. If you cannot explain your current position, you may struggle to demonstrate whether the proposed project represents meaningful progress.

You should also verify that your program team and development team use the same definitions. For example, “participants served,” “engagement,” or “successful completion” can mean different things to different departments. A clear KPI definition prevents confusion in your LOI and gives your team a stronger foundation for a future full application.

A practical board and funder reporting system can help you organize the KPI dictionary, data workbook, scorecard, and funder reporting structure you need to support this work.

5. Use the September Close

The October 15 deadline makes your September month-end close especially important. If you receive a clean September close, you can use current information to confirm your baseline, review recent performance, and identify any data gaps before you draft.

Your month-end close should give you more than financial information. You should also be able to review program volume, participant outcomes, service quality, staffing capacity, and any other KPIs connected to your proposed project. When those numbers are assembled and reviewed monthly, you can write from evidence instead of memory.

By contrast, if your organization regularly scrambles to assemble monthly numbers, you may also scramble to support this LOI. A recurring reporting rhythm reduces that risk because your team already knows where the data lives, who checks it, and how leadership uses it.

Your September close does not need to answer every question in the application. It should give you a defensible starting point and enough visibility to determine whether your proposed outcome is realistic.

6. Follow a Practical Sequence

You can make the October deadline more manageable by dividing the work into a clear sequence:

• Days 1–3: Confirm your outcome statement and baseline.

• Days 4–6: Verify eligibility and confirm CEO approval timing.

• Days 7–9: Draft the LOI around the selected measure.

• Days 10–12: Complete internal review, check consistency, and resolve data questions.

• Submit several days early rather than waiting until October 15.

Your internal review should test whether the LOI makes one clear argument. You should confirm that the proposed activity connects to the outcome, that the outcome connects to your baseline, and that your organization can explain who will manage the data.

You should also review the submission for unnecessary breadth. If you describe multiple goals without identifying the primary result, the LOI may feel unfocused. A concise request with a clear measure can be more persuasive than a wide-ranging description of every service your organization provides.

Because the application is processed through an online portal, early submission gives you time to address login issues, incomplete fields, attachments, or approval delays. You should not make October 15 the day you discover a technical problem or realize that your CEO has not approved the request.

7. Check Eligibility First

Your eligibility review should happen before your team invests significant time in drafting. If your annual operating budget is below $300,000, your organization was established within the last three years, or you have already submitted an LOI during this calendar year, this may not be your cycle.

You should also confirm your location, organizational status, and program fit. Performing arts groups, individuals, and political entities are typically ineligible. Requests for routine operations or ongoing program costs may also require careful review against the foundation’s published criteria.

A timely eligibility decision protects your team’s capacity. If this opportunity does not fit, you can redirect your effort toward a funder whose requirements align with your organization, project, and current stage of development. That is a form of measurement discipline too: you are testing fit before investing resources.

You can use the official JGBF grants guidance as your starting point and contact the foundation through the information provided there if you need clarification about your situation.

Final Thoughts

The October 15, 2026 deadline is a hard stop, but the one-LOI rule is the more important planning constraint. You need a clear outcome statement, a current baseline, credible reporting evidence, CEO approval, and a realistic submission sequence before you enter the portal.

Your September close can give you the foundation for a stronger LOI. Your KPI definitions can make the request more precise. Your monthly reporting cadence can help you show that the proposed outcome is not only important but also measurable and manageable.

If you need to establish those pieces before your next LOI window, consider a Genesis Consulting Reporting Diagnostic. You can use the process to clarify your baseline, define your KPIs, and build a monthly reporting rhythm that supports board and funder conversations.

If you are preparing for the James Graham Brown Foundation deadline, start with the measure, not the narrative, and submit only when your organization can defend the result you are asking a funder to support.
