Foundations and private philanthropists often prioritize gifts with visible, attributable community impact. General operating support and internal technology investments can be harder to fund because their outcomes may be less immediate or apparent. More than anything, donors want to understand how their support, name, and legacy will create a tangible benefit for the communities an institution serves.
Capption provides a rare opportunity for private donors to improve your institution's experience for thousands of underserved guests. As a low-cost, high-impact accessibility layer, Capption solves severe equity barriers publicly in days or weeks instead of months or years. Donors can behold the real-life results of their gift the very same quarter they donated. You can guarantee the donor that 100% of their gift is going toward sustainable community access instead of back-office IT maintenance.
We've drafted the templates below targeting the mechanics and truisms of private giving throughout its two main sectors:
Strict, gatekeeper-focused Letters of Inquiry (LOIs) for foundations
Legacy-focused, scanner-friendly pitches for individual major donors.
Copy, paste, and edit as needed.
1. Foundation Letter of Inquiry (LOI)
Foundations use the LOI to filter thousands of requests and protect their team's time. Continue that respect: don't send an unsolicited full proposal, and don't attach unrequested brochures, photos, or full budgets.
A successful LOI is a concise 1.5 to 2 pages (800–1200 words) formatted as a professional business letter. Copy and modify this modular LOI to prove that your Capption rollout aligns with their goals for community equity and education.

Dear [Specific Program Officer or Board President Name]:
The [Museum Name] is seeking a partnership with the [Foundation Name] to radically expand our capacity for lifelong learning. We are requesting an initial grant of $[Amount] to launch the [Initiative Name or Inclusive Discovery Initiative]. This project will reduce the physical, social, and linguistic barriers that currently impede our visitors' curiosity and exclude underserved populations from our exhibition spaces. This request directly aligns with the [Foundation Name]'s stated priority to [insert the foundation's specific mission statement, e.g., "support equitable education and community health in our region"].
Since our founding in [Year], [Museum Name] has served [City/Region] by [Brief statement of core services/programs]. This initiative will be led by our [Title], [Name], who brings [X] years of experience successfully managing and executing inclusive community programming.
While we proudly welcome [Number] visitors annually, our exhibition spaces inadvertently favor a narrow demographic: fully-sighted, native-English speakers. In the United States, 1 in 5 people have learning and thinking differences that can prevent them from fully experiencing our exhibitions. The cost of doing nothing is severe: access barriers create stress, and stress crushes engagement. In our region alone, [Insert local demographic stat, e.g., X% of residents] speak English as a second language, while our aging population increasingly battles minimum focal lengths and low light to read traditional placards. Legacy digital solutions like expensive custom apps, management-hungry webpages, or isolating audio guides only add friction to the visitor experience.
To solve this, we will partner with local community groups including [Partner 1] and [Partner 2] to implement Capption, a US-made assistive technology platform. Capption replaces the distracting friction of heavyweight apps with an invisible digital bridge. With a single tap of their smartphone on discreet NFC placards, visitors instantly receive perfectly formatted multimedia context. Capption automatically translates our curator's text into 136 languages and natively inherits the visitor’s pre-established accessibility settings (including text size, screen reader preferences, and hyperlegible fonts). Capption makes exhibit content portable, personal, and persistent. We will measure the effectiveness of this rollout through Capption's ongoing quantitative usage analytics and a post-installation qualitative accessibility audit, ensuring continuous alignment with our shared equity goals.
The total cost to launch this initiative is $[Total Project Cost]. We have already secured $[Amount] in leveraged commitments from [Other Source/Internal Funds]. We are requesting a grant of $[Amount] from the [Foundation Name] to cover the implementation and Year 1 software licensing. To ensure long-term sustainability, our Board has committed to absorbing Capption's modest, fixed annual software fee into our standard operating budget starting in Year 2, guaranteeing your grant funds the launch of sustainable community infrastructure, not a temporary pilot.
We would welcome the opportunity to submit a full proposal with a detailed schedule of completion, financial statements, and letters of support from our partners. Thank you for your time and your continued commitment to [City/Region].
Sincerely,
[Your Signature]

2. Major donor pitch
When pitching high-net-worth individuals, the conversation shifts from bureaucratic alignment to personal legacy and rapid impact. Major donor letters must be highly personalized and laid out for people who skim before they read. Center this letter entirely on the donor ("you"), focus on human outcomes over technology, and format for the six elements the eye naturally tracks: The donor's name, margin notes, bolding, the signature, the printed name, and of course, the P.S.
The legacy and impact narrative
[Date]
[Donor Name]
[Donor Address]
Dear [Donor Name],
I know that you are deeply passionate about making the arts accessible to everyone in our community. You've seen firsthand how transformative a visit to [Museum Name] can be.
But right now, hidden blockers like low vision, learning differences, and language barriers prevent thousands of our neighbors and visitors from fully experiencing the art you love. Access barriers create stress, and stress crushes engagement.
We are launching a new initiative to reduce these barriers quickly, and we want you to be the driving force behind it.
By providing a leadership gift of $[Specific Amount], you will instantly transform our museum into a more accessible, multilingual space. We are implementing an invisible digital prosthesis that allows any visitor, with a single tap of their own smartphone, to instantly receive our exhibit content in a format they can easily read and understand.
Because of your generosity, a senior citizen will be able to read exhibit text without squinting through glare. Because of you, a non-native speaker will instantly receive our curator's story translated into their preferred language. Because this technology requires no complex visitor app onboarding and no arduous institutional maintenance, your gift delivers immediate impact.
We'd be honored to name this rollout the "[Donor Last Name] Fund for [Initiative Name or Inclusive Discovery]." Furthermore, I will personally send you a quarterly impact report detailing the number of visitors reached and the accessibility outcomes supported by your gift, demonstrating real return on your investment.
Thank you for your continued leadership and belief in our community. I'll call you [Day/Time] to discuss how we can make this vision a reality together.
With deepest gratitude,
[Your Handwritten Signature]
[Your Printed Name]
[Your Title]
P.S. Your gift of $[Amount] will help remove the barriers that stymie our visitors' curiosity, granting thousands of families the autonomy and comprehension they deserve. I look forward to speaking with you soon.
(Note for Development officers: Handwrite a brief, personal note in the margin of the printed letter, such as "Great chatting about 'X' at the gala last month!")
3. Budgeting and 1:1 match synergy
One of the most powerful ways to secure a private donation is the leverage pitch: using a private major gift to unlock further state or federal funds. Individual donors and foundation boards love knowing that their money is working twice as hard.
The federal match play
If you apply for an IMLS Inspire Grant for a Large Project ($25,001.00–$75,000.00), the federal government explicitly requires a 1:1 institutional cash match.
Pitching this to a private donor:
"We're applying for a $30,000.00 federal grant to modernize our community accessibility, but the government requires us to match it dollar-for-dollar. If you can provide a $30,000.00 leadership gift, you won't just be funding this project, you'll unlock an additional $30,000.00 in federal funds for our museum, doubling the impact of your philanthropy."
Budgeting for sustainability
When submitting a full budget to a private foundation, structure it as a capacity building grant.
Your ask: Request funds to cover the Year 1 Capption software license, the physical NFC placards, and the Capption Professional Services onboarding fee.
The guarantee: Private foundations hate funding endless operating costs. State clearly in your budget narrative that by Year 2, the museum will absorb Capption's low, fixed annual SaaS fee into the standard operating budget. This demonstrates to the foundation that they are funding the launch of sustainable community infrastructure, not a temporary pilot. Contact us for exact pricing for your budget sheet.
4. Proof of impact quotes and citations
Private donors want to know that their money is funding proven, reliable infrastructure with measurable outcomes. Use these direct quotes from our museum partners in your proposals to demonstrate Capption's immediate speed-to-value and community impact:
Measure personal impact: "Of the hundreds of Capption users in our pilot gallery, 20% used accessibility features, 15% read labels in Spanish, and another 15% used languages we never saw coming." —Head of Audience Project Management at Mia
Simplify assistance: "Capption adds new disability resources and replaces translated materials, audio guides, self-guided tour sheets, and even works outside!" —Director of Public Engagement & Learning at Weisman Art Museum
Minimize translation guesswork and cost: "We wasted $50,000 translating an exhibit that left 2 months later...and we didn't pick the right languages. Capption solves this forever." —Head of Engagement at Walker Art Center
Clean up displays: "I was worried about labels for ~230 clay pots in one room, with busy text and ugly QRs, but this looks incredible and delivers infinitely more." —Executive Director at White Bear Center for the Arts
Say "yes" to people who need help now: "Anyone—needing any help—can show up any time. Unless they needed seating or spoke Spanish, we couldn't help. We had nothing until Capption." —Director of Operations at the American Swedish Institute
These and other case studies will support any impact claim you'd like to make:
Arts education and community access: White Bear Center for the Arts (WBCA) expanded their community accessibility without overburdening their small team
Preserving historic spaces: The American Swedish Institute (ASI) added a digital accessibility layer without impacting their historic layer
Speed to value: How the Putnam Museum deployed 37 accessible exhibits in 50 minutes
