Cadenza
Community foundation software that pays music teachers per attested lesson from pooled town funds
Cadenza gives community foundations a pooled instrumental-music fund: local donors give small deductible gifts, and the foundation pays vetted private teachers per lesson only after the teacher's one-tap attestation lands.

$700 · 4 weeks · 15 prospects
For $700 and four weeks, prove a community foundation will pay for per-lesson payment rails this giving season instead of renewing the annual block grant.
Riskiest assumption · A community foundation executive director will pay this quarter to route donor money through per-lesson attestation rails rather than renew the annual block grant to the school music program, which is the exact slow-mover risk the card names.
1Focus group: who and where
The executive director or program officer at a community foundation with $10M-$200M in assets in a town of 30,000-300,000, who is right now planning year-end giving campaigns around the new 2026 non-itemizer deduction and re-approving the same annual block grant to the school music program with no idea which kids it reaches.
where to find 15 · The Community Foundations National Standards accredited list at cfstandards.org (a directory of 500+ accredited foundations with named staff); state philanthropy associations with community-foundation peer groups, such as Indiana Philanthropy Alliance's GIFT program and Philanthropy Ohio (communities where small-foundation EDs actually talk); the Council on Foundations' community foundation membership and its fall convenings (event and channel). Pull 25 mid-size foundations across two or three states in two days.
2Sell first, build later
A live pooled music-lesson fund before year-end giving: 30 kid seats with income screening and audition-record criteria, 10 background-checked local teachers paid per attested lesson, and a Q1 2027 anonymized donor report; fund live by November 15, 2026.
the ask · $1,500 pilot fee covering setup and software through June 2027, then $400 per month
a real yes · A real yes is the $1,500 invoice paid or a board-signed pilot agreement with the November 15 launch date. A program officer's enthusiasm, an offer to 'discuss it at the spring board meeting', an unpaid trial inside the existing grant, or an intro to the band director is not a yes.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Fifteen block-grant replacement calls
$300 · 14 days
Build a list of 25 accredited foundations from cfstandards.org and the state association member rolls, email the ED directly, and book 15 twenty-minute calls. Ask how they fund youth music today, what they know about where the block grant lands, and whether they would route a donor fund through per-lesson payment; end every call by naming the $1,500 pilot. One founder runs all calls.
keep going if · 5 of 15 EDs say per-lesson payment would replace or sit beside the block grant and book a pilot scoping call
2. Priced pilot prospectus
$250 · 21 days
Send every call a two-page prospectus with the card's numbers: a 30-kid fund, 10 background-checked teachers, one-tap attestation, anonymized donor report, live by November 15, $1,500 pilot fee through June 2027 then $400 per month. Include a mocked donor report page. Ask for a signed pilot agreement and the invoice.
keep going if · 2 of 15 foundations pay the $1,500 pilot invoice or return a board-signed agreement with a November start
3. Teacher-side supply check
$150 · 14 days
Through the local Music Teachers National Association affiliate in one pilot town, call 10 private instrumental teachers. Offer their normal hourly rate paid weekly by the foundation, contingent on a one-tap attestation after each lesson and a background check. Count who accepts the terms in writing.
keep going if · 8 of 10 teachers accept per-lesson attested payment terms in writing
4Collect a deposit up front
Tesla took $1,000 refundable reservations for the Model 3 and $100 for the Cybertruck before building either: the deposit is the measurement, not the revenue.
$1,500
per prospect, refundable
how · A paid design-partner pilot invoiced up front: the foundation ED signs a two-page pilot agreement and pays a $1,500 invoice, the normal way foundations already pay software vendors like Foundant. No payment link needed; foundations pay invoices, not checkouts. set up: Stripe Payment Links ↗
what it reserves · One of two founding pilot slots, the November 15 launch date, and the $400 per month price locked through 2027
refund · Refunded in full if the fund is not live by December 1, 2026, or on request any time before the setup call.
target · 2 paid pilots from 15 ED conversations within 30 days
before taking money · Donor money and child data are regulated: the foundation must hold and disburse all charitable funds itself, and collect no child-identifying data in the product until counsel signs off on COPPA handling.
Go: build it if
2 foundations pay the $1,500 pilot fee and 8 of 10 teachers accept per-lesson terms within 4 weeks: build the attestation and reporting flow for the November launch.
Kill: stop if
0 paid pilots and fewer than 3 of 15 EDs willing to scope after all calls, or fewer than half the teachers accept attested per-lesson payment: foundations will keep writing block grants, stop.

outreach message
You probably fund youth music with one annual grant to the school program and hope it reaches the kids who actually practice. I'm building Cadenza: a pooled lesson fund your donors give into under the new 2026 deduction for non-itemizers, which pays vetted local teachers per attested lesson, with income screening and an anonymized town-level donor report. I'm signing two foundations for a $1,500 pilot that goes live before year-end giving. Do you have 20 minutes this week to see whether your town fits?
landing page
Your town's music fund, paying teachers per lesson delivered. $1,500 pilot: a 30-kid fund live by November 15, software included through June 2027. Book a scoping call and reserve one of two founding pilot slots.
deposit terms
The $1,500 pilot fee reserves one of two founding slots and covers setup plus software through June 2027, with $400 per month locked after that. It is refunded in full if your fund is not live by December 1, 2026, or on request before the setup call. Your foundation holds and disburses all donor money; Cadenza never touches it.

The concept in full
- What
- Cadenza gives community foundations a pooled instrumental-music fund: local donors give small deductible gifts, and the foundation pays vetted private teachers per lesson only after the teacher's one-tap attestation lands. Kids qualify through juried festival results, recital records and practice streaks combined with income screening, so seats go to committed low-income players, not families who already buy lessons. The kid keeps a practice-streak and repertoire log; donors see town-level progress with no named minors, per COPPA.
- Grounded in (2025-2026 signals)
- The Tax Foundation notes standard-deduction filers can deduct up to $1,000 cash ($2,000 joint) from tax year 2026. Aspen Institute's State of Play 2025 shows the participation gap between under-$25,000 and over-$100,000 homes reached 20.2 points by 2024, the same affordability wall music lessons face.
- What it rides
- 'Universal charitable deduction from 2026': small local gifts of $500 to the foundation's music fund become deductible for the 86% of taxpayers who take the standard deduction.
- Why now
- Tax year 2026 is the first in which roughly 86% of taxpayers get a deduction for small cash gifts, which is exactly the giving size a town music fund runs on; foundations have no per-session payment tooling to absorb it.
- Wedge: first customer and entry point
- One community foundation in a mid-size town: stand up a 30-kid fund with 10 background-checked teachers, attestation on the teacher's phone, and a quarterly anonymized donor report.
- Closest real companies, as the generator saw them
- none tracked
- Main risk
- Community foundations move slowly and may keep writing annual block grants to the school band instead of adopting per-session rails.
