$650 · 4 weeks · 30 prospects
Prove adult chess players will deposit $100 toward a $480 attested coaching block for an income-qualified kid, for $650 in 4 weeks.
Riskiest assumption · Adult tournament players and chess parents will put money down today - $100 toward a $480 season block - for an income-qualified improving kid they cannot name, with lessons released only on coach attestation and US Chess rating verification, before any tax credit exists.
1Focus group: who and where
Adult US Chess members who play rated weekend tournaments or already pay $50-100 a lesson for their own kids' coaching, plus the small-dollar donors on one state chess association's existing scholarship-fund list - people deciding their fall chess spending and giving right now.
where to find 30 · Two US Chess-affiliated clubs in one metro, found through the uschess.org affiliate directory and pitched in person on club night; one Continental Chess Association weekend open in the same metro, where 150-300 rated adults gather; the partner state association's scholarship-donor email list; r/chess and the clubs' Discords for the landing page.
2Sell first, build later
A season coaching block for one income-qualified improving kid: 12 lessons with a background-checked coach starting within 30 days of the cohort seating, released one lesson at a time on coach attestation and confirmed against the kid's US Chess rating record, with an anonymized cohort progress report to you after every posted crosstable.
the ask · $480 per season block ($40 per lesson); $100 deposit now, balance due when the cohort seats
a real yes · A real yes is $100 moved into the association's scholarship fund earmarked for the cohort; 'chess needs this' at the board, unfunded pledge forms and offers to volunteer are not.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Deposit pre-sale at the boards
$300 · 14 days
Print a one-page flyer with a checkout QR and pitch 30 adults face to face across two club nights and one CCA open: a $100 refundable deposit toward a $480 season block (12 lessons at $40) for one income-qualified improving kid, lessons released only on coach attestation plus a US Chess rating check. One founder works the skittles room between rounds with the outreach script.
keep going if · 8 of 30 adults pitched put down $100
2. State association MOU
$100 · 21 days
Pitch the volunteer boards of 4 state chess associations, contacts pulled from uschess.org state affiliate pages, to run the pilot through their existing 501(c)(3) scholarship fund with a dated decision on 2027 SGO conversion. Deliver a two-page program design and a draft MOU on the first call.
keep going if · 1 signed MOU naming a 20-kid pilot cohort and a January 2027 start
3. Coach opt-in with checks
$250 · 14 days
Recruit 20 coaches from lichess.org and Chess.com coach listings plus the association's coach network: $40 per lesson paid on one-tap attestation, background check required before the first session. Run checks only on coaches who opt in.
keep going if · 10 of 20 coaches opt in and 8 start the background check
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.
$100
per prospect, refundable
how · A $100 refundable deposit paid into the partner state association's existing 501(c)(3) scholarship fund through the association's own donation checkout, earmarked for the pilot cohort - chosen because the association is already registered to take charitable money, so the donor gets a normal deduction today with no new legal surface. set up: Stripe Checkout ↗
what it reserves · One sponsored-kid slot in the first 20-kid cohort, the $40-per-lesson rate locked for the full season, and the donor's cohort progress feed.
refund · Refunded in full by the association if the cohort has not seated within 60 days of the pledge.
target · 8 deposits from 30 face-to-face asks within 21 days
before taking money · SGO tax-credit rules are not settled, so run every dollar through the association's existing 501(c)(3), market the deposit as an ordinary charitable gift, and make no 2027 tax-credit claims until IRS guidance confirms coaching qualifies and the state has opted in.
Go: build it if
8 of 30 prospects deposit $100, 1 state association signs the MOU with a January 2027 start, and 10 coaches accept attestation-gated pay - convert deposits to full blocks and build.
Kill: stop if
Fewer than 4 deposits from 30 face-to-face asks, no association MOU after 4 board pitches, or fewer than 5 coaches accept attestation-gated pay.

outreach message
You pay for lessons or weekend entries every month, so you know what real coaching does for a rating. I'm running a pilot with the state association's scholarship fund: your $100 deposit starts a 12-lesson block for an income-qualified kid who is climbing, and each lesson releases only when a background-checked coach attests it and US Chess confirms the rating record. 20 kids in the first cohort, refunded if we don't seat it in 60 days. Got 20 minutes after your round to see the one-pager?

The concept in full
- What
- Rookline runs SGO-compliant chess scholarship programs: donors pledge coaching blocks that release per delivered lesson when a background-checked coach attests the session and US Chess rating data confirms the kid is climbing. Selection weighs rating trajectory and tournament attendance for income-qualified families, not absolute rating, so improving kids from cheap park programs beat already-coached suburban experts. The kid gets a private rating graph plus a coaching-hours-earned meter; donors see anonymized cohort progress the day a crosstable posts.
- Grounded in (2025-2026 signals)
- The One Big Beautiful Bill Act (July 4, 2025) created the $1,700 SGO credit; on June 8, 2026 the IRS reported 27 states had elected in (IR-2026-76). Open Badges 3.0 lets a chess rating milestone become a W3C Verifiable Credential the kid owns, with 1EdTech expecting mass adoption in 2025-26.
- What it rides
- 'Federal scholarship tax credit from 2027, 27 states in': Rookline packages chess coaching funds as Scholarship Granting Organization programs so a donor's dollar comes back as the $1,700 credit.
- Why now
- The credit is claimable from January 1, 2027 and 27 states including Texas, Florida and Ohio opted in by June 8, 2026; SGOs need turnkey merit-plus-need programs before the first credit year opens, and chess ratings are the cleanest objective record in youth talent.
- Wedge: first customer and entry point
- One state chess association's existing scholarship fund: convert it to an SGO-qualified program with 20 coaches through background checks and one-tap session attestation before the 2027 filing season.
- Closest real companies, as the generator saw them
- trophi.ai builds an AI coach for any skill; Rookline funds human coaches against verified results instead of replacing them. Sertifier issues credentials but moves no money.
- Main risk
- IRS guidance narrows qualifying SGO expenses to tuition and excludes standalone coaching, stranding the program design.
