Test it before you build it

$600 · 4 weeks · 15 prospects

For $600 and 4 weeks, prove club program directors will prepay a $450 season because their spreadsheet misses dedicated kids whose payments lapse before they quit.

Riskiest assumption · A club program director tracking twenty families in a spreadsheet will pay for software because that spreadsheet demonstrably misses dedicated kids whose payments lapse before they quietly quit.

1Focus group: who and where

The junior program director or head coach at a US sailing or rowing club with 20-150 juniors and an existing, often informal, scholarship fund - staring at fall re-registration this month and guessing which families will quietly not re-up.

where to find 15 · r/rowing and r/sailing, where club coaches and program directors already post about retention, fees and roster tools (community); USRowing's club finder and US Sailing's list of community sailing centers, filtered to clubs that mention scholarship or financial aid (directory); direct email and phone to junior program contacts listed on club websites in harbor towns like Newport, Annapolis, Marblehead and Seattle (channel).

2Sell first, build later

A founding-club season: Slipway digitizes the club's attendance sheet and regatta feed, coaches attest sessions with one tap, and the director gets a weekly flag report of dedicated kids whose payments are lapsing, wired to the club's scholarship fund - live within 7 days of signing, running through the full fall season.

the ask · $450 per club for the first season, locked for one year; $600 per season after.

a real yes · A real yes is a paid $450 invoice or check with a roster handed over. 'The treasurer would love this', unpaid trials and requests to circle back after the board meeting are a no.

3Small experiments

The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.

1. Lapsed-kid loss count
$100 · 10 days
Book 15 calls with program directors from the sources above and ask each to count, from last season, the kids with 10-plus session streaks whose family payments lapsed before they disappeared, and what each departure cost the program. One founder, one script, no demo.
keep going if · 8 of 15 directors name 2 or more such kids and call losing them a real cost, not a shrug.
2. Spreadsheet shadow test
$0 · 14 days
Ask 5 of those clubs to send last season's attendance sheet and payment ledger with names replaced by initials. Cross them by hand into a one-page flag report of dedicated-but-lapsing kids and review it with the director, counting flags they did not already know about.
keep going if · In 3 of 5 clubs the report surfaces at least 1 at-risk kid the director had not spotted - direct evidence the treasurer's spreadsheet misses them.
3. Prepaid founding-club close
$500 · 14 days
Offer the 12 warmest clubs a founding deal: first season prepaid at $450, price locked for a year, roster and flag reports live within 7 days, flagged kids routed to the club's own scholarship fund with the seat paid to the club. Visit the closest 4-5 harbor-town clubs in person to sign; the rest close by phone and invoice.
keep going if · 3 of 12 clubs pay the $450 invoice.

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.

$450

per prospect, refundable

how · First season prepaid in full - the director signs a half-page founding-club agreement and pays $450 by club check or card invoice, the way clubs already pay every vendor. Chosen because a small prepaid season is the exact test of whether this buyer values the flags more than the treasurer's free spreadsheet. set up: Stripe Invoicing ↗

what it reserves · A founding-club slot, the $450-per-season price locked for one year, and setup of the club's own scholarship-fund routing first.

refund · Refundable in full until the roster is loaded and the first weekly flag report is delivered; after that it applies to the season.

target · 3 prepaid seasons from 12 offers within 28 days.

before taking money · Every record leaving a club in the shadow test must be anonymized by the club first, and no named minor's data may ever reach donors or the founders before a signed agreement with the club.

Go: build it if

3 of 12 clubs prepay $450, 8 of 15 directors count 2 or more lost dedicated kids, and the shadow test surfaces unknown at-risk kids in 3 of 5 clubs - build the fall product.

Kill: stop if

0 prepaid seasons after 12 offers, or 8 or more of 15 directors say lapsed dedicated kids are rare, or the shadow test finds nothing directors did not already know - the treasurer's spreadsheet wins, exactly as the card feared.

outreach message

Your best junior this season may be a kid whose family quietly stopped paying in August. Slipway crosses your attendance sheet with your payment ledger and flags the dedicated kids before they disappear, then routes them to your scholarship fund, with the seat paid to the club, never the family. Founding clubs prepay the first season at $450, locked for a year, live within 7 days. Can I get 20 minutes this week to count how many kids you lost that way last season?

The concept in full

What: A roster tool for sailing, rowing and other water sports clubs that logs each kid's attendance streak and regatta results, then flags the dedicated ones whose family payments lapse before they quietly quit. The coach attests a session with one tap, the flagged kid gets routed to the club's parent-funded scholarship fund, and the seat is paid to the club, never the family. The kid sees a private streak and results timeline; donors to the fund see anonymized cohort progress, no named minors.
Grounded in (2025-2026 signals): Aspen Institute Project Play's State of Play 2025 puts average family spend on one child's sport at $1,016 in 2024, up 46% since 2019, with the income participation gap at 20.2 points in 2024. The Universal charitable deduction from 2026 gives standard-deduction filers, about 86% of taxpayers, up to $1,000 ($2,000 joint) for cash gifts, which covers parents paying into a club scholarship fund.
What it rides: Youth sports: $1,016 per child a year, and a gap that widened to 20 points. Slipway sits at the exact moment cost pushes a proven kid out, and turns the club's own attendance data into the retention trigger.
Why now: Family spend hit $1,016 per child in 2024, up 46% since 2019, and from tax year 2026 a parent's $500 gift to the club fund is deductible for the 86% of taxpayers who take the standard deduction, so club funds are filling right as dropout pressure peaks.
Wedge: first customer and entry point: One sailing school that already runs an informal scholarship fund: digitize its attendance sheet and regatta feed in a season, prove one saved kid, then sell the same loop to rowing and swim clubs in the same harbor towns.
Closest real companies, as the generator saw them: Cerebro Sports (PnP 2025) finds basketball players with data, but for scouting, not for funding retention; trophi.ai (speedrun SR004) sells AI coaching with no money loop. Neither connects attendance records to a club scholarship fund.
Main risk: A club treasurer with a spreadsheet and twenty families may never see a reason to pay for software.
