Attestly

Receipts, acknowledgments and good-standing proof for charities facing first-time deductors

Software for small nonprofits that automatically issues IRC 170(f)(8)-compliant contemporaneous written acknowledgments, produces the January statement donors will need for the new deduction, and maintains a live good-standing pack: state charity registration, IRS status, filing history.

Test it before you build it

$600 · 3 weeks · 30 prospects

For $600 and 3 weeks, prove that executive directors of sub-$2M charities will prepay $149 for compliant receipts, the January donor statement, and a live good-standing pack.

Riskiest assumption · An executive director of a sub-$2M charity will pay a monthly fee for compliant acknowledgments and good-standing proof even though donation-form vendors bundle basic receipting for free, which is the card's stated commoditization risk.

1Focus group: who and where

The executive director (often also the bookkeeper) of a 501(c)(3) under $2 million in revenue, especially one that just lost a government grant or sits on California's delinquency list, staring down a first tax season where every donor can claim the new deduction and will ask for paperwork.

where to find 30 · The California AG Registry of Charitable Trusts delinquency list filtered to sub-$2M organizations; CalNonprofits (California Association of Nonprofits) membership and events; the r/nonprofit subreddit where EDs already ask receipt and acknowledgment questions; a second state association from the National Council of Nonprofits network to check the demand is not California-only.

2Sell first, build later

Deduction-ready in 30 days: automatic IRC 170(f)(8) acknowledgments on every gift taken on the charity's own site, the consolidated January 2027 donor statement, and a live good-standing pack (state registration, IRS status, filing history), with setup finished before the January statement run.

the ask · $49 per month list; founding charities prepay $149 for the first six months and keep $29 per month locked through 2027

a real yes · A real yes is $149 charged to the organization's card; 'this looks great, send it to my board' and requests for a free trial are noes.

3Small experiments

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

  1. 1. Fifteen ED prepay calls

    $300 · 14 days

    Pull 60 sub-$2M charities from the CA AG delinquency list and CalNonprofits, email and call until 15 EDs take a 20-minute call. The founder demos a mocked receipt, the January statement, and the good-standing pack, then makes the $149 founding-member ask and sends the checkout link while still on the call.

    keep going if · 4 of 15 EDs prepay $149 within 48 hours of the call

  2. 2. Delinquency-list cold email

    $100 · 7 days

    Email 100 charities currently marked delinquent or suspended in the CA AG registry with a subject line about the five-business-day platform cutoff and one line on what lapsed standing now costs them in platform revenue. Every reply gets offered a call from experiment one's calendar.

    keep going if · 8 of 100 reply and 5 book a call

  3. 3. Priced page with checkout

    $200 · 10 days

    Put up a one-page site: $49 per month list price, the founding offer, and a card checkout, because an ED buys software with the organization's card and there is no procurement to wait for. Point all email and call traffic at it and read the funnel.

    keep going if · 5 of the first 60 visitors start checkout and 3 complete it

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.

$149

per prospect, refundable

how · Founding-member prepayment through card checkout on the landing page, sent live during the call; this buyer pays with the org card same-day or not at all, so an invoice cycle would only hide the truth. The ED clicks pay, no signatures. set up: Stripe Invoicing ↗

what it reserves · One of 10 founding-charity slots: setup completed before the January 2027 donor statement run and $29 per month locked through 2027

refund · Full refund any time before the charity's January 2027 donor statements are generated, no questions asked.

target · 8 prepaid founding members from 15 calls and 100 emails within 21 days

before taking money · Do not hold or route any donation funds during the test, and present the good-standing pack as records monitoring, not legal or tax advice.

Go: build it if

8 or more founding-member prepayments ($1,192 collected) inside 3 weeks, with at least half coming from the delinquency-list angle or grant-loss charities the wedge names.

Kill: stop if

Fewer than 3 prepayments after 15 completed calls and 100 emails, or a majority of EDs say their donation-form vendor's free receipting already covers them, which is the card's stated risk arriving on schedule.

outreach message

Every donor you receipt from now on may claim the new $1,000 deduction, and California's five-business-day cutoff now turns a lapsed filing into lost platform revenue the same week. I'm building software that issues compliant acknowledgments automatically, generates the January statement your donors will ask for, and keeps your state registration and IRS standing in one live pack. Founding charities prepay $149 for six months and keep $29 a month through 2027. I'm signing 10 before the January statement run. Do you have 20 minutes this week?

The concept in full

What
Software for small nonprofits that automatically issues IRC 170(f)(8)-compliant contemporaneous written acknowledgments, produces the January statement donors will need for the new deduction, and maintains a live good-standing pack: state charity registration, IRS status, filing history. It takes cost out by naming what is skipped: a charity running Attestly can take gifts on its own site by ACH and card without a giving platform's percentage and tip, because the platform's back-office jobs this replaces are receipt issuance and eligibility attestation; the charity pays a flat monthly fee. The good-standing pack is also its fraud defense, evidence beyond the 501(c)(3) letter that TIGTA showed is obtainable by fictitious organizations.
Grounded in (2025-2026 signals)
OBBBA deduction effective tax year 2026 for 86% of filers. AB 488 first annual platform reports due July 15, 2025, and a cease-and-desist issued to a platform in November 2025, with other states drafting platform rules (December 22, 2025). Urban Institute: one in three nonprofits lost government funding in early 2025 and is turning to individual donors. Keyword coverage shows only 1 company in the last two years mentioning 'nonprofit', so the cohorts are empty here.
What it rides
Universal charitable deduction from 2026, plus California enforces its fundraising-platform law: AB 488 platforms must drop charities out of good standing within five business days, so charities need their standing documented continuously.
Why now
Every gift a small charity receives from January 2026 onward is potentially a deduction claim by a donor who has never asked for a receipt before, and AB 488's five-business-day cutoff, now actually enforced as of November 2025, makes lapsed state filings an immediate revenue event.
Wedge: first customer and entry point
Charities under $2 million in revenue that just lost government grants; sell through state nonprofit associations as the cheap way to become deduction-ready and platform-proof.
Closest real companies, as the generator saw them
Metal (speedrun SR005) sells fundraising intelligence, not substantiation and compliance paperwork; none tracked otherwise.
Main risk
Donation-form vendors bundle compliant receipting for free and Attestly is reduced to the good-standing monitor alone.
