$800 · 4 weeks · 20 prospects
For $800 and 4 weeks, this proves that merchants on agent checkout rails are already losing agent-order chargebacks and will put down $500 against a 25% success fee to have them fought.
Riskiest assumption · DTC merchants on agent checkout rails are already receiving 'I did not authorize my agent' chargebacks at 3 or more per month, are losing them, and will pay a 25% success fee to an outside service rather than wait for the card networks to auto-resolve these disputes from the consent record itself.
1Focus group: who and where
The founder or head of operations at a US DTC brand doing $2-20M a year on Stripe or Shopify Payments, live on or adjacent to Stripe's Agentic Commerce Suite, who saw their first 'I never authorized my agent to buy that' disputes this quarter and is answering them with the same generic evidence template they use for stolen-card claims
where to find 20 · The eCommerceFuel forum (paid community of seven-figure store owners who post their dispute problems by name), a BuiltWith export of US stores running Stripe checkout filtered to fashion, accessories and home goods (the verticals of Stripe's ACP launch merchants), and direct threads plus DMs in r/shopify and r/stripe where merchants already post agent-order dispute screenshots
2Sell first, build later
We fight your next 10 agent-order chargebacks for you: we pull the Visa TAP issuer-signed consent record, the token's scope and expiry, and the agent's verified identity into the representment packet and file it through your Stripe dashboard, starting within two weeks of your deposit.
the ask · 25% of every recovered dispute, with a $500 refundable deposit credited against the first success fees
a real yes · A real yes is the $500 deposit paid and dashboard access granted; a signed success-fee agreement before the first filing confirms it. Compliments, 'send me the template', and requests to try it free on one dispute do not count.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Dispute-log evidence calls
$450 · 10 days
Book 15 calls from eCommerceFuel, the BuiltWith list and subreddit threads. On each call ask the merchant to open their Stripe disputes dashboard and count disputes on agent-referred or ACP orders in the last 90 days, and how many they won. Bring a one-page teardown showing the Visa TAP issuer-signed consent record, token scope and agent identity fields that never make it into their current responses.
keep going if · 8 of 15 merchants show at least 3 agent-initiated disputes in the last 90 days and report losing half or more of them
2. Deposit-backed cohort pitch
$100 · 10 days
At the end of each call, pitch the done-for-you offer: we file your next 10 agent-order disputes, you pay 25% of recovered, a $500 refundable deposit reserves one of 10 first-cohort slots. Send a payment link the same day - these merchants already run their business on Stripe, so a payment link is how they expect to pay - with the one-page terms attached.
keep going if · 5 of 15 pitched merchants pay the $500 deposit within 14 days of the call
3. File three real representments
$250 · 14 days
With the first 2-3 depositors, get dashboard access, assemble representment packets by hand from the TAP consent record, token scope and expiry, and agent identity using Visa's compelling evidence format, and file them through the merchant's own Stripe dashboard. The founder does the assembly; the test reads on filings accepted and success-fee agreements signed, not on win rates, which take 30-75 days to return.
keep going if · 10 disputes filed across 3 merchants within 14 days, each merchant signing the 25% success-fee agreement before filing
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.
$500
per prospect, refundable
how · A $500 refundable deposit paid through a payment link sent right after the call - chosen because these merchants run their whole business on Stripe and pay vendors this way daily - credited in full against the first success fees; the merchant also signs a one-page authorization letting the service file responses on their behalf set up: Stripe Payment Links ↗
what it reserves · One of 10 first-cohort slots, filings starting within two weeks, and the 25% success-fee rate locked for 12 months
refund · Refunded in full any time before the first filing, or automatically if nothing is recovered within 60 days of the first filing.
target · 5 deposits from 15 pitched merchants within 30 days
Go: build it if
5 merchants pay $500, at least 10 real agent-order disputes are handed over, and 3 signed success-fee agreements exist within 4 weeks
Kill: stop if
Fewer than 3 of 15 merchants can show a single agent-order dispute in their last 90 days, or fewer than 2 deposits after 15 pitches - either means the dispute volume or the willingness to pay is not there yet

outreach message
You are on Stripe and starting to see orders placed by shopping agents instead of humans. When a cardholder claims their agent was not authorized, that chargeback is winnable: Visa's agent checkout attaches an issuer-signed consent record that almost no merchant puts in the representment. I pull that record, the token scope and the agent's verified identity into the response and file it for you. You pay 25% of what is recovered, nothing otherwise. Can I get 20 minutes this week to look at your last 90 days of disputes?

The concept in full
- What
- An agent service that fights chargebacks on agent-initiated orders. When a cardholder claims they never authorized a purchase their agent made, it assembles the Visa TAP issuer-signed consent record, the token's scope and expiry, and the agent's verified identity into a representment packet and files the response. Merchants pay per recovered dispute.
- Grounded in (2025-2026 signals)
- Visa's Trusted Agent Protocol (September 2025) issues 'a verified agent identity plus an issuer-signed consent record', which is purpose-built dispute evidence nobody is operationalizing: the keyword data shows 1 company mentioning 'chargeback' in the last two years against 7 alive all-time. Mastercard Agent Pay (April 2025) binds each Agentic Token to one consent policy.
- What it rides
- Visa TAP and Mastercard Agent Pay, by turning their consent records and token bindings into dispute evidence; ACP's Shared Payment Token scope serves the same role for Stripe-side orders
- Why now
- The first full year of consumer agent purchases at scale is 2026, with Stripe's Agentic Commerce Suite live at Coach, URBN, Revolve and Etsy, and 'I didn't authorize my agent to buy that' disputes have no established evidence playbook while only 1 tracked 2025-2026 company touches chargebacks at all.
- Wedge: first customer and entry point
- Merchants on the Agentic Commerce Suite seeing their first agent-order disputes; start as a done-for-you service on Stripe ACP orders where token scope data is accessible, and codify the winning evidence templates per card network.
- Closest real companies, as the generator saw them
- Socratix AI (yc S25) builds AI coworkers for fraud and compliance teams, upstream of disputes; MouseCat (yc W26) fights financial crime, not merchant representment. Neither handles agent-purchase chargebacks.
- Main risk
- Card networks write agent-order dispute rules that auto-resolve from the consent record itself, leaving no evidence work to sell.
