Dispute and refund rails for payments agents make on their own
An API that PSPs and commerce platforms plug in to handle what happens after an agent purchase goes wrong: it assembles the scoped token, consent record and delivery evidence into a machine-readable case file, routes refunds without a human filing anything, and gives issuers a consistent liability trail for agent-initiated transactions.

Test it before you build it
$1,200 · 6 weeks · 20 prospects
Prove in 6 weeks and $1,200 that a mid-size PSP will pay $4,000 up front to have agent-initiated disputes evidenced and filed by an API instead of by its own analysts.
Riskiest assumption · Disputes leaders at mid-size PSPs are already seeing agent-initiated transactions fail into chargebacks their tooling cannot evidence, at enough volume and write-off cost that they will pay per case for an independent rail before Visa and Mastercard mandate their own evidence format.
1Focus group: who and where
Head of disputes, risk operations or chargebacks at a mid-size US PSP or commerce platform processing $100M-$5B a year, whose merchants already take ACP or other agent-initiated orders and whose team is hand-assembling evidence for those disputes this quarter.
where to find 20 · The Merchant Risk Council (MRC) member community, where dispute leads at exactly these companies compare notes; the Nilson Report rankings of US acquirers and payment facilitators to build the named target list; Risk Salon, the invite practitioner community for fraud and risk leads; warm intros through payments-focused investors and former colleagues.
2Sell first, build later
A 60-day design-partner pilot on one payment flow: machine-readable case files assembled for up to 50 agent-initiated disputes, delivered into the PSP's existing representment queue, starting within 30 days of signing.
the ask · $4,000 per pilot, invoiced up front; converts to $12 per case, locked for year one
a real yes · A real yes is the paid $4,000 invoice or a signed LOI with a dated start and a named dispute flow; enthusiastic feedback on the sample case file, an unpaid trial, or an intro to procurement with no date does 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 queue interviews
$300 · 14 days
Build a list of 40 mid-size PSPs and ACP-enabled platforms from the Nilson rankings, reach their disputes leads through MRC connections and warm intros, and run 15 calls asking three numbers: agent-initiated disputes seen in the last 90 days, representment win rate on them, and write-off per case. One founder runs the calls and logs every number.
keep going if · 8 of 15 leads can point to real agent-transaction disputes in their queue from the last 90 days, and none has a dedicated evidence format for them
2. Sample case file review
$200 · 10 days
Hand-build one machine-readable case file from the public ACP spec for a simulated failed agent purchase: scoped token, consent record, delivery evidence, assembled the way an issuer would read it. Walk 10 interviewees through it on a screen share and ask whether it would change the outcome of a case they lost.
keep going if · 5 of 10 reviewers say it would strengthen a representment today and ask to run it against a real case from their queue
3. Paid dispute-desk pilot
$700 · 21 days
Offer the 5 warmest PSPs a 60-day pilot: Recourse Labs assembles the case file for up to 50 agent-transaction disputes on one named payment flow, delivered into their existing representment process, $4,000 invoiced up front. Have a startup attorney review the pilot agreement and a light data-handling addendum once; the PSP executes all refunds on its own rails.
keep going if · 1 of 5 offers is signed and the $4,000 invoice paid, or 2 signed LOIs with dated starts where procurement blocks prepayment
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.
$4,000
per prospect, refundable
how · A 60-day paid design-partner pilot invoiced up front and signed by the head of risk; where the PSP's procurement cannot pay before vendor review, collect a signed LOI naming the dispute flow, the pilot start date and the $4,000 fee instead. set up: Stripe Invoicing ↗
what it reserves · One of two pilot slots, first position in the integration queue, and a per-case price of $12 locked for the first year.
refund · Full refund if the first 10 case files are not delivered within 21 days of the pilot start date.
target · 1 paid pilot, or 2 signed LOIs with dated starts, from 15 conversations within 45 days
before taking money · During the test, only assemble evidence and recommend outcomes; the PSP must execute every refund on its own rails, since moving refund funds yourself can require money transmitter licensing.
Go: build it if
1 PSP pays the $4,000 pilot invoice and 8 of 15 disputes leads confirm live agent-transaction disputes with no evidence format for them.
Kill: stop if
Fewer than 4 of 15 leads can point to any agent-initiated dispute in their last 90 days, or 0 paid pilots and 0 signed LOIs after 5 formal offers.

outreach message
You're seeing agent-placed orders come through ACP, and when one goes wrong your team assembles the token, consent record and delivery evidence by hand for a dispute process the networks never designed for agents. I'm building Recourse Labs: a machine-readable case file for every agent dispute, dropped straight into your representment flow. I'm running two paid 60-day pilots at $4,000, covering up to 50 disputes on one flow. Worth a 20-minute call to walk through a sample case file?

deposit terms
Pay $4,000 today to reserve one of two 60-day pilot slots starting within 30 days. The pilot covers case-file assembly for up to 50 agent-initiated disputes on one payment flow and locks your per-case price at $12 for the first year. Full refund if the first 10 case files are not delivered within 21 days of your start date.

The concept in full
- What
- An API that PSPs and commerce platforms plug in to handle what happens after an agent purchase goes wrong: it assembles the scoped token, consent record and delivery evidence into a machine-readable case file, routes refunds without a human filing anything, and gives issuers a consistent liability trail for agent-initiated transactions.
- Grounded in (2025-2026 signals)
- Stripe's ACP (2025, Meta joined later) with Shared Payment Tokens, packaged in 2026 as the Agentic Commerce Suite used by Coach, URBN, Revolve, Etsy, Squarespace, Wix, WooCommerce and BigCommerce. Visa's Trusted Agent Protocol (September 2025) with issuer-signed consent records. Keyword coverage shows 'chargeback' in only 1 company pitch in the last two years.
- What it rides
- Agent checkout protocols end to end: ACP's Shared Payment Token scoped to one merchant, one amount and a short expiry, plus Visa TAP's issuer-signed consent record, are exactly the evidence a dispute needs, and today nobody assembles them into one.
- Why now
- By 2026 ACP runs live across eight named platforms and Shopify reported AI-driven orders up nearly 13x in Q1 2026, so agent-initiated purchase volume is real, yet the radar shows exactly one 2025-2026 company mentioning chargebacks; the failure path of every one of those transactions is unbuilt.
- Wedge: first customer and entry point
- One mid-size PSP whose merchants take ACP orders: intercept its agent-transaction disputes, prove faster resolution and lower write-offs on that single flow, priced per case.
- Closest real companies, as the generator saw them
- Didit (yc W26) covers identity and fraud at transaction time, not the post-purchase dispute; Socratix AI (yc S25) staffs fraud and compliance teams with AI coworkers rather than providing dispute rails; none tracked handle agent-purchase refunds specifically.
- Main risk
- Card networks fold agent-dispute handling into existing chargeback machinery and mandate their own evidence format before an independent layer gains adoption.
