$900 · 4 weeks · 27 prospects
For $900 in 4 weeks, this proves whether mid-size issuer processors will pay $5,000 now for agent-payment authorization controls or sit on their hands waiting for Visa and Mastercard.
Riskiest assumption · Mid-size issuer processors and sponsor banks will commit budget and a dated start this quarter for agent-payment authorization controls, rather than waiting for Visa and Mastercard - which are already shipping issuer-signed consent records and Intelligent Commerce tooling - to solve it at the network level for free.
1Focus group: who and where
Head of fraud strategy, risk product or card program management at a US mid-size issuer processor or banking-as-a-service sponsor bank - the tier below Fiserv and FIS that runs fintech card programs - who is already fielding step-up and decline decisions on scripted transactions and getting the first agent-initiated authorization questions from fintech clients.
where to find 27 · American Fintech Council member companies and working groups; the Nilson Report's published rankings of US issuer processors and program managers used as the call list; warm introductions this week through fintech founders whose card programs run on Marqeta, Lithic or Galileo, who can pull in their processor risk and account contacts; and Money20/20 USA in Las Vegas in late October for in-person closes if any deal is still open then.
2Sell first, build later
A 90-day design-partner pilot sold before production code exists: Tollbridge co-writes the processor's agent-spend policy framework with its risk team, scores 90 days of one fintech card program's redacted or synthetic authorization data against it, and delivers the policy spec plus a decisioning report the processor can put in front of its bank partners, with kickoff within 30 days of signature.
the ask · $5,000 per pilot, invoiced up front, credited in full against a $3,000-per-month per-program subscription on conversion
a real yes · A real yes is a signed pilot scope with a dated kickoff plus a paid invoice or issued purchase order. 'Send the deck for 2027 planning,' unpaid proofs of concept and innovation-team enthusiasm are noes.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Budget-and-date close
$900 · 21 days
Run 12 calls with fraud and risk product heads at processors and sponsor banks, armed with a designed two-page pilot spec and a mocked policy-engine walkthrough. The pitch: a 90-day design-partner pilot - co-write the agent-spend policy framework, then score 90 days of one card program's redacted or synthetic authorization data against it, $5,000 invoiced up front, kickoff dated in the scope. Includes travel for two in-person closes.
keep going if · 2 of 12 sign a scoped pilot with a kickoff date and pay the $5,000 invoice or issue a PO
2. Card-program pull test
$0 · 10 days
Run 15 short calls with fintech founders and card-program leads (the processors' customers): are agent or scripted purchases showing up, getting declined, generating support tickets. Ask each with live pain to co-sign a one-paragraph pilot request addressed to their processor - demand pulled through the channel the card says distribution runs on.
keep going if · 5 of 15 report live agent-transaction pain and co-sign the pilot request
3. Wait-for-Visa gauge
$0 · 7 days
Send every call participant a written five-question follow-up: is agent-payment risk a budgeted 2026-27 line, on what timeline, and would they deploy a third-party control layer before Visa's Intelligent Commerce tooling reaches their programs. This puts a number on the single objection every judge raised.
keep going if · At least half of interested prospects state in writing they will not wait 12+ months for a network solution
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.
$5,000
per prospect, refundable
how · A $5,000 design-partner fee invoiced up front against a two-page scope signed by the processor's head of risk or product, with a purchase order accepted where AP requires it - chosen because a mid-size processor can pay a consulting-size invoice without full vendor onboarding, provided the pilot never touches production systems. set up: Stripe Invoicing ↗
what it reserves · One of 3 design-partner slots, the policy framework co-authored with their team, the first production integration slot, and the fee credited to year one of the subscription
refund · Refunded in full if Tollbridge misses the 30-day kickoff or fails to deliver the scored report within the 90-day window.
target · 2 paid $5,000 pilots from 12 processor conversations within 30 days
before taking money · Because the buyers are banks and their processors, the pilot must stay on synthetic or redacted data - no production authorization streams and no cardholder PII - until the buyer's vendor security review and a GLBA counsel check are complete.
Go: build it if
2 signed and paid $5,000 pilots with kickoff dates inside 30 days, 5+ card programs attesting to live agent-transaction pain, and half of interested buyers stating in writing they will not wait for the networks - budget exists now.
Kill: stop if
0 paid pilots from 12+ conversations and a majority of prospects saying in writing they will wait for Visa and Mastercard network features - stop, or reposition to sell through the networks rather than around them.
5 Scripts to run itoutreach message, landing copy, deposit terms · click to open
outreach message
Your fintech programs are starting to see card-not-present traffic that isn't a person - agent and scripted purchases your current rules can only treat as account takeover. I'm building Tollbridge, the policy and agent-identity layer issuers run on the authorization stream. Before we write production code, I'm signing 3 processors for a $5,000, 90-day design pilot: we co-write your agent-spend policy and score 90 days of your historical auth data against it, redacted or synthetic, no production access. Can I get 20 minutes this week?

Let AI agents spend on your cards, safely. $5,000 design-partner pilot: a co-written agent-spend policy framework plus 90 days of historical authorization data scored, delivered inside 90 days. Book a 20-minute scoping call - 3 slots
deposit terms
The $5,000 pilot fee, invoiced at signature, reserves one of 3 design-partner slots with kickoff inside 30 days. It covers the co-written agent-spend policy framework and retrospective scoring of one card program's redacted or synthetic authorization data; no production systems or cardholder PII are touched. Fully refunded if we miss kickoff or fail to deliver the scored report within 90 days, otherwise credited in full to your first-year subscription.

The idea in full
- What
- Enterprise SaaS sold to US card issuers and issuer processors that adds an agent-payments control plane: banks define spend policies, verify which AI agent is transacting on whose mandate, and score every agent-initiated authorization in real time. Agent and wallet developers integrate a free SDK to get their agents accepted, so the product becomes the platform both sides build against. Revenue starts within a year as per-issuer subscription plus a per-authorization fee.
- Why now
- Agentcard (yc S26) is already issuing debit cards for AI agents, and 217 new fintech companies were tracked in this cluster in the last two years, but issuers still have no standard way to distinguish a legitimate agent purchase from account takeover. The control layer has to sit with the bank, and nobody in the brief sells it there.
- Wedge: first customer and entry point
- One mid-size issuer processor pilot: a policy engine and agent-identity check bolted onto their existing auth stream for a single fintech card program, live in 90 days.
- Path to 100x
- US card volume runs in the trillions annually and even a few percent shifting to agent-initiated commerce creates a $10B+ authorization-infrastructure layer; whoever aggregates cross-issuer agent behavior data scores fraud better than any single bank can, so issuers converge on one standard. Distribution through processors means one channel deal covers hundreds of banks, giving the standard-setter winner-takes-most economics on a per-transaction toll.
- Ceiling
- If agent commerce stays below 1 percent of card volume for a decade, this is a $100M compliance vendor, not a platform.
- Closest real companies, as the generator saw them
- Agentcard issues cards to agents directly; Tollbridge is the neutral control and verification layer issuers run across every card program, so it wins even if many Agentcards exist. Notabene, Inc. does compliance messaging between VASPs, not card authorization.
- Main risk
- Visa and Mastercard ship agent-verification as a network-level feature and issuers wait for it instead of buying.
Five judges
Each judge scores every idea in the catalog with a named rubric; the venture judge decides whether a card is shown at all (4-5 is venture-grade).
Venture investor
4/5
Per-authorization toll on trillions in card volume with cross-issuer behavior data compounding, distributed through processors that cover hundreds of banks per deal.
Bootstrapper
3/5
Revenue within a year through one processor is real, but issuers only budget once agent commerce exists beyond Agentcard pilots.
Operator
2/5
Issuers cannot feel a pain that is under 1 percent of card volume, and they will wait for Visa and Mastercard to ship it.
Technologist
2/5
The card names its own killer: Visa and Mastercard can ship agent verification as a network feature in one release.
Risk
2/5
Depends on issuer processors for distribution and on Visa and Mastercard not shipping agent verification at network level, which the card admits.
trends
3/5
Timing is exactly 2026, but Visa's issuer-signed consent records and Intelligent Commerce Connect show the networks already shipping the verification layer Tollbridge sells.
