Mintgate
Policy engine deciding when an agent gets a scoped payment token
Mintgate sits between an agent builder's product and the payment rail: every token request is checked against per-agent budgets, merchant allowlists, velocity limits and time windows before a scoped token is minted.

Test it before you build it
$150 · 3 weeks · 25 prospects
For about $150 and 3 weeks, learn whether founders wiring agents into Stripe's ACP will prepay $250 for a policy layer they could attempt to write themselves.
Riskiest assumption · Seed-stage founders integrating ACP will pay a separate vendor for token policy rather than using whatever controls Stripe ships in the Agentic Commerce Suite or writing the if-statements themselves.
1Focus group: who and where
Founder or founding engineer at a 2-10 person seed-stage AI agent startup whose agent can already place an order and who is integrating Stripe's Agentic Commerce Protocol or another agent checkout this quarter, currently hand-rolling budget caps and merchant allowlists.
where to find 25 · The r/AI_Agents subreddit where these builders post integration questions; the YC Startup Directory filtered to W26 and S26 companies describing agents that buy, book or order (a public list you can work through in an afternoon); and your city's AI Tinkerers meetup, which runs monthly in SF, NYC, Seattle and Austin and is where agent builders demo.
2Sell first, build later
A founding-member slot in the first cohort: the Mintgate policy SDK answering every token request against per-agent budgets, merchant allowlists, velocity limits and time windows, live in their staging environment within 21 days, with a founder in their Slack during integration.
the ask · $250 per month per product, first 1,000 policy decisions free, founding price locked for 12 months
a real yes · A real yes is a completed $250 card checkout; a doc signup, a 'we'd definitely use this', a GitHub star, or an unpaid staging trial is not a yes.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Spend-control pain interviews
$0 · 10 days
Get 20 fifteen-minute calls with founders sourced from the YC directory list, r/AI_Agents DMs and one AI Tinkerers meetup. Ask what happens today if their agent tries to spend $5,000 at the wrong merchant, what code they wrote to stop it, and what that code cost them in launch time. Log whether each one built custom controls, delayed launch over it, or shipped with nothing.
keep going if · 8 of 20 have written custom budget or allowlist code, or delayed an agent launch because they had not
2. Docs-first priced page
$120 · 7 days
Publish real-looking API reference docs for the one call ('should this agent get this token'), covering budgets, allowlists, velocity limits and denial reasons, with pricing on the page: first 1,000 decisions free, then $250 per month. Post it in r/AI_Agents, share it in the interview follow-ups, and demo the docs at AI Tinkerers. Count signups and booked integration calls.
keep going if · 25 signups on the docs page and 8 of them book an integration call
3. Founding cohort prepay
$30 · 7 days
Offer the interviewed founders 10 founding-member slots: first month prepaid at $250 via card checkout, price locked for 12 months, integration help from a founder on a shared Slack channel. Card checkout is the right instrument here because this buyer is a self-serve developer who pays for tools by card the same day. Count who actually pays.
keep going if · 5 of 10 offered slots are prepaid within a week of the offer
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.
$250
per prospect, refundable
how · First month prepaid at $250 through a card checkout on the docs page: the founder pays at signup, no contract to sign. For a self-serve developer buying a per-month tool, same-day card payment is the honest test; an invoice or LOI would let them say yes without spending anything. set up: Stripe Invoicing ↗
what it reserves · One of 10 founding slots, the $250 price locked for 12 months, and founder-led integration support in a shared Slack channel
refund · Refunded in full if the SDK is not running in their staging environment within 21 days of payment.
target · 5 prepaid founding members from 25 conversations within 21 days
before taking money · Mint only sandbox tokens during the test; do not hold or move real payment tokens before counsel reviews money-transmission and PCI exposure.
Go: build it if
5 founders prepay $250 and at least 8 of 20 interviews confirm they built or delayed over custom spend controls.
Kill: stop if
Fewer than 2 prepayments from 25 conversations, or a majority of interviewees saying Stripe's built-in ACP controls already cover budgets and allowlists for them.

outreach message
Saw you're wiring your agent into ACP. Right now, what stops it from spending $5,000 at the wrong merchant at 3am? I'm building Mintgate: one API call that checks every token request against per-agent budgets, allowlists and velocity limits before the token is minted, with every denial logged with a reason. First 1,000 decisions free, $250 a month after, and I'm taking 10 founding teams. Got 15 minutes this week to show me how you handle spend controls today?

Should this agent get this token? One API call. $250 a month, first 1,000 policy decisions free: per-agent budgets, merchant allowlists, velocity limits and logged denials, founding price locked for 12 months Claim one of 10 founding slots
deposit terms
You're paying $250 today for your first month as a founding member: one of 10 slots, price locked for 12 months, and a founder in your Slack during integration. If the SDK isn't running in your staging environment within 21 days, we refund the full amount. Your first 1,000 policy decisions are free before metering starts.

The concept in full
- What
- Mintgate sits between an agent builder's product and the payment rail: every token request is checked against per-agent budgets, merchant allowlists, velocity limits and time windows before a scoped token is minted. Builders ship agents that can buy without writing their own controls, and every denial is logged with a reason.
- Grounded in (2025-2026 signals)
- The Agentic Commerce Protocol published by Stripe and OpenAI in 2025, packaged in 2026 as the Agentic Commerce Suite used by Coach, URBN, Revolve, Etsy, Squarespace, Wix, WooCommerce and BigCommerce; Orthogonal (yc W26) doing agentic payments for APIs; Shopify reporting orders from AI search up nearly 13x in Q1 2026.
- What it rides
- Stripe: ACP, shared payment tokens, Tempo: ACP completes a purchase with a Shared Payment Token scoped to one merchant, one amount and a short expiry. Mintgate is the decision layer that determines whether that token should exist at all, per agent and per policy.
- Why now
- With the Agentic Commerce Suite live across eight named merchants and platforms in 2026 and Shopify's AI-driven orders up nearly 13x in Q1 2026, agent builders are wiring token requests today, before any of them has a policy layer between the agent and the mint.
- Wedge: first customer and entry point
- Seed-stage agent startups integrating ACP: a drop-in SDK that answers 'should this agent get this token' in one call, sold self-serve with the first thousand policy decisions free.
- Closest real companies, as the generator saw them
- Orthogonal (yc W26) provides the payment rail for agentic API payments; Mintgate is rail-agnostic policy on top of ACP, Agent Pay or TAP. IRBC (yc X25) is a full financial institution for businesses and agents, not an embeddable control layer.
- Main risk
- Stripe adds configurable per-agent policy rules directly into the Agentic Commerce Suite and the standalone layer becomes a feature.
