For founders whose AI agents can move money

How to let your AI agent move real money on its own, without it ever moving the wrong money, even if you already set a spend limit

Bring me one workflow where an agent can spend, pay or sign. Within 48 hours you get a written review: where it can overspend, pay twice or be talked into paying someone else, the tests that would catch it, and an honest build or don't-build-yet call.

Free. No keys, no code access and no production access needed.

In their words

Sound familiar?

Builders shipping agents and payments keep running into the same few problems.

  • Spend caps

    “…caps have to live somewhere the agent cannot edit and cannot talk its way past.”

  • Retries that pay twice

    “First implementation doubled a payment because the retry fired before the first transaction confirmed.”

  • Hijacked payments

    “Today the model is the only thing standing between a prompt-injected agent and a signed transaction.”

  • Who authorised it

    “When an agent moves money, someone needs to know who authorized it and who is accountable.”

  • Silent failures

    “We ran this in production for a month without noticing, and it cost us the only buyer we had.”

  • No audit trail

    “…Audit trail: Nobody provides one.”

Why the usual fixes don't hold

  • A budget in the prompt

    A number the model can be argued out of is a suggestion, not a cap. And ten agents can each pass the same limit check before any one of them records its spend.

  • Retry on failure

    Without an idempotency key, a retry after a timeout is a second, valid payment. The agent can't tell "never sent" from "sent, reply lost".

  • Read the logs afterwards

    Logs tell you what happened after it happened. They rarely show which rule allowed a payment, or who approved it, in one record.

  • Wait for a full audit

    Essential for contracts that hold value, and a bigger, slower job. It isn't built to check how your agent's workflow decides to pay.

The free 48-hour integration review

One real workflow, looked at end to end, with the answer written down. You keep the report whether or not we ever work together.

What I look at

  • Where the spending limit really lives, and whether the agent can change it
  • What happens on a timeout, a retry or a duplicate request
  • Which inputs could redirect a payment: web pages, API responses, tool output
  • Who or what approved each payment, and whether you could show it in one record
  • The vendors and SDKs in the path, and what breaks if one of them changes

What you get

  • A written report within 48 hours of a complete intake
  • Fit and dependencies for the workflow
  • Permission risks, ranked by what they could cost
  • Acceptance tests to run before go-live
  • A build or don't-build-yet call, said plainly

What I need from you

  • A 25-minute intake call about the one workflow
  • Public docs and a sanitised diagram or sample
  • Nothing secret: no keys, no code access, no production access

What it isn't. It is an engineering review, not a security audit, a smart-contract audit, or legal, compliance or investment advice. No exploit testing.

  1. 01

    Book the intake

    Pick 25 minutes and tell me the one workflow you're deciding about.

  2. 02

    I review it

    Within 48 hours of a complete intake. If something is missing, I say so before the clock starts.

  3. 03

    You get the report

    Yours to keep. If you later want help building, we scope that separately.

Is this for you?

A good fit

  • Founders and CTOs of identified crypto or fintech teams with a live product or a launch date
  • Agents that pay, trade, sign or hold keys, or are about to
  • One workflow you're deciding whether to ship

Not a fit

  • Anonymous teams, memecoins, or teams with a past rug
  • Anyone who wants me to hold keys or run live trades
  • Value-holding contracts that need an audit: I'll tell you to get an independent one

Who you'll be talking to

I'm Shilpa Goel, founder of Consistra. I build and run AI agent systems, and I hold them to one rule: the model never gets the final say. It suggests; plain, boring checks decide.

That rule matters most when an agent can spend. The cap lives where the agent can't edit it, every payment leaves a record of the rule that allowed it, and a retry can never pay twice.

Internal case studies

Two systems I run myself, as internal case studies, not client work: a plan engine where the model proposes and a set of fixed checks passes or holds every result, so nothing goes out when a check fails; and a multi-agent research engine that reads public sources and checks every quote word for word against the page before it is used.

Questions

Is the review really free?

Yes. No invoice, no card and no obligation. If you later want help building, that is a separate conversation with a written scope.

Do you need our code, keys or production access?

No. A short intake, your public docs and a sanitised diagram are enough. Please don't send secrets.

Is this a security audit?

No. It checks how one workflow handles limits, retries, approvals and inputs. Value-holding contracts need an independent audit, and I'll say so if yours does.

What if the answer is "don't build yet"?

Then the report says that, and why. A clear no is a useful result.

When do the 48 hours start?

When the intake is complete and I've confirmed I can take it. If anything is missing, I tell you before the clock starts.

Bring one workflow. Get a straight answer in 48 hours.

Free, written, and yours to keep.
