What Modern Treasury actually is
Modern Treasury sells the software that surrounds a bank account. In the model it was built on, the customer keeps its own accounts at its own banks and Modern Treasury supplies the connectivity into them, the interface for initiating payments, the approval workflow governing who can release money, a double-entry ledger, and automated reconciliation matching what the bank reports against what the business expected. The bank holds the money. Modern Treasury holds the record of it.
Two things it is not. It is not a bank: no charter, and in the original model no funds. It is not a card acquirer: it does not underwrite merchants for card acceptance, sells no checkout, terminal or point-of-sale product, and its only card capability is push-to-card payouts. A business whose real question is "how do I take a credit card" is looking at the wrong company.
Since 2025 it has also sold a fuller product: a payment service provider offering with managed payment accounts, KYB and KYC checks, AML transaction monitoring and program management, under which a customer goes live without arranging its own bank partner and adds direct bank relationships later inside the same integration. That is a materially different proposition from the software-over-your-own-banks product of 2019, and a buyer should be clear which is on the table.
How the money moves, and who carries what
In the classic model the division of responsibility is clean, and worth stating plainly because it determines who answers when something goes wrong.
- The customer's bank holds the funds, executes the transfer and carries settlement.
- The customer owns the banking relationship, the account agreements and the compliance obligations attached to them.
- Modern Treasury supplies initiation, approvals, the ledger, status tracking, return handling and reconciliation.
So when an ACH debit comes back unpaid, when an approver releases a payment they should not have, or when a bank declines to serve a customer type, both the liability and the decision sit outside Modern Treasury. It also explains a gap that looks like an omission and is not one: Modern Treasury publishes no restricted-business list of the kind every card acquirer maintains, because acceptable-use decisions belong to the customer's own bank.
As of July 2026 the supported rails are ACH and same-day ACH, domestic wires, RTP, FedNow, checks, push-to-card, stablecoins and global USD accounts, with SWIFT listed as coming soon. On 6 July 2026 the company completed FedNow Service certification for credit transfers in both directions and for Request for Payment, connecting through the Federal Reserve's FedLine Advantage, and disclosed that 73% of volume through its PSP product in May 2026 traveled over real-time rails.
The PSP model is less well documented. Modern Treasury supplies the accounts, runs onboarding checks and monitoring, and manages the program — but names no bank partners publicly, and does not state whether it holds money transmitter licenses or where. Both are fair questions to put in writing before signing.
How Modern Treasury prices
Modern Treasury publishes the shape of its pricing and none of the numbers. Its pricing page sets out three components: platform access; payment usage priced by rail, so ACH, wires, RTP and FedNow, push-to-card and stablecoins each carry their own unit cost; and accounts and compliance, covering KYB and KYC checks and ongoing transaction monitoring. There is no rate card, no tier and no published starting point.
The structure it does publish matters more than most rate cards would. Terms are annual and usage-based, and a minimum commitment applies — with platform and usage fees both counting toward one commitment rather than two separate floors. The company states that pricing depends on volume, rails used and account structure, and that per-unit costs fall as volume rises. Early-termination terms are not published.
That makes the cost a floor with a meter on top, not a meter alone. A lender, payroll provider or insurer with steady volume will barely notice. A business with a seasonal shape — a title company in a slow market, a marketplace concentrated in Q4 — should model the quiet quarters first, because the commitment does not shrink to match.
Where it is genuinely strong
ACH origination with reconciliation attached. Originating debits and credits, including same-day, is not rare; banks do it and so does every ACH API vendor. What Modern Treasury built around it is the part teams underestimate — return handling, status tracking across the life of a transaction, and automated matching of bank activity against expected payments. Reconciliation is where in-house builds decay: unglamorous, permanently unfinished, and the first thing to break when a bank changes a file format.
Real-time rails. Modern Treasury supports RTP and completed FedNow certification in July 2026 for credit transfers and Request for Payment. The 73% real-time share reported for May 2026 PSP volume is self-published, but specific and recent, and indicates a product being bought for instant payments rather than merely capable of them.
Multi-bank orchestration, on a strong developer surface. One API and one operations layer spanning several banks and several rails is the company's central proposition. A company with accounts at three banks otherwise maintains three connections, three file formats, three sets of cut-off times and three reconciliation processes, and gains a fourth of each when it adds a bank. Modern Treasury is sold as a documented REST API with SDKs and a dashboard, and the double-entry ledger offers to be the system of record for balances — otherwise something engineering teams build badly alongside their bank integrations.
Fiat and stablecoins through one interface. Modern Treasury markets a single API covering both and lists stablecoin orchestration as a named use case; Anchorage Digital is a named customer.
Where it falls short
Judging a bank-rails company for having no card terminals is a category error. These are the limits that bite the customers it actually targets.
- No acceptance and no billing layer. Online checkout, point-of-sale, contactless and wallet acceptance are all absent; card involvement stops at push-to-card payouts. Recurring bank debits can be originated through the API, but there is no subscription billing, dunning, invoicing or payment link product.
- Not a card payment facilitator. Embedded ACH and programmatic sub-accounts are supported, but Modern Treasury is not a registered payment facilitator and does not onboard card sub-merchants. Software companies planning to embed payments should confirm this early, because "embedded" covers both things in vendor marketing and only one of them here.
- The rail list is American. ACH, domestic wires, RTP, FedNow and checks are US schemes, SWIFT was still listed as coming soon in July 2026, and there is no marketed coverage of SEPA, Faster Payments, UPI, PIX or comparable domestic rails. Cross-border runs through global USD accounts instead. Acceptable use is also undefined at the vendor level, since the bank decides — so a customer in an unusual sector has no Modern Treasury policy to read.
- Very little published evidence of current scale. No revenue, no headcount, no current volume. The last self-published monthly figure — over $2bn — comes from an October 2021 funding announcement; the only more recent number is over $400bn cumulative, from the December 2025 Beam announcement.
Ownership, funding and direction of travel
Modern Treasury was founded in 2018 by Dimitri Dadiomov, Matt Marcus and Sam Aarons, is headquartered in San Francisco with a New York office, and is private and investor-backed; named investors include Altimeter Capital, Benchmark and Quiet Capital. One oddity: the company's own October 2021 announcement gives the chief executive title to Matt Marcus and president to Dimitri Dadiomov, conflicting with press coverage naming Dadiomov as chief executive. The discrepancy is unresolved in public.
The October 2021 Series C raised $85m at a valuation above $2bn, led by Altimeter. The company said then that it was processing over $2bn a month, up from $10m two years earlier. No subsequent round, total funding figure or current valuation could be confirmed — for a 2021-vintage growth company, itself a data point rather than a non-event.
In December 2025 it acquired Beam, a full-stack payments platform covering ACH, wire, RTP, FedNow and stablecoins; terms were not disclosed. In the same announcement the company said it had processed over $400bn to date and set out plans for fully managed payment accounts and program management during 2026 — the plan that became the PSP product. The FedNow certification of 6 July 2026 belongs to the same arc: own more of the stack, and push volume onto rails that settle in seconds.
On regulatory posture, the company publishes product rather than licensing. KYB, KYC and transaction monitoring are sold as a priced platform component, and FedNow connectivity runs through FedLine Advantage. Money transmission licensing is not addressed in its public material at all.
How to evaluate Modern Treasury
Diligence here differs from evaluating an acquirer: the risk sits in the bank relationship and the contract, not in underwriting and chargebacks.
- Establish which product you are buying — software over accounts you own, or the PSP stack with managed accounts. The answer changes who holds your funds, who your regulated counterparty is and what happens if the relationship ends.
- If it is the PSP product, ask which bank. Get the partner bank named in writing, with who is account holder of record, who holds customer funds, which money transmitter licenses apply, and what happens to your balances if the bank partnership changes.
- Get the minimum commitment on paper before the rate discussion. Ask what counts toward it, whether unused commitment carries forward, what happens at renewal, and what the termination terms are — none of which is published.
- Price your actual rail mix. Usage is charged per rail, so a quote is comparable only if the split between ACH, wires, RTP and FedNow, push-to-card and stablecoins is fixed first. Treat "coming soon" rails such as SWIFT as absent until a date is contractual.
- Test reconciliation against your ugliest case, not your happy path. Returns, reversals, partial postings, same-day cut-offs and multi-bank sweeps are where this product either earns its fee or does not. Run historical exceptions through a sandbox, and settle how the ledger relates to your general ledger and how you would extract it.
Capability assessment
Every company profiled on this site is assessed against the same eighteen dimensions, so the profiles can be read against one another. Each rating carries one sentence of evidence. There is no score out of ten, because a score is not defensible and a sentence is.
Core strength means a primary, differentiating capability. Supported means genuinely offered and documented, but not a differentiator. Limited means partial, geographically restricted, gated behind an enterprise tier, or delivered through a third party. Not offered means what it says. Unclear means the company markets the capability but does not document it well enough to judge — which is itself a finding.
Who Modern Treasury suits
- Companies that move large volumes of money over bank rails on their own behalf — lenders, payroll providers, insurers, title and escrow, marketplaces — and need initiation, approval controls, a ledger and reconciliation rather than card acceptance.
- Businesses with existing relationships at multiple banks that want one integration across them instead of maintaining a separate file-based or proprietary connection per bank.
- Engineering teams that want a documented API and a double-entry ledger as the system of record for balances, rather than building ledgering in-house alongside bank integrations.
- Companies that need real-time rails specifically: Modern Treasury is FedNow-certified for credit transfers and Request for Payment as of July 2026 and reports the majority of its PSP volume already on real-time rails.
- Digital asset and stablecoin businesses that need fiat and stablecoin movement through one interface — Anchorage Digital is a named customer.
Who Modern Treasury is a poor fit for
- Any merchant whose need is card acceptance. Modern Treasury does not acquire card transactions, does not underwrite merchants and sells no checkout, terminal or point-of-sale product; its card capability is limited to push-to-card payouts.
- Low-volume or seasonal users. Modern Treasury's published pricing page states that annual terms apply and that platform and usage fees count toward a single minimum commitment, so the cost floor does not scale down with a quiet quarter.
- Buyers who need to compare cost before engaging sales. Modern Treasury publishes what it charges for but not what it charges; it states that exact pricing depends on volume, rails used and account structure.
- Businesses needing local payment rails outside the United States. Modern Treasury's rail list is US-centric — ACH, domestic wires, RTP, FedNow, checks — with SWIFT still listed as coming soon as of July 2026 and no marketed coverage of SEPA, Faster Payments, UPI, PIX or similar domestic schemes.
- Organisations that need public evidence of counterparty scale. Modern Treasury is a private venture-backed company that does not publish revenue, headcount or current payment volume; the last self-published volume figure is from its October 2021 Series C announcement.
- Teams whose requirement is a pure, stable bank-connectivity layer over accounts they own. Modern Treasury has moved toward being a full-stack PSP that manages the banking infrastructure itself, so the product a buyer signs today is on a different trajectory from the 2019-era proposition.
Competitors and alternatives
| Company | Why a business would choose it instead |
|---|---|
| Increase | Direct API access to bank rails with a similarly developer-first posture, for teams that want fewer abstraction layers between them and the Fed. |
| Column | A nationally chartered bank with its own API, so the customer gets rails and the bank charter from one counterparty rather than software over someone else's bank. |
| Dwolla | Longer-established ACH and RTP API for companies whose need is bank transfers alone, without a ledger or multi-bank operations layer. |
| Orum | Focuses on intelligent routing and instant settlement across rails, for companies whose problem is payment speed rather than reconciliation. |
| Treasury Prime | Bank-fintech middleware that brokers the bank relationship itself, for companies that do not already have one. |
| Moov | Combines bank rails with card acceptance and payment facilitation, for platforms that need both cards and ACH from one vendor. |
| Stripe | For a company whose money movement is fundamentally card-based, Stripe covers acquiring, payouts and treasury in one place — something Modern Treasury does not attempt. |
Modern Treasury — frequently asked questions
Is Modern Treasury a bank?
No. Modern Treasury is software. In its original model the customer holds accounts at its own banks and Modern Treasury supplies connectivity, payment initiation, approval workflows, a double-entry ledger and reconciliation, while the bank holds the funds. Since 2025 it has also offered a payment service provider product with managed payment accounts and program management, but it holds no banking charter itself.
Does Modern Treasury process credit cards?
Not for acceptance. Modern Treasury is built around bank rails — ACH, wires, RTP, FedNow, checks and stablecoins — and its only card capability is push-to-card payouts. It does not underwrite merchants for card acceptance and sells no checkout, gateway or point-of-sale product, so a business whose need is taking card payments would have to use a separate acquirer or processor.
What is payment operations?
Payment operations is the work that surrounds a payment once the decision to pay has been made: initiating it on the right rail, routing internal approvals, recording it in a ledger, tracking status and returns, and reconciling bank activity against what the business expected. Modern Treasury coined the term and markets the category. At companies without dedicated software, the same work is typically done in spreadsheets and bank portals.
How much does Modern Treasury cost?
Modern Treasury publishes the components of its pricing but not the prices. The three components are platform access, payment usage charged per rail, and accounts and compliance covering KYB, KYC and ongoing transaction monitoring. Terms are annual and usage-based with a single minimum commitment that platform and usage fees both count toward, and the company states that exact pricing depends on volume, rails used and account structure. No rate card is published and early-termination terms are not disclosed.
What payment rails does Modern Treasury support?
As of July 2026: ACH and same-day ACH, domestic wires, RTP, FedNow, checks, push-to-card, stablecoins and global USD accounts, with SWIFT listed as coming soon. Modern Treasury completed FedNow Service certification on 6 July 2026 for credit transfers in both directions and for Request for Payment, connecting through the Federal Reserve's FedLine Advantage. It does not market coverage of non-US domestic rails such as SEPA, Faster Payments, UPI or PIX.
Who uses Modern Treasury?
Customers named on Modern Treasury's own site include Navan, Procore, RealPage, Gusto, Robinhood, GoFundMe, Bilt, Anchorage Digital, AvidXchange, DriveWealth, ClassPass, Stewart Title, Capchase, Parafin and Masterworks. The pattern is companies that move large volumes of money over bank rails on their own behalf — lending, payroll, insurance, real estate and title, marketplaces and digital assets — rather than merchants selling to consumers by card.
How much payment volume does Modern Treasury process?
The company does not publish current volume. The most recent figure it has disclosed is over $400bn processed cumulatively, given in its December 2025 announcement of the Beam acquisition. Before that, its October 2021 Series C announcement cited over $2bn a month. It also reported that 73% of volume through its payment service provider product in May 2026 moved over real-time rails. All of these are self-reported and Modern Treasury, being private, files no financials.
