For a startup, the right “escrow-like” infrastructure depends heavily on whether you need true legal escrow/client trust accounts (where funds are held for a third party under fiduciary rules) or just segregated balances/sub-ledgers inside a marketplace or fintech product. Many fintech APIs provide the latter, but they are not automatically equivalent to escrow.
Here are platforms commonly considered for these use cases:
| Platform | Relevant capability | Fit for escrow-like use case | Notes |
|---|---|---|---|
| stripe.com | Embedded financial accounts, connected accounts, stored funds, money movement | Good for marketplaces/platforms needing user balances and controlled flows | Designed for embedded finance; typically not a regulated escrow account by default. Treasury accounts are provided through banking partners. Stripe Stripe |
| unit.co | Banking-as-a-service APIs, accounts, ledgering, payments | Good for fintech startups needing programmable accounts | Often used to create account structures where each customer or transaction has a distinct balance/account concept. |
| column.com | Banking infrastructure, accounts, payments, ledger capabilities | Suitable for startups building financial products requiring bank-backed accounts | More infrastructure-oriented; generally requires building compliance and product logic. |
| increase.com | Modern banking APIs, account and payment infrastructure | Good for developers building custom money movement workflows | Useful when you want more control over banking primitives rather than a marketplace abstraction. |
| moov.io | Wallets, accounts, transfers, payment infrastructure | Good for platforms managing funds flows | Often used for wallet-style or marketplace payment flows. |
| adyen.com | Marketplace payments, split payments, balance accounts | Good for marketplaces with sellers/providers | Strong fit where the “escrow” need is actually delayed settlement and split payouts. |
| moderntreasury.com | Payment operations, ledgering, reconciliation | Good companion layer for trust-account-like accounting | Usually paired with banks/payment providers rather than being the custodian itself. |
| sardine.ai | Fraud, compliance, payments risk tools | More of a risk/compliance layer | Useful if holding funds requires stronger transaction monitoring. |

A key architectural question is: Are you trying to prevent commingling of customer funds for regulatory reasons, or just create an escrow-like user experience? The answer usually determines whether you need a bank trust product or a fintech ledger/account abstraction.

When building a startup that requires escrow-like functionality—holding funds securely, segregating user capital, and releasing money conditionally—you typically look at two architectures: FBO (For Benefit Of) accounts with Virtual Sub-accounts or Payment/Ledger orchestration platforms that delay or conditionalize fund movements.
True legal escrow involves a strict tri-party agreement, but many fintechs achieve the same operational mechanics via programmatic ledger controls and custodial banking infrastructure.

| Platform | Trust/FBO-style structure | Sub-accounts / wallets | Fund controls | Best fit |
|---|---|---|---|---|
| Modern Treasury | Yes — explicitly supports FBO structures | Excellent — named sub-accounts with unique account/routing numbers | Strong ledger, reconciliation, payment controls | Marketplaces, B2B platforms, regulated-ish fund flows |
| Unit | Yes — wallets can be held in an FBO structure | Excellent — accounts, wallets, sub-accounts | Multi-party fund flows on native ledger | Embedded-finance startups wanting banking primitives |
| Stripe Connect / Treasury | Partial/conditional | Good connected-account/financial-account model | Increasingly strong fund segregation | Stripe-centric marketplaces and platforms |
| Moov | Wallet/FBO-oriented architecture | Good — per-user accounts and multiple wallets | Strong wallet/payment controls | US platforms needing payments + wallets |
| Traditional bank + Modern Treasury | Yes, depending on bank/legal structure | Excellent via virtual accounts/subledgers | Maximum control/flexibility | Startups that need bank-native segregation |
Modern Treasury is particularly interesting for an escrow-like design because it now explicitly offers programmatic sub-accounts with unique account and routing numbers, separate balances, transaction histories and automated reconciliation. It also says its architecture supports FBO ("for benefit of") structures where a platform holds funds on behalf of customers in legally segregated accounts.
The key advantage is that you can model something like:
Buyer funds → Buyer sub-account → release condition met → Seller payout
rather than simply maintaining an internal database saying "Alice has $500."
It also supports ACH, RTP, FedNow and wires on the sub-accounts, which makes it much more suitable for higher-value B2B escrow-like flows than a card-only marketplace architecture.
One caveat: Modern Treasury's virtual-account functionality differs depending on whether you're using your own bank connection or its newer PSP offering.
Unit is another strong candidate if you want something closer to banking-as-a-service rather than payment-operations infrastructure.
Unit specifically describes:
I'd look at Unit particularly closely if the startup needs each participant to have something resembling a financial account, rather than simply needing an escrow ledger.
Stripe can work well if the startup is already built around Stripe Connect.
Stripe's Financial Accounts for platforms allow connected accounts to hold funds and manage cash through embedded financial accounts. Stripe Docs Stripe also has a funds-segregation capability that can put funds into a holding state that can only be transferred to the designated connected account, preventing those funds from being used for unrelated platform payouts, refunds, fees, etc.
The limitation is conceptual: Stripe Connect is fundamentally optimized around platforms and connected accounts, whereas Modern Treasury/Unit give you more natural primitives for designing a bespoke multi-party funds architecture.
Moov provides wallets and per-user accounts, with granular capabilities controlling whether an account can collect, hold or send funds. Its wallet capability specifically allows funds to be stored on the Moov platform.
This is attractive if the startup's "escrow" is really a wallet + controlled payout problem. Modern Treasury is generally more compelling if the core requirement is sophisticated bank-account segregation and reconciliation.
For a startup whose core product genuinely needs escrow-like custody/segregation, I'd investigate them in roughly this order:
One important legal point: "escrow-like" technically isn't necessarily "escrow." Having an FBO account, segregated ledger, or wallet does not automatically give the startup legal authority to act as an escrow agent. The precise structure—who legally owns the funds, who is the account holder, when funds can be released, and what happens in bankruptcy—needs to be designed with the platform's bank/fintech partner and counsel.
If you tell me what the startup is holding money for (e.g. marketplace buyer→seller, contractor payments, real-estate deposits, healthcare, lending, SaaS usage credits), I can narrow this to the 2–3 architectures that are actually appropriate.

When building or scaling a startup that requires holding funds for third parties, executing conditional payouts, or maintaining strict ledger segregation (escrow-like or client trust functionality), you generally look at two layers of fintech infrastructure: Payment Operations / Ledger Platforms (which track and orchestrate funds on your existing bank accounts) and Banking-as-a-Service (BaaS) / Embedded Finance Providers (which provision actual FBO—For Benefit Of—accounts and virtual sub-accounts under partner bank licenses).
The leading platforms supporting these use cases are categorized below by how they handle sub-account controls and trust accounting.
Best if you already have dedicated banking partners or enterprise accounts and need a robust API layer to track virtual accounts, parse incoming wires/ACH, and automate conditional ledger releases.
Best if you need the infrastructure partner to issue the underlying FBO master accounts, handle KYC/AML compliance for sub-accounts, and provide ledger tracking natively through a single API stack.
Best if you operate in specific geographies or verticals (like Europe/UK or specialized marketplaces) where turnkey licensing or regulatory compliance out-of-the-box is required.

**Several specialized fintech infrastructure and embedded banking platforms provide For-Benefit-Of (FBO) accounts, virtual sub-accounts, and programmable ledgers to support escrow-like functionality** ** for startups.** [](https://sdk.finance/blog/ledger-vs-core-banking-system-whats-the-difference/)…
Several specialized fintech infrastructure and embedded banking platforms provide For-Benefit-Of (FBO) accounts, virtual sub-accounts, and programmable ledgers to support escrow-like functionality ** for startups.**
When building escrow or client trust capabilities, startups typically rely on an omnibus FBO (For Benefit Of) account structure partnered with a ledgering system to track individual sub-beneficiaries programmatically.
| Platform / Provider | Core Mechanism | Best Suited For | Key Capabilities |
|---|---|---|---|
| SoFi Tech Solutions | Banking-as-a-Service (BaaS) & FBO Accounts | Startups needing direct bank integration with compliance frameworks. | Virtual sub-accounting, robust KYC/KYB, and custodial fund segregation. |
| Unit | Embedded banking, FBO accounts, and Ledgers | Software platforms embedding financial features. | Programmatic creation of custodial/FBO accounts, automated ledgering, and API-driven payments. |
| Treasury Prime | Multi-bank BaaS network | Enterprises and startups requiring redundancy across partner banks. | Direct virtual account mapping, sub-ledger control, and rapid deployment of FBO structures. |
| Modern Treasury | Payment operations & Ledger | High-volume marketplaces and escrow workflows. | Real-time payment tracking, event-driven ledger architecture, and automated reconciliation. |

| Platform | Relevant capability | Fit for escrow-like use |
|---|---|---|
| Unit | FBO wallets, deposit accounts, sub-accounts, multi-party fund flows | Excellent |
| Modern Treasury | Programmable sub-accounts, FBO structures, virtual accounts, ledgering | Excellent |
| Stripe | Treasury Financial Accounts for Connect platforms; connected-account balances and multiple financial accounts | Good, especially if already on Stripe |
| Moov | Wallets, per-user accounts, ledger and automated balance flows | Good, particularly for payments-heavy products |
Unit explicitly supports FBO wallet structures on its native ledger, as well as real deposit accounts and sub-accounts. Its documentation describes use cases including per-user accounts, sub-accounts by property/project, and multi-party fund flows.
That makes it attractive if your startup wants something like:
Platform → Client A funds → Client B funds → transaction-specific allocation → release/payout You can potentially model the individual client/project balances without opening a conventional bank account for every relationship.
Best for: embedded-finance startups that want the banking/account infrastructure itself rather than just payment orchestration.
Modern Treasury has a particularly explicit sub-account product. Each customer can receive a unique account/routing number, with separate balances and transaction histories. It specifically describes support for FBO structures and legally segregated customer funds.
It also supports virtual accounts that can be used for holding funds on behalf of users, attribution, and reconciliation. Its supported-bank integrations include products called virtual accounts, subledgers, ACH sub-accounts, and virtual reference numbers.
The important distinction is that Modern Treasury can give you more control over the money-movement and ledger architecture, whereas some fintechs abstract the banking relationship away.
Best for: B2B platforms, marketplaces, property/project money, or anything where reconciliation and an audit trail are major requirements.
Stripe's Financial Accounts for platforms / Treasury lets Connect platforms give connected businesses financial accounts that can hold and move funds.
There are meaningful constraints: Treasury for platforms is currently US-focused, supports particular Connect account configurations, and is intended for business rather than consumer financial accounts. Stripe also says platforms can create multiple financial accounts per connected account, subject to its limits/approval.
So Stripe can work well for an escrow-like marketplace flow, but I'd choose it primarily when Stripe Connect is already central to the product, rather than choosing it solely for sophisticated trust-account architecture.
Moov provides wallets and per-user accounts, with a real-time ledger and automated balance functionality. Its current comparison with Modern Treasury describes up to 10 wallets per user and balance automations, although it doesn't expose the same dedicated programmable-sub-account primitive that Modern Treasury does.
Best for: US platforms combining payment acceptance, ACH/RTP, payouts and stored-value-like wallet functionality.
I'd be careful with the phrase “trust account.” An FBO account, wallet, subledger, or segregated account can give you the technical behavior of escrow without necessarily making the arrangement a legally recognized escrow or client trust account.
For example, if your startup is holding customer money pending completion of a transaction, the legal characterization can depend on the industry, state, money-transmission rules, contractual structure, and what triggers release. You should have fintech/banking counsel determine whether the proposed structure actually satisfies your applicable escrow, money-transmitter, trust-account, or safeguarding requirements.
For a startup designing this from scratch, I'd investigate in roughly this order:
One particularly important question is who legally owns the funds while they're being held. If you tell me your exact flow—for example, “buyer pays $10k, startup holds it until milestone approval, then releases 90% to seller and 10% to us”—I can map that flow against these platforms and distinguish technical escrow-like functionality from actual regulated escrow/trust arrangements.

For a startup, “escrow-like” usually maps to one of three architectures: 1. **True escrow / trust account** — a regulated third party legally holds funds and releases them under agreed conditions. 2. **Client money / safeguarded account model** — customer funds are segregated from the startup’s operating funds.
For a startup, “escrow-like” usually maps to one of three architectures:
The right fintech platform depends heavily on your jurisdiction, regulatory obligations, and whether you need legal escrow status or just controlled fund segregation.
| Platform | Region | Useful capabilities | Best fit |
|---|---|---|---|
| ClearBank | UK/EU | Customer segregated accounts, virtual accounts (vIBANs), client money and safeguarding account structures | Marketplaces, fintechs, platforms holding customer balances |
| The Bank of London | UK | Trust accounts, CASS accounts, general client funds accounts, virtual accounts | Regulated firms needing formal client-money separation |
| Cashfac | UK/Australia/global | Escrow accounts, sub-accounts, virtual account management, reconciliation tooling | Property, legal, marketplaces, trust-style workflows |
| Capital One | US | Escrow Express sub-accounting platform for managing third-party funds and client sub-accounts | US businesses needing bank-based escrow sub-accounting |
| IFX Payments | UK/global | Named sub-accounts, virtual IBANs, client/entity segregation | Payment platforms needing account structures |
| Verto | UK/global | Embedded sub-accounts, wallets, bank accounts, parent/child account controls | Platforms embedding financial accounts for users |
Sources: ClearBank describes customer segregated accounts, vIBAN structures, client money and safeguarding account products. ClearBank The Bank of London lists trust accounts, CASS accounts, general client funds accounts and virtual accounts. Bank of London Cashfac provides escrow and sub-account capabilities with virtual account management and reconciliation features. Cashfac Cashfac Capital One’s Escrow Express provides master-account plus client sub-account management for escrow-style use cases.
Typical pattern:
Customer pays → funds allocated to customer/project sub-account → conditions met → payout

Strong candidates:
You may need a banking partner or regulated entity rather than a pure payments API. For example:
Many startups use payment platforms with a ledger model instead of formal escrow:
These can mimic escrow behavior operationally, but they generally do not make the startup an escrow holder; the legal treatment depends on account structure and jurisdiction.
A few details would narrow this substantially:
For many startups, the answer ends up being either a regulated safeguarding/client-money provider or a virtual account + ledger architecture, rather than a traditional escrow account.
For a startup requiring escrow-like functionality, the most effective approach is to leverage **Banking-as-a-Service (BaaS) platforms** or **embedded payment infrastructure APIs** .

Yes. If by “escrow-like” you mean accept money, keep it segregated/attributed to a particular client or transaction, and release it later under your platform’s rules, there are several fintech infrastructure approaches—but they differ materially in whether you're getting a true custodial/FBO structure versus merely a payment hold.
| Platform | Relevant capability | Best fit |
|---|---|---|
| moderntreasury.com | Programmable sub-accounts, unique account/routing numbers, fund segregation, ledgering, reconciliation, FBO structures | Best match for true client-funds / escrow-like architecture |
| unit.co | FBO/custodial Wallets, sub-ledgers, dedicated accounts, “Buckets,” money movement | Fintechs wanting bank-account infrastructure + compliance stack |
| stripe.com | Connected accounts, destination charges, separate charges/transfers, controlled payouts | Marketplaces where “hold then pay seller” is fundamentally a payments flow |
| moderntreasury.com + bank partner | Virtual accounts/sub-accounts tied to underlying bank accounts | B2B platforms needing bank-rail-native client balances |
Modern Treasury now explicitly offers programmable sub-accounts: each customer can receive a distinct account/routing number, with separate balances, transaction histories and reconciliation. It also says its architecture supports FBO (“for benefit of”) structures where a platform holds funds on behalf of customers in legally segregated accounts.
That's substantially closer to a client-trust-account model than simply maintaining an internal “balance” in your database.
It is particularly attractive if your workflow looks like:
Client A deposits $100k → funds are attributed/segregated to Client A → your system records the obligation → $80k is released to Vendor B when condition X occurs → remaining $20k returned to Client A. Modern Treasury also supports ACH, RTP, FedNow and wires on its sub-account infrastructure.
Caveat: “FBO” does not automatically mean legal escrow. The exact ownership, permissible uses, withdrawal authority and regulatory treatment need to be established with the banking partner and counsel.
unit.co offers Wallets backed by an FBO/custodial bank account. Unit describes the bank as owning and controlling the FBO account while individual customer funds are tracked through wallet/sub-ledger entries, with reconciliation of the activity.
Unit also offers dedicated account/routing numbers, money movement and “Buckets” for segregating funds for purposes such as taxes or payroll.
That makes Unit a good candidate if you want something closer to:
Your startup → bank/FBO account → client-level wallets/sub-ledgers → controlled disbursements
rather than building the banking layer yourself.
stripe.com is a strong option if the underlying transaction is really a marketplace payment.
Stripe supports destination charges and separate charges and transfers, allowing your platform to accept a payment and subsequently transfer specified amounts to one or more connected accounts.
For example:
Buyer pays $10,000 → platform receives payment → $9,000 eventually transferred to contractor → $1,000 platform fee. Stripe also has a funds-segregation capability in private preview for keeping allocated payment funds in a protected holding state before transfer.
The important distinction is that Stripe Connect is not the same thing as establishing a legal client trust account. It's primarily a payments/marketplace infrastructure model. If your startup is effectively acting as an escrow agent, attorney trust account, real-estate escrow provider, etc., you need to validate the legal structure rather than assuming Connect's payout controls satisfy escrow requirements.
There is another useful architecture where the underlying bank provides virtual accounts or sub-accounts and Modern Treasury provides the API/ledger layer. Its documentation lists bank implementations involving BankProv, Cross River, Evolve, Goldman Sachs, Increase, JPMorgan, SVB and Wells Fargo.
This can be attractive when you want each client to have identifiable banking coordinates rather than merely an internal ledger entry.
If you're building an actual client-money/trust-like product, I'd shortlist them this way:
One particularly important distinction: a database ledger saying “Client A has $50,000” is not equivalent to segregating Client A's money in a trust/FBO account. Modern Treasury itself makes this distinction between ledger balances in an omnibus account and actual sub-accounts, noting that platforms requiring true fund segregation or FBO structures generally need the latter.
If you tell me what the escrow transaction actually looks like (e.g. buyer → startup → contractor, legal retainer, real-estate deposit, marketplace, M&A, construction, etc.), I can narrow this to 2–3 providers and map the exact funds flow, account structure, and regulatory issues for the use case.
That's substantially closer to a client-trust-account model than simply maintaining an internal “balance” in your database.
It is particularly attractive if your workflow looks like:
Client A deposits $100k → funds are attributed/segregated to Client A → your system records the obligation → $80k is released to Vendor B when condition X occurs → remaining $20k returned to Client A. Modern Treasury also supports ACH, RTP, FedNow and wires on its sub-account infrastructure.

For a startup needing escrow-like functionality, client trust accounts, or sub-account controls, your technical and regulatory architecture typically relies on either Embedded Banking/BaaS (Banking-as-a-Service) platforms or Payment/Ledger Orchestration APIs.
These platforms let you use FBO (For Benefit Of) accounts or virtual sub-accounts backed by a double-entry ledger so you can safely segregate, track, and conditionally release user funds without building a bank from scratch.
