Embedded finance has a dirty secret
Most “BaaS” is just a deposit pipe.
A brand gets a checking account and a debit card, reconciled by a middleware vendor the bank can’t see into. The moment the brand’s customers want credit, the relationship breaks and gets handed to a different lender on a different system. The bank holds the deposits and the regulatory risk — but captures only the thinnest slice of the customer’s financial life.
A deposit pipe
- A checking account and a debit card
- Reconciled by middleware the bank can’t see into
- Credit breaks off to a different lender
- The bank holds the risk, captures the thinnest slice
A banking network
- Deposits and credit under the brand’s own name
- On the bank’s core, settling to one ledger
- The bank keeps the charter, compliance, and loan book
- The brand gets the experience; the bank gets the economics
The difference between renting out an account number and running a banking network.
Both sides of the balance sheet
Deposits and credit, for every brand.
The deposit side
Five prebuilt program templates that launch in days, not quarters.
Retail Banking
White-label checking + debit for a consumer brand.
Investment Fund
FBO sub-accounts for capital calls and distributions.
Gig Wallet
Instant-issue tokenized wallets and virtual cards.
Marketplace Payments
Per-seller virtual accounts and split payments.
SMB Treasury
Operating + payroll + tax-reserve accounts.
Each clones into a fully editable program. Pick the primitives — DDA, FBO, virtual accounts, escrow, ACH/RTP/wire, debit & virtual cards, tokenized wallets, treasury & yield — set fees and revenue split, then promote draft → configuring → UAT → live.
The credit side
A full credit shelf under the brand’s own name. In the reference build, ShopFlex runs all six side by side.

Powered by Foundry
The credit is real because it’s yours.
Fabric’s credit isn’t originated somewhere else. When a brand’s customer taps “Pay Later” or requests a business line, the application flows into Foundry’s underwriting engine — the same decision gate, policy, and booking path the bank uses for its direct lending — and books a real loan against the real GL, with the same evidence and adverse-action discipline.

The operating system underneath
A true operating system, not a pile of integrations.
Fabric Studio
A visual flow builder where every onboarding journey — KYC, KYB, OFAC, beneficial-owner screening, doc capture, account creation, card issue — is a node graph the bank edits and versions per program.
Per-partner subledger
Every program keeps its own double-entry chart of accounts that reconciles to the core GL, with break detection and a transaction-signature audit. Deposits and embedded loans both land here.
Built-in compliance
KYB findings wire into the bank’s BSA/Fusion Center. Configurable rules — velocity, large-transaction, dormancy, FDIC-coverage, counterparty — can alert, freeze, sweep, or block. Partner-customizable, bank-overridable.
Deposit protection
ICS / repo sweep networks keep program deposits insured and yield-bearing, with coverage tracked per fund and per partner.
Developer & ops console
Partners integrate via API; the bank watches API health, onboarding pipelines, approval SLAs, and end-user (DDA) activity from one console.
Approvals, messaging & AI insights
Approval chains, partner messaging, and AI-surfaced insights round out the operating layer — so the bank says yes without drowning in risk.
The proof point
Offering Banking-as-a-Service, or operating a banking network.
Because Fabric runs on the core — and routes its credit through Foundry — a brand’s entire financial relationship lives in one place the bank fully controls.
One ledger
Deposits, cards, BNPL, lines of credit, the compliance record, and the revenue split — all settle to one ledger the bank controls.
One underwriting standard
Embedded credit runs on Foundry — the same decision gate, policy, and booking path as the bank’s direct lending.
One compliance record
KYB and program rules feed the bank’s Fusion Center, so the regulatory posture is the bank’s, not a vendor’s.
Both sides of the economics
The brand owns the experience. The bank owns the deposits, the loan book, and the risk — never losing sight of either.
Deposits and credit. One ledger. Your charter.
Fabric runs on Nucleus BankOS, and routes its credit through Foundry — so brands launch under their own name while you keep the charter, the compliance posture, and both sides of the balance sheet.
