Banking as a Service (BaaS) providers let a fintech, software platform or brand offer bank accounts, cards and payments without holding its own bank charter. The provider supplies the APIs, and a partner bank holds the license and the funds. Choosing one affects your launch speed, compliance workload, bank partner risk and unit economics. This guide compares ten widely used Banking as a Service providers in the USA so you can match one to your product. If you are also weighing payment infrastructure, see our overview of payment providers.
Quick answer
- All-in-one launch for fintechs and platforms: Unit
- Multi-bank flexibility: Treasury Prime or Synctera
- Direct access to a chartered bank’s APIs: Column or Lead Bank
- Embedded accounts for platforms and marketplaces: Stripe Treasury
- Card issuing and processing: Marqeta or Galileo
- Established sponsor bank with fintech programs: Cross River
- Developer-first banking API: Increase
“Top” here means a strong fit for a defined need based on published positioning and industry coverage. It is not a guarantee of performance for your business.
What Banking as a Service means
BaaS has three layers. The brand owns the customer experience. A middleware platform provides APIs, ledgers, KYC orchestration and card programs. A sponsor bank holds the charter, FDIC-insured deposits and regulatory responsibility. Some providers, such as Unit and Synctera, sit in the middleware layer. Others, such as Column and Lead Bank, are chartered banks that expose their own APIs. Payment gateways play a different role, so read our guide on how a payment gateway works to see where card acceptance fits.

The top 10 Banking as a Service providers in the USA
1. Unit: best for an all-in-one BaaS launch
Unit is a middleware platform that bundles accounts, cards, payments and compliance workflows behind one API, connecting your product to a partner bank.
- Limits: You depend on both Unit and its partner bank, so review both relationships and contract terms
- Suits: Fintechs and software platforms adding banking features
2. Treasury Prime: best for multi-bank flexibility
Treasury Prime lets fintechs work with a network of sponsor banks through one integration. That can reduce single-bank dependence and give you options if a bank partner changes course.
- Limits: Costs and bank availability vary by program, so request a written proposal
- Suits: Fintechs that want bank optionality and a managed compliance layer
3. Synctera: best for fintechs and community banks
Synctera provides BaaS infrastructure and compliance tooling for fintechs and for banks building sponsor programs. Its position between both sides suits teams that want strong oversight features.
- Limits: Bank partner options depend on current program availability
- Suits: Fintech startups and community banks building partner programs
4. Column: best for direct access to a chartered bank
Column is a chartered bank that built its own API stack instead of reselling a middleware layer. Owning the stack can simplify the structure for fintechs that want a direct bank relationship.

5. Lead Bank: best for bank-owned fintech infrastructure
Lead Bank is a chartered bank that works directly with fintech companies and exposes modern APIs rather than relying on a separate middleware company.

- Suits: Fintechs seeking a direct sponsor bank relationship
6. Stripe Treasury: best for platforms and marketplaces
Stripe Treasury lets platforms embed financial accounts and money movement alongside their existing Stripe payments setup. It focuses on treasury and money movement rather than a full consumer banking product.
- Limits: Best fit for existing platform flows, not a standalone neobank build
- Suits: SaaS platforms, marketplaces and payout-heavy businesses
7. Marqeta: best for modern card issuing
Marqeta provides a card issuing platform that lets businesses create and manage physical, virtual and tokenized cards through APIs.
- Limits: It covers card programs, so you may need separate account and ledger infrastructure
- Suits: Expense management, fintech and embedded card programs
8. Galileo: best for card and payments programs
Galileo offers card issuing and payments processing infrastructure used by neobanks and fintechs building card-led products.
- Limits: Account features may need to be paired with other providers
- Suits: Neobanks and card-first fintechs
9. Cross River: best for an established fintech sponsor bank
Cross River is a bank that partners with fintech and technology companies on lending, payments and card programs. Like other sponsor banks, it has faced regulatory scrutiny, so review current enforcement actions before committing.
- Limits: Regulatory history and program oversight standards should be part of your due diligence
- Suits: Fintech programs that want an experienced bank partner
10. Increase: best for developer-led banking APIs
Increase offers an API platform for banking and money movement aimed at engineering teams that want to build directly on bank infrastructure.
- Limits: Confirm bank partners, supported programs and onboarding requirements
- Suits: Developer-led fintechs and technical product teams
BaaS models and pricing structures
- Middleware plus sponsor bank: A platform provides the APIs and a partner bank holds the funds. This offers speed but adds more parties to the contract.
- Chartered bank with APIs: The bank and the technology sit together. This can simplify the structure but ties you to one bank.
- Payments-first or card-first platforms: Specialized for treasury, money movement or issuing. These often need to be combined with other infrastructure.
BaaS pricing is rarely published. Expect platform fees, per-account or per-transaction fees, and interchange sharing, all negotiated. Always request a written fee schedule.

How to choose the right BaaS provider
- Define your product. Accounts, cards, payments or all three.
- Check the bank partner. Review its regulatory standing and how many programs it supports.
- Assess who handles compliance. Clarify responsibility for KYC, AML and ongoing monitoring.
- Ask about funds flow and reconciliation. Understand how ledgers are kept and reported.
- Plan for continuity. Look for contract terms that cover bank changes and wind-down.
- Model total cost. Include platform, per-transaction, card and compliance costs.
Common mistakes
- Choosing on speed to launch alone
- Not reviewing the sponsor bank’s regulatory history
- Unclear responsibility for compliance between you, the provider and the bank
- Ignoring reconciliation and ledger transparency
- Having no plan if the bank partner exits the program
Need a payment solution for a regulated or higher-risk business?
Some industries face stricter underwriting from banks and processors. In that case, review merchant account providers built for specialized needs.
Verdict
There is no single best Banking as a Service provider. Middleware platforms suit speed and flexibility, chartered banks with APIs suit teams that want a direct relationship, and card platforms suit card-led products. Shortlist two or three, request written proposals, and review each bank partner’s regulatory standing before you commit.
