Banking as a Service (BaaS) is now the backbone of embedded finance. With the right API banking platform, any company can launch accounts, cards, and payments inside their product without becoming a bank.
If you’re comparing Banking as a Service companies in 2025, this quick guide gives you an updated snapshot of 10 notable BaaS providers, what they’re best at, and what to keep in mind when choosing a partner.
What Is Banking as a Service (BaaS)?
Banking as a Service lets regulated banks and fintechs expose their infrastructure via APIs so other businesses can offer bank accounts, cards, payments, lending, and wallets directly inside their own apps.
Instead of building a core banking system or getting a banking license, you plug into a BaaS provider or embedded banking platform that handles:
- Regulatory compliance (KYC/AML, licensing, reporting)
- Connections to payment networks and card schemes
- Core ledger, accounts, and transaction processing
This is what powers neobanks, gig-worker cards, in‑app wallets, and branded payment cards you see everywhere.
Top Banking as a Service (BaaS) Providers in 2025
In 2025, BaaS is one of the fastest‑growing segments in fintech:
- Non‑financial brands (retail, marketplaces, SaaS) want to embed finance to boost loyalty and monetization.
- Regulators and open‑banking initiatives are pushing banks to be API‑first.
- More banks, processors, and fintechs are launching BaaS platforms of their own.
This means more choice – but also more complexity. The list below gives a quick, business‑focused view of 10 BaaS providers often considered when planning a fintech or embedded finance product.

How to Choose a BaaS Provider in 2025
Before you sign with any BaaS platform, shortlist providers using a few key criteria:
- Coverage & Licensing
Where are your customers? Pick BaaS providers with licenses and bank partners in those regions (e.g., EU vs US vs UK). - Product Fit
Do you need full banking (accounts + cards + lending) or just card issuing and payments? Avoid over‑buying and under‑using. - Compliance & Security
Check regulatory history, KYC/AML tooling, certifications, and how they handle data protection. Recent failures (like Synapse, Intergiro) show how crucial this is. - Developer Experience
Review API docs, SDKs, sandbox, and support. A good API banking platform saves months of dev time. - Scalability & Cost
Understand pricing (setup, monthly minimums, per‑transaction fees) and whether the platform can handle your growth plans.
