Mambu

What is Mambu?

Mambu is a SaaS cloud banking platform that gives banks, neobanks, lenders, fintechs, credit unions, and non-financial brands a composable core banking foundation. It sits in the Fintech Infrastructure category because it provides the backend systems used to configure deposits, lending, payments, Islamic banking, Banking as a Service, embedded finance, and Buy Now Pay Later products.

The platform is cloud-native, API-first, and built for institutions that want to launch or modernize financial products without relying on a traditional legacy core. It operates across EMEA, APAC, LATAM, and North America, serving financial services in 65+ countries and powering products used by more than 230 million end users.

Key Features & Services

Composable Core Banking Architecture

The platform uses a composable model, meaning financial institutions can assemble core banking components and connect them with specialist providers. This matters for banks and fintech companies that want more control over their technology stack instead of depending on one vendor for every function.

A composable core can support different product lines, including deposit accounts, loan products, BNPL plans, and embedded banking services. It also helps institutions reduce vendor lock-in because they can connect third-party partners through APIs and change parts of the stack over time.

Cloud-Native Infrastructure

The core banking system was built in the cloud from the start. That makes it different from older banking software that was later moved into hosted environments. The platform supports high availability, global scale, and upgrades that don't require the same level of disruption often associated with legacy core replacement projects.

It guarantees up to a 99.99% uptime SLA, which is an important service-level benchmark for banks, lenders, and digital finance providers running customer-facing products. The company also says it processes more than 500 million API calls per day, a useful indicator of production usage at scale.

API-First Product Configuration

The platform is designed as an API-First Platform, with configuration playing a larger role than custom coding. Financial institutions can set up products, processes, and rules through configurable tools rather than building every product from scratch.

This approach is especially relevant for digital banks, fintech lenders, and Banking as a Service providers that need to test new propositions quickly. The company states that institutions can launch new products up to 80% faster, although actual timelines depend on integration scope, compliance work, partner selection, and internal delivery capacity.

Multi-Cloud Deployment Options

The service is multi-cloud by design and can run on AWS, Google Cloud, or Microsoft Azure. That gives regulated financial institutions more choice when matching cloud architecture to resilience, data residency, procurement, and internal risk requirements.

Multi-cloud support can also help banks avoid becoming too dependent on one cloud provider. For larger institutions, this can be a key point during vendor assessment, especially when internal policies require exit planning or cloud concentration risk controls.

Migration and Modernization Paths

Financial institutions can use several deployment approaches: greenfield launch, progressive modernization, dual-core strategy, or full migration. A greenfield launch can work for a new digital bank or fintech product. A progressive approach may suit an incumbent bank that wants to move one product line or customer segment first.

A dual-core strategy lets an institution run a new core alongside existing systems, which can reduce operational risk during transition. Full migration is the broadest option and usually involves more planning, testing, data movement, and governance. For established banks, the range of options can make modernization more practical than a single all-or-nothing core replacement.

Pricing & Fees

Mambu does not publicly publish standard pricing plans, subscription tiers, setup costs, or usage-based rates. Pricing for cloud core banking platforms is usually handled through direct sales because contract size depends on the institution type, regions, products, deployment model, user volumes, API activity, service levels, and implementation support.

Pricing item	Publicly listed?	Notes
Monthly platform fee	No	Likely quoted based on institution requirements
Setup or implementation fee	No	Scope may vary by migration path and integrations
API usage fees	No	The platform processes 500 million+ API calls per day across customers
Support or SLA fees	No	Up to 99.99% uptime SLA is listed for the cloud banking platform
Partner integration costs	No	Costs may depend on selected vendors from the 450+ partner network

Banks and fintechs evaluating the platform should ask for a pricing model that separates recurring software fees, implementation services, cloud costs, support levels, and any partner charges. Procurement teams should also confirm how fees change with product launches, transaction growth, customer growth, and regional expansion.

Pros and Cons

Pros

• Cloud-native core: Built for cloud deployment from day one rather than adapted from older on-premise banking software.
• High uptime target: Offers up to a 99.99% uptime SLA, which is useful for institutions running always-on financial products.
• Large operating footprint: Supports financial services in 65+ countries across EMEA, APAC, LATAM, and North America.
• Scale indicators: Powers products used by more than 230 million end users and handles more than 500 million API calls per day.
• Multi-cloud choice: Supports AWS, Google Cloud, and Microsoft Azure, giving institutions more options for cloud and resilience planning.
• Partner network: Works with 450+ partners, helping institutions connect specialist tools for payments, compliance, customer experience, analytics, and other functions.
• Security certifications: Lists SOC I, SOC II, and ISO 270007 certifications, which are relevant for enterprise vendor due diligence.
• Flexible migration paths: Supports greenfield, progressive modernization, dual-core, and full migration strategies.

Cons

• No public pricing: Buyers need to contact sales to understand platform fees, implementation costs, and commercial terms.
• Enterprise buying process: The service is aimed at institutions, so evaluation, contracting, risk review, and implementation may take time.
• Not a consumer bank: It does not offer personal accounts, cards, or loans directly to retail users.
• Integration work still matters: API-first architecture reduces some build effort, but banks must still connect partners, data flows, compliance checks, and operational processes.
• Regulatory responsibility stays with clients: The platform is not presented as a deposit-taking bank, so licensed institutions remain responsible for customer compliance, permissions, and supervisory obligations.
• Complex migrations need planning: A full core replacement can still involve data migration, parallel testing, staff training, and change management.

Who Is Mambu Best For?

The platform is best suited to organizations that need a configurable core banking system rather than an off-the-shelf business account or payment gateway. It is mainly a B2B banking technology provider for institutions building financial products at scale.

Banks can use it for core modernization, new digital brands, product launches, or selective migration away from legacy systems. The dual-core and progressive modernization options are particularly relevant for established banks that cannot risk disruption to existing customer accounts.

Neobanks and fintech startups may use the platform to configure deposit, lending, payment, or BNPL products faster than building a core ledger and servicing layer internally. The claim of launching products up to 80% faster will appeal most to teams with clear product requirements and strong implementation partners.

Lenders can use it to build and manage loan products, including digital lending workflows and alternative credit propositions. Credit unions may consider it when they want more flexible product configuration and cloud operations without maintaining a legacy core system.

Non-financial institutions may find it relevant for embedded finance and Banking as a Service programs. A retailer, telecom company, marketplace, or platform business could use a banking infrastructure partner to offer financial products through a licensed financial institution or regulated program structure.

Regulatory treatment depends on the buyer's business model and country. Banks using this type of core in the UK, EU, US, UAE, or other markets typically remain under their existing banking, payment, lending, or e-money regulators, such as the FCA, PRA, ECB, national central banks, US federal or state regulators, or the Central Bank of the UAE where applicable.
