The Sanson Composable Banking Platform
A modular banking architecture that connects financial technology capabilities through APIs, integration and intelligent services — designed for progressive modernization.
A composable banking platform allows financial institutions to assemble banking capabilities from modular services rather than relying on a single monolithic technology stack. Sanson Group combines modular fintech capabilities, API connectivity, integration and AI to support progressive banking modernization.
What Is a Composable Banking Platform?
Modular Services
Independent, interchangeable services for each banking capability, deployable on their own timeline.
API Connectivity
Standardized APIs connect every module to the existing core and surrounding systems.
Interoperability
Modules are designed to work together and with third-party systems through common interfaces.
Progressive Modernization
Institutions adopt and expand capabilities incrementally, rather than all at once.
Continuous Evolution
Each capability can be updated independently as needs and regulation change.
Composable banking is an architectural approach in which independent, interchangeable fintech modules — for payments, lending, RegTech, AI and more — connect to a bank's existing core through standardized APIs. This allows financial institutions to modernize individual capabilities progressively, rather than replacing their entire technology stack at once.
What is a composable banking platform?
A composable banking platform is an architecture in which financial institutions assemble banking capabilities from modular, interchangeable services connected through APIs and integration layers. Instead of replacing the entire technology stack, institutions can introduce, replace or expand individual capabilities as their modernization priorities evolve.
How the Platform Connects, Layer by Layer
Open each layer to see how it fits into the full Sanson architecture — from the customer through to core systems and data.
01 — CUSTOMERCustomerEnd customers and institutional users
Retail and institutional customers who interact with the bank through digital and physical channels.
02 — CHANNELSDigital ChannelsWeb, mobile, branch and partner experiences
Consistent digital banking experiences across web, mobile and branch, connected to the capabilities beneath them.
03 — CAPABILITIESSanson CapabilitiesSix modular services
The modular services that make up the platform, each adoptable independently:
04 — ORCHESTRATIONOrchestrationCoordinated workflows across modules and legacy systems
Coordinates workflows that span multiple capabilities and legacy systems, so modules work together rather than in isolation.
05 — APISAPIsStandardized connectivity
Standardized APIs connect capabilities, orchestration and the core, replacing custom point-to-point integration.
06 — CORECore SystemsThe institution's existing infrastructure
The bank's existing core banking infrastructure remains in place — the platform connects to it rather than replacing it.
07 — DATAPayments / DataSettlement rails and the data layer
Underpins transactions and decisions across every layer above it, from settlement to analytics.
The Integration Layer
API Management
Standardized, managed APIs govern how modules connect to each other and the core.
OpenAPI Specification ↗Orchestration
Coordinates multi-step workflows that span several capabilities and systems.
Middleware
Bridges communication between modern services and existing infrastructure.
Data Connectivity
Moves and synchronizes data consistently across capabilities and the core.
Existing Core Integration
Connects to the institution's current core banking system without requiring its replacement.
AI & Intelligence
Intelligence operates across onboarding, fraud, compliance, credit, lending, service and operations — embedded within capabilities rather than added as a separate layer.
Explore AI & IntelligenceDesigned for Progressive Modernization
Start With a Priority Capability
Begin with the capability that matters most to the institution's current priorities.
Integrate With Existing Systems
Connect the new capability to the existing core and surrounding infrastructure.
Expand the Architecture
Add further capabilities as priorities, budgets and readiness allow.
Evolve Over Time
Continue refining and extending the architecture as needs and regulation change.
Architecture Principles
Modularity
Capabilities are independent and interchangeable by design.
Interoperability
Modules and existing systems communicate through common, standardized interfaces.
Security
Security considerations are built into the platform's connectivity and data layers.
Governance
Clear oversight for how capabilities are deployed, monitored and changed.
Observability
Visibility into how modules and workflows are performing across the architecture.
Scalability
Capabilities are designed to scale independently as usage grows.
AI Governance
Oversight and explainability for how embedded intelligence makes decisions.
What the Platform Enables
Faster Capability Evolution
Update or extend individual capabilities without a system-wide release cycle.
Better Integration Flexibility
Connect new and existing systems through standardized APIs rather than custom integration work.
More Targeted Modernization
Direct investment toward the capabilities that matter most, rather than the whole stack at once.
New Digital Experiences
Build new customer and operational experiences on top of modular capabilities.
Intelligent Operations
Apply embedded AI across capabilities to support day-to-day banking operations.
