explore the possibilities

The only impossible is what you haven't built yet.

Legacy infrastructure holds banks back. OpenCoreOS transforms your core from a costly bottleneck into a catalyst for growth, giving you the freedom and agility to build the future of finance.

Design and launch any deposit product in weeks, not years. Our composable, domain-driven architecture frees your business logic from the core, giving you the speed to capture new markets and adapt to customer needs instantly.

core components

A modern core for the Digital Finance & AI era.

An entirely real-time, composable platform for innovation without constraints. Its powerful components work in harmony or can be adopted independently to upgrade your existing stack.

Ledger

The single source of truth for your entire asset portfolio. Seamlessly manage traditional fiat and modern digital assets on one immutable ledger, with guaranteed mathematical precision that eliminates reconciliation errors.

Interest engine

Power any interest-bearing product you can design. This flexible engine executes even the most complex tiered rates and promotional offers with perfect accuracy, allowing you to ship innovative products faster.

Reconciliation engine

Automate even the most complex reconciliation tasks. Our powerful event-driven engine features a configurable rules engine to define any matching logic without code—from simple one-to-one to complex many-to-many scenarios—with a complete audit trail for total compliance.

Compliance rules engine

Turn complex regulations into machine-enforceable rules that are applied automatically. Our AI co-pilot helps translate dense regulatory text into a precise, auditable policy, ensuring you can prove compliance at every moment.

MARS. Infra that runs itself. OpenCoreOS was engineered for a zero-downtime world. Our AI-native infrastructure doesn't just alert you to problems—it anticipates them, resolves them automatically, and learns from every event to become progressively more resilient.

Predict, fix, and prevent

Go from reactive to proactive. Our platform predicts infrastructure issues before they impact customers, executes automated resolutions, and reports back with a full analysis, all without human intervention.

AI-powered ChatOps

Turn your chat tools into an operational hub. Your team can investigate incidents, approve automated actions, and query system health using natural language in Slack or Teams.

Extensible beyond the core

Extend the umbrella of autonomous operations. Our AI monitoring and resolution capabilities can be configured to cover your entire banking application ecosystem, not just the core.

Immutable audit trail

Trust every action. Every automated decision and resolution is securely recorded, providing a crystal-clear audit trail for compliance and review.

Resilience at scale. OpenCoreOS was engineered to meet the benchmarks of a Tier-1 bank, giving you the tools to scale at a pace that matches your ambitions.
