Core offering

Capstone Limited provides orchestration platforms, APIs, and managed services for digital infrastructure, payments, and compliance operations. The company offers modular orchestration layers (Payment Orchestration, Compliance Orchestration, AML Orchestration Backbone) supported by middleware (UNI-RAIL), a developer portal, and managed operations services targeting financial institutions, payment service providers, and enterprises.

Product overview

Capstone is a unified technology orchestration platform combining a cloud-native infrastructure backbone with modular components for payment processing, compliance automation, and developer enablement. The core platform provides Payment Orchestration (routing, reconciliation, ledgering, observability) and Compliance Orchestration (KYC/KYB APIs, pre-built compliance templates, consistent environments) as integrated modules. Developer-facing tools include the Developer Portal with API Reference, SDKs (TypeScript, with Python on roadmap), Webhooks/Events, Quickstarts, and Sandbox/Test Simulators. Supporting services include Managed Operations (tiered L1-L3 casework, training, regulator engagement) and Innovation Teams (specialized pods, co-creation, Build-Operate-Transfer). The Qualified Partner Program offers no upfront cost value-aligned commercial terms. Key technology products include UNI-RAIL middleware (exposing OpenAPI over legacy cores) and an AML Orchestration Backbone with ISO-20022 alignment and policy-driven routing. All components share unified REST APIs, webhooks, schema-driven data models, and cloud-native architecture with 99.9% uptime targets.

• Jumio: Jumio offers identity verification, KYC/KYB, and AML compliance orchestration APIs. It overlaps with Capstone's compliance orchestration, KYC/KYB APIs, and risk-based approach for digital commerce and fintech customers.
• ComplyAdvantage: ComplyAdvantage provides AML, KYC, and transaction monitoring intelligence with APIs for banks and PSPs. It directly competes with Capstone's compliance orchestration and AML backbone for the same regulated financial institution buyers.
• Marqeta: Marqeta provides card issuing and payment infrastructure APIs with orchestration, routing, and developer tooling. It directly parallels Capstone's payment orchestration and API-first positioning for PSPs and fintech platforms, though Marqeta is card-centric and public.
• Spreedly: Spreedly provides payment orchestration and routing APIs for PSPs and platforms via a vault- and gateway-agnostic architecture. It closely mirrors Capstone's payment orchestration, developer portal, and global routing capabilities for similar enterprise buyers.
• Thought Machine: Thought Machine builds cloud-native core banking technology with API-first architecture. It competes with Capstone's UNI-RAIL middleware approach for legacy core modernization, though Thought Machine typically replaces rather than wraps legacy cores.
• Primer: Primer offers a payment orchestration platform with routing, reconciliation, and no-code workflows for merchants and PSPs. It directly competes with Capstone's payment orchestration module in the same enterprise customer segment with similar developer-first positioning.

Broad incumbents

• Stripe: Stripe is a global payments platform with broad payment orchestration, routing, and developer-first APIs. It overlaps with Capstone's payment orchestration, API-first developer portal, and enterprise field sales motion, though Stripe operates at vastly larger scale and is not focused on legacy core banking middleware.
• Adyen: Adyen is a global payments platform offering unified commerce, processing, and orchestration for enterprises. It competes with Capstone's payment orchestration offering for large financial institutions and PSPs, though Adyen operates at a much larger scale and is a public incumbent.
