Modernize core banking without breaking it.

Hypercubic moves banks from COBOL to cloud in quarters — with line-level correctness proofs, audit-ready documentation, and the expertise of your senior engineers captured before they retire.

Hypercubic Intervention

Challenge	Solution
Retiring mainframe workforce with irreplaceable knowledge Core banking platforms built over 30+ years on COBOL, CICS, and DB2 are maintained by engineers approaching retirement. Each departure erases undocumented understanding of transaction flows, business rules embedded in copybooks, and critical batch job dependencies that no onboarding program can replace.	HyperTwin HyperTwin preserves your senior mainframe engineers' expertise in queryable form. New team members ask it about COBOL programs, JCL jobs, and CICS transactions instead of waiting days for overloaded veterans.
Regulatory compliance without system transparency SOX audits, Basel III capital calculations, and AML transaction monitoring all require demonstrable understanding of how systems process and store data. When auditors ask how a specific regulatory rule is implemented, teams spend weeks tracing logic across thousands of COBOL paragraphs and JCL procedures.	HyperDocs HyperDocs generates audit-ready documentation for every COBOL program, copybook, and batch job in your regulatory processing chain. Compliance teams get complete data lineage and business rule documentation without diverting engineers from production.
Failed modernization attempts from undocumented business logic Core banking re-platform projects routinely stall or fail because critical business logic is buried in decades of COBOL code, nested copybooks, and undocumented CICS program linkages.

HyperLoop HyperLoop produces business logic extraction across your entire COBOL codebase, mapping every conditional path, copybook dependency, and cross-program call.

Escalating MIPS costs with no visibility into optimization targets Mainframe MIPS consumption grows year over year, but without clear understanding of which batch jobs, CICS transactions, and DB2 queries drive cost, optimization efforts are guesswork. Teams cannot reduce what they cannot map.	HyperDocs HyperDocs maps your complete mainframe workload topology (batch job chains, CICS transaction flows, DB2 access patterns, and IMS segment calls), so capacity planning teams get the visibility to identify and eliminate inefficiencies.

Retiring mainframe workforce with irreplaceable knowledge

Core banking platforms built over 30+ years on COBOL, CICS, and DB2 are maintained by engineers approaching retirement. Each departure erases undocumented understanding of transaction flows, business rules embedded in copybooks, and critical batch job dependencies that no onboarding program can replace.

HyperTwin

Regulatory compliance without system transparency

SOX audits, Basel III capital calculations, and AML transaction monitoring all require demonstrable understanding of how systems process and store data. When auditors ask how a specific regulatory rule is implemented, teams spend weeks tracing logic across thousands of COBOL paragraphs and JCL procedures.

HyperDocs

HyperDocs generates audit-ready documentation for every COBOL program, copybook, and batch job in your regulatory processing chain. Compliance teams get complete data lineage and business rule documentation without diverting engineers from production.

Failed modernization attempts from undocumented business logic

Core banking re-platform projects routinely stall or fail because critical business logic is buried in decades of COBOL code, nested copybooks, and undocumented CICS program linkages. Teams discover missing rules only after migration, causing production incidents and rollbacks.

Measurable Impact

40%

Reduction in audit preparation time

Compliance teams generate auditor-ready documentation for SOX, Basel III, and AML requirements in hours instead of weeks, freeing mainframe engineers to focus on production work rather than answering audit questions.

Faster mainframe developer onboarding

New engineers become productive on COBOL and JCL codebases faster, using HyperTwin instead of waiting for senior SME availability.

60%

Reduction in modernization discovery costs

Core banking re-platform initiatives eliminate months of manual reverse-engineering by starting with an automated inventory of business logic, data flows, and system dependencies across the entire COBOL estate.

Common Questions

How does Hypercubic handle sensitive financial data?

Your source code and data never leave your environment. Hypercubic deploys within your infrastructure, processes data under strict contractual terms, and we never use customer data to train models.

Can Hypercubic work with our existing mainframe without disruption?

Yes. Hypercubic operates as a read-only intelligence layer. We connect to your source code repositories and runtime logs without modifying your production systems. There is zero impact on mainframe performance or availability.

How long does it take to see results for a core banking application?

Most financial institutions see a complete knowledge inventory of a critical application within 4-6 weeks. This includes dependency maps, business rule catalogs, and risk assessments—delivered as queryable, living documentation.

Does this replace our modernization strategy?

No. Hypercubic accelerates your existing strategy by providing the understanding foundation that most modernization efforts skip. Whether you are rehosting, refactoring, or replacing, you need to understand what you have before you can safely change it.
