A leading health care benefits provider needed to modernize 10,000+ COBOL and Synon mainframe screens to improve claims processing and customer service.
With Slingshot, the provider uncovered hidden business rules and dependencies, enabling faster, safer migrations. Automated test generation sped up QA while reducing manual errors.

RWE faced an operational risk: a number of aging, undocumented applications were running on outdated technology stacks.
Slingshot, paired with human oversight, helped RWE revive a 24-year-old app with no source code or documentation in two days.

Before you rethink how legacy code becomes modern software, here’s what enterprise teams want to understand first.
Traditional modernization tools jump straight from old code to new code, which introduces risk and breaks undocumented business logic. Slingshot inserts a specification layer between legacy and modern systems. It reads existing code, extracts the business logic and converts it into a clear, testable specification. That specification becomes the source of truth used to design and generate modern code with full traceability. This is what allows Slingshot to modernize faster without losing accuracy or control.
Slingshot analyzes legacy code to identify rules, dependencies and behaviors that are often undocumented or locked in the heads of SMEs. That logic is captured as a machine-readable, testable specification before any new code is generated. Because the specification drives the transformation, Slingshot ensures the modern system behaves exactly as the original—only cleaner, faster and easier to evolve. This reduces dependency on scarce legacy experts and lowers modernization risk.
Slingshot is designed for large, complex enterprise systems, including:
It is particularly effective where systems are business-critical, poorly documented and too risky to rewrite manually.
Slingshot generates modern code directly from the specification and design, not from guesswork or prompts. Because every line of output code traces back to a verified specification, Slingshot delivers up to 99 percent code-to-spec accuracy. This traceability makes modernization auditable, testable and suitable for regulated environments.
Rewrite and replatform strategies often fail because they rely on assumptions about how legacy systems work.
Slingshot reduces risk by:
This allows teams to modernize incrementally and confidently, rather than betting everything on a single cutover.
