Proven enterprise outcomes
Learn how leading organizations use Slingshot to modernize existing code and ship new software.
The Impact
faster migration
cost reduction
The Problem
A leading healthcare benefits provider needed to modernize 10,000+ COBOL and Synon mainframe screens to improve claims processing and customer service. Traditional modernization methods had converted only ~10 percent of screens in three years, leaving high technical debt, slow workflows and frustrated teams
Our solution
With Slingshot, the provider uncovered hidden business rules and dependencies, enabling faster, safer migrations. Automated test generation sped up QA while reducing manual errors.

The problem
RWE Generation Ltd, one of Europe’s leading energy producers, faced a growing operational risk: a number of aging, undocumented applications were running on outdated technology stacks. These systems were essential to operating power plants, but impossible to update, scale or understand without extensive cost, risk, effort and downtime.
Our solution
Slingshot, paired with human oversight, helped RWE revive a 24-year-old app with no source code or documentation in two days, turning a critical legacy asset into a modern, maintainable foundation.

Slingshot FAQs
What leaders want to understand before committing Slingshot to the enterprise.
What is Sapient Slingshot?
Slingshot is an AI platform that automates and accelerates the entire software development lifecycle. It breaks down legacy systems, preserves critical business logic and generates accurate, production-ready code — while also supporting the build and launch of new software. Slingshot replaces fragmented tools and manual handoffs with a single, continuous system for modernizing and delivering software at enterprise scale.
How does Slingshot modernize legacy systems without increasing risk?
Slingshot reads existing code to extract rules, dependencies and specifications before anything is rebuilt. That logic is carried forward through code generation, testing and deployment so modernized systems behave exactly as intended. This approach reduces guesswork, limits rework and avoids the common failures of rewrite-from-scratch modernization.
How is Slingshot different from AI coding tools or copilots?
AI coding tools assist individual developers. Slingshot modernizes and delivers software at the system level. Slingshot carries enterprise context across discovery, design, build, test and deployment. It is built for large, tightly coupled systems where accuracy, traceability and governance matter — not just faster code completion.
Can Slingshot be used to build new software as well as modernize legacy code?
Yes. Slingshot supports both legacy modernization and net-new software development on the same platform. Teams can modernize existing systems while simultaneously building and launching new applications, without waiting for long transformation programs to finish. This allows enterprises to keep shipping while legacy systems catch up.
What outcomes can enterprises expect from using Slingshot?
Enterprises use Slingshot to reduce modernization timelines, cut manual effort and improve delivery reliability across the SDLC. Common outcomes include 40% higher productivity, up to 50% savings in modernization costs and 99% code-to-spec accuracy. Modernize 10 years of legacy code in just four years.
