CoreStory tackles one of enterprise IT’s costliest problems: understanding and modernizing the trillions of lines of legacy code that underpin critical systems such as banking, healthcare and defense. Its Agentic Code-to-Spec platform automatically reads, maps and documents millions of lines of code, turning opaque applications into detailed, living specifications that both developers and AI agents can navigate. By pioneering Specification-Driven Development, CoreStory grounds all software—including the surge of AI-generated code—in explicit, natural-language requirements, keeping business intent and technical execution aligned. Enterprises that deploy the product report up to a 50 percent reduction in human development time, while research conducted with Microsoft shows a 51 percent accuracy boost for AI engineering agents using CoreStory’s specs. The result is shorter modernization timelines, lower project risk and a measurable, ROI-positive initiative for large organizations. With fresh capital, the company plans to accelerate enterprise adoption and further develop its AI-powered development workflows. No additional revenue or user figures were disclosed in the article.
