AI startup CoreStory launches to solve legacy software challenges with AI code intelligence platform

Legacy code has long been the silent roadblock inside enterprises: brittle, poorly documented, and expensive to maintain. Today, CoreStory emerged from stealth with a promise to turn those aging systems into something valuable. The San Francisco-based startup is launching its AI-driven code intelligence platform, built to help companies modernize software faster and with more confidence.

“Across all industries, organizations are looking to digitally transform their infrastructure but are quickly finding out that they lack the historical knowledge or context,” said Mike Lambert, CoreStory COO. “CoreStory is removing these barriers with an AI-driven code intelligence platform. Within days, rather than months, we uncover the original business requirements hidden in the code and then provide architectural and code insights for modernization. CoreStory turns legacy code into a strategic asset so enterprises can understand it at every level.”

CoreStory Launches: From Legacy Code to Strategic Intelligence

For many companies, modernization projects mean untangling millions of lines of undocumented code. Developers are left guessing at how systems were originally built, slowing down digital transformation efforts. CoreStory’s pitch is that AI can step in where old documentation fails. Large language models comb through legacy systems, reconstructing business logic, system relationships, and developer intent. According to Gartner, 75% of engineers are expected to use AI code assistants, with 63% of organizations already experimenting with them.

“Even the most capable AI systems improve with a higher quality of input. By integrating with CoreStory, applications like Devin, Cognition’s autonomous AI software engineer, better understand complex legacy applications through CoreStory’s precise, natural language system representations,” said Brian Smitches, Head of Partner Deployed Engineering at Cognition. “As more organizations look to improve their maintenance and reliability efforts or a complete modernization of their technology stack, CoreStory’s integration into Devin unlocks legacy code, enabling our customers to guess less and build more.”

The platform can process 100,000 lines of code in minutes, producing structured intelligence models that expose the hidden architecture behind legacy applications. CoreStory says this enables four main use cases: accelerating app modernization, simplifying ongoing maintenance, creating a base for AI-generated code that avoids black box risks, and onboarding developers more quickly.

Traditionally, modernization efforts required armies of specialists combing through code line by line — projects that often stretched to 18 months or more. CoreStory CEO Anand Kulkarni argues his startup flips that timeline. “Our AI-based approach allows these companies to rethink the requirements in the code and applications, adding in more functionality and features. CoreStory lowers the barriers to entry and provides enterprises with radical savings,” he said.

By focusing on turning legacy code into actionable intelligence, CoreStory is positioning itself at the intersection of AI and enterprise modernization. For developers, project planners, and testers, it offers a way to shorten timelines and reduce failure rates, while giving enterprises a clearer path to modern infrastructure.
