# CoreStory

> CoreStory is a San Francisco-area AI startup building a persistent 'spec layer' for software. Its Code-to-Spec platform ingests legacy codebases - the COBOL and decades-old systems running banks, airlines, Social Security and Medicare - and turns millions of lines of undocumented code into living, queryable specifications that both humans and AI coding agents can read. Founded by Anand Kulkarni, the company raised a $32M Series A in October 2025 to make the world's aging software understandable again, reporting up to 50% reductions in development time and a Microsoft-validated 51% accuracy boost for AI agents fed its specs.

- **Founded:** 2024
- **Headquarters:** Berkeley, California, United States
- **Founders:** Anand Kulkarni (Founder & CEO), Charath Ram Ranganathan (Co-Founder)
- **Team size:** ~32 employees
- **Products:** Code-to-Spec, Core Platform (Persistent Intelligence Model), MCP / API Integrations, AI-Assisted Spec Generation & Playbooks
- **Notable:** Raised $32M Series A in October 2025 led by Tribeca Venture Partners, NEA and SineWave Ventures., Microsoft joint research: +51% accuracy for AI software-engineering agents using CoreStory specs., Reported up to 50% reduction in human development time for enterprise modernization.

## Products & services

- **Code-to-Spec** — AI platform that ingests legacy codebases and automatically generates living specifications: natural-language feature overviews, architectural summaries, annotated code-snippet explainers with visualizations, dependency maps, and modernization recommendations.
- **Core Platform (Persistent Intelligence Model)** — Ingests source code and builds a persistent intelligence model that serves accurate system context on demand to architects, product managers, developers, and AI coding agents.
- **MCP / API Integrations** — Lets AI agents such as Claude Code, GitHub Copilot, Cursor, Devin and Droid query CoreStory's code intelligence directly, like an atlas for the codebase.
- **AI-Assisted Spec Generation & Playbooks** — Guided spec creation for common workflows plus ready-to-use playbooks with pre-built integrations for coding agents.

## Achievements

- Raised $32M Series A in October 2025 led by Tribeca Venture Partners, NEA and SineWave Ventures.
- Microsoft joint research: +51% accuracy for AI software-engineering agents using CoreStory specs.
- Reported up to 50% reduction in human development time for enterprise modernization.
- Reported ~70% reduction in AI token spend via better context, and +50% speed to working solutions.
