This repository is a curated list of companies that extensively use Common Lisp and Scheme in their technology stacks. It serves as a resource for developers seeking Lisp-friendly employers and for companies looking to showcase their use of these languages. The list aims to highlight the practical, widespread adoption of Lisp in various industries.

How It Works

The repository is organized geographically, listing companies by continent and country. Each entry includes a brief description of the company's work and how they utilize Lisp, often citing specific projects, products, or internal systems. This crowdsourced approach relies on community contributions to maintain an up-to-date and comprehensive overview of Lisp's commercial applications.

Quick Start & Requirements

This is a curated list, not a software project. No installation or execution is required. The primary resource is the README file itself, which contains links to company websites, job postings, and further Lisp resources.

Highlighted Details

• Features companies across North America, Europe, Asia, Africa, and more.
• Includes a wide range of industries, from aerospace (Boeing) and finance (Eaton Vance) to AI (Grammarly) and quantum computing (Rigetti).
• Highlights specific Lisp implementations used, such as Allegro CL, SBCL, LispWorks, and Scheme variants.
• Provides evidence of Lisp's longevity and continued relevance in production environments, with some companies using it for decades.

Maintenance & Community

The list is maintained through community contributions, with guidelines provided for adding new entries. It references external resources like LinkedIn groups and Lisp-lang.org for broader community engagement.

Licensing & Compatibility

Limitations & Caveats

The list's accuracy and completeness depend entirely on community contributions and may not reflect the most current technology stacks of all listed companies. Some entries are dated, and the "Virtual or Unsure of Location" section is broad.
