# Planet Argon

> Planet Argon is a software consultancy specializing in Ruby on Rails. We help small teams with existing applications improve maintainability, performance, and team workflows — and increasingly help teams navigate the shift to AI-assisted and agentic development. Our core philosophy is the Second Act: most existing Rails applications deserve to be understood and evolved, not rewritten. Our services include audits, upgrades, staff augmentation, AI safety and enablement work, and design support. We also contribute educational content and tools to support the long-term health of the Rails community.

- [The Second Act](https://www.planetargon.com/second-act): We help teams understand their applications, make clear modernization bets, and extend the life of software that's already proven itself. Sometimes that means upgrades. Sometimes refactoring. Sometimes new capabilities nobody expected. It rarely means starting over.

Covers maintaining legacy software, open source sustainability, and Ruby on Rails. Includes recordings and booking information for events and shows.
