Some of the wonderful clients who have trusted us


For Existing Rails Applications

We don't shy away from existing apps—with all their technical debt and legacy code. For over a decade, we’ve inherited Rails applications built by other development agencies, freelance developers, and former in-house developers. Whether your app is outdated or needs custom work, our team specializes in getting your project back on track.

Fewer Dev Team Management Responsibilities

You’ll work directly with our developers, but you won’t have the massive responsibility of managing them. The Project Manager will serve as a technical translator, scheduler, and prioritizer for both your team and ours, freeing up your time to focus on other responsibilities.

A Proven Process

Our experienced team of developers offers collaborative support during each phase of the development cycle, from discovery to deployment and maintenance. We can help with both backlogged internal development issues and taking over projects from freelancers and other agencies.

Access to a Wider Library of Tools

There are various third-party tools that can benefit your application, from code quality inspectors to cloud storage to organization tools. We’ll work together to set everything up, train your internal team on how to use them, and keep your project moving forward.

Long-Term Stability

We’ve heard this story a dozen times: “My freelancer decided to get a full-time job, and they were the only person who knew my application. Now I have this backlog looming, and I have no idea how I’m going to get these things done.” That’s the beauty of hiring a team where 2-3 developers have basic knowledge of your project. Even if one developer leaves, there won’t be a big lapse in progress while another team member takes over their work.

Manager of Digital Information Systems at Office of the General Convention

Planet Argon is consistently responsive and delivers their tasks on time. They contact me when aspects of the project need to be discussed and provide me with a detailed approach to their plans and actions.

I am impressed at their ability to take on our multiple, complicated existing apps and learn them quickly and well, and quite happy with the numerous improvements they have made for us. Also, their attention to maintenance and support tasks, in addition to development, has been great.

Web Applications Supervisor at Screaming Circuits

Planet Argon has been an incredible stabilizing force for our web platform. We needed a partner who could plug the holes in our web environment and provide the tools needed for smooth development, testing and deployment. Planet Argon has more than met that need. They are without a doubt the most professional and adept development team I have worked with.

Digital Marketing Director at West Dermatology

While their approach to customer serivce and client relations is great, what I actually found most impressive was their ability to help develop solutions in creative ways. None of the complex content issues were a problem, and the team was always open to new information/new requirements regardless of where we were in the process.
