Software Product Modernization

We help your software product drive business results long into the future.

It's never been easier or faster to modernize a legacy app. Our U.S.-based teams use AI to extract business rules, translate legacy code, and accelerate high-stakes rewrites that drive business results.

What’s holding you back?

Your tech stack is outdated.

Your software is stuck on aging infrastructure. It's hard to scale, costly to maintain, and limits what your team can do.

It costs too much to add new features.

New customers and end-users are making demands that your software can’t flex to meet. The fragile codebase stops you from seizing new opportunities.

You’ve got a poor user experience.

Your product comes with constant negative feedback. People don’t want to use your product, though it serves a valuable need.

We’ve Modernized It all

Here’s a sample of some of the legacy tech we’ve modernized into contemporary solutions.

C++
COBOL
Legacy hardware, like AS400s
Visual FoxPro
Powerbuilder
Xamarin
IT-managed server environments (to the cloud)
Outdated handheld devices
Desktop applications (to the cloud)
And more...

What Sets Us Apart

In 20+ years of helping clients like you, we’ve built a brand promise other firms don’t match: a great product and a great client experience at a great value.

Here is the set of choices we’ve made—that other firms won’t:

Full Product Team

Unlike specialized service providers that only offer design or development, we help you focus on the bigger picture. Atomic provides and coordinates the multidisciplinary skillsets you need to ship a great product.

Advanced Tools & Practices

Every team member uses AI to move faster and build smarter. We invest hundreds of thousands of dollars each year in tools, training, and knowledge management so our clients can benefit from the latest software development innovations.

100%  U.S.-based Talent

Atomic only hires in our four U.S. regions, and we don’t offshore your project team. We find the best credentialed and experienced professionals. We have industry-leading retention and tenure rates.

Co-located Collaboration

Our teams work side by side in the same regional offices. Easy collaboration accrues massive value and speed to your project compared to remote teams that suffer from low cohesion and strained communication.

That’s why our clients rank us as the highest-rated custom software consultancy on Earth— out of more than 200,000 firms on the review site Clutch.co.
