How do these top companies compare in terms of pricing and project size?

While pricing varies widely, most firms on this list cater to mid-to-large scale transformation projects. What sets them apart isn’t cost but the strategic value they deliver. Especially so in complex modernization efforts.

Which top companies use AI and automation in application modernization?

Several leaders on this list, like Radixweb, embed AI and automation at the core. With that, we are able to drive faster code refactoring, smart testing, and predictive maintenance. This enables meaningful transformation, not just lift-and-shift upgrades.

Are there any US-based or global companies in this list?

Yes, the list includes both US-based firms and global players with delivery hubs across regions. This blend ensures you find partners with a strong local presence or global delivery muscle whatever your model demands.

Which app modernization companies are best for AI-driven transformation?

If you are looking for companies for AI-driven transformation, you need a partner that treats AI as an enabler, not a bolt-on. At Radixweb, for example, we re-architect legacy apps using AI/ML for decision intelligence, process automation, and user personalization.

Can I modernize just one part of my application instead of the entire system?

Yes. This is known as incremental modernization. In fact, most organizations we work with start by modernizing high-impact modules first. The lower-priority parts of the system are left for later. With this practical approach, you can reduce risk and validate improvements before scaling.

Will I lose existing data during the modernization process?

Data loss is one key challenge that can arise due to mistakes in the legacy app modernization process. As experienced app modernization partners, we use structured migration techniques, backups, and testing to ensure seamless and secure data transfer. That’s how we keep your data safe and secure.

Do I need to hire new talent internally post-modernization?

Not necessarily. After project completion, we share proper documentation and even hold knowledge transfer sessions. With that, your existing team can often manage the new environment. However, we do recommend upskilling the team in areas like DevOps, cloud management, or microservices.
