Let's Collaborate 1 / 6
★★★★★
"DNA works with us to deliver digital systems at scale so that we can serve our customers digitally. They are both reactive to requests and proactive with ideas and proposals."
★★★★★
"I appreciated the collaborative spirit and the effort to deliver a reliable solution within a reasonable budget. The step-by-step approach with a demo before deployment made all the difference."
★★★★★
"DNA Solutions has delivered online tools that have made the client's employees and customers' lives easier. For instance, the client can now handle cases in a maximum of two days instead of five."
★★★★★
"The quality of the people I worked with and the seriousness of the project management stood out. DNA built a backend and app for a highway toll system, and the human side of the company is truly remarkable."
★★★★★
"The real connection between sales and delivery is what sets them apart. Most IT companies have salespeople disconnected from the people actually building the solution. At DNA, that's simply not the case."
★★★★★
"We collaborated on an innovative recruiting app, and what stood out most was the supportive atmosphere and the strong autonomy given to every team member."

Let’s Talk01What does DNA Solutions do as an enterprise modernization partner?
DNA Solutions builds and modernizes the mission-critical platforms European enterprises run on: billing and charging engines, tolling and road-charging systems, and the legacy Oracle and SAP infrastructure underneath. Our work covers legacy modernization, enterprise system integration, cloud migration, and custom software development, with AI and automation added where they deliver measurable value. The results are concrete, like over €1M in annual savings we have delivered for clients.
02How much does an enterprise modernization project cost?
Costs vary significantly based on scope. At DNA Solutions, a targeted proof-of-concept typically takes 8 to 12 weeks, with pricing tailored to your specific use case. A full platform modernization depends on the complexity of the existing system, integration requirements, and transaction volume. Key cost factors include discovery and scoping, development, infrastructure, and ongoing maintenance. European enterprises should budget for both the initial implementation and 15-20% annual maintenance costs. Contact us for a detailed quote based on your situation.
03Can a live platform be modernized without disrupting operations?
Yes. Keeping the existing system running is a core requirement of our delivery approach:
- Phased delivery: we replace components step by step, with clear validation gates before each switchover
- Parallel running: the legacy system and the new platform run side by side until the new one is proven on real data
- Resilient architecture: event-driven design prevents data loss during traffic surges and migration windows
- Continuous monitoring: issues are detected and resolved before they have operational impact
- Documentation and training: your internal teams can operate and maintain the platform independently after handover
04Which industries does DNA Solutions serve?
DNA Solutions works with European enterprises in toll and road infrastructure (multi-country billing, road charging), telecom and media (charging engines, subscriber platforms), fleet management (telematics data, operational intelligence), and retail and distribution (customer data platforms, demand forecasting). These industries share the same constraints: high transaction volumes, strict regulatory requirements, and platforms that cannot afford downtime. Organizations processing large transaction volumes on aging systems see the fastest return from working with us.
05How long does it take to implement an AI solution?
It depends on the scope. A targeted proof-of-concept, validating an AI use case on your own data and systems, typically takes 8 to 12 weeks. A full platform modernization, such as replacing a legacy billing engine or rebuilding core infrastructure with AI and automation built in, usually runs 12 to 24 months. We deliver in phases with validation gates at each step, so your existing system keeps running and you see working results long before the final delivery.
