Is it also your biggest liability?
NK‑CODEx autonomously automates complex stages of the critical software development lifecycle using trustworthy AI. It translates legacy code and verifies that the output behaves exactly like the original. It generates unit test suites with 100% coverage from source code alone. Autonomous AI agents deployable on‑premises or in the cloud that produce verifiable code, regardless of project size,not assistants that simply support your developers.
The software that underpins your business is becoming your greatest risk.
The critical applications you have maintained for decades are large, complex, robust and reliable. Yet their foundations are beginning to fail. They rely on programming languages the market is abandoning, development lifecycles that depend heavily on individual
expertise, knowledge that is disappearing, and suppliers you cannot easily replace. At the same time, current approaches demand excessive time and resources.
Technology dependence
Your critical software relies on obsolete languages (COBOL, legacy Java and older C/C++). Every year, maintenance costs increase while your ability to evolve the software decreases.
Skills
shortage
There are fewer and fewer engineers with deep expertise in these technologies. Those who remain are expensive, difficult to retain and approaching retirement.
Rising maintenance costs
Keeping legacy systems alive consumes increasing amounts of budget in licences, specialist staff and infrastructure—without creating any new business value.
Cybersecurity and compliance risks
Legacy software does not receive security updates at the pace of modern platforms. Every unpatched vulnerability increases operational, regulatory and reputational risk.
Autonomous AI agents.
- Deliver solutions in less than 10% of the time and cost of traditional approaches.
- No practical code-size limitations.
- Deployable on‑premises or in cloud.
NK‑CODEx is a trustworthy AI platform that autonomously modernises legacy code and performs critical software testing, backed by the judgement of a team with 25 years' experience developing software for environments where failure is not an option.
True autonomy
The agents complete the work from start to finish. They do not assist developers, they do the work. Human involvement focuses on supervision and validation, not production.
Verifiable reliability
The result is not code that ‘will probably work’. It is tested, verified and documented code with measurable technical guarantees, written in a form your team can understand and maintain.
Embedded expertise
Behind the platform is a team with 25 years of experience in industrial critical software. That expertise is embedded into the way the agents operate.
Flexible deployment and cybersecurity
We deploy NK‑CODEx and the AI models that power it in the environment of your choice: our secure cloud, your private cloud or your own hardware, even in air-gapped environments.
How NK-CODEx works
Two capabilities.
One platform.
Your code under control.
NK‑CODEx addresses two of the biggest challenges in enterprise software. It combines a proprietary platform with an expert team, meaning you receive not only a tool but also the support of specialists with decades of experience modernising critical software.
- Capability 1
- Capability 2
Legacy Code Modernisation
The challenge
Legacy code migration projects often take years, involve significant costs and carry considerable uncertainty. Traditional consultancies rely on manual processes supported by AI copilots, while generic AI tools lack the domain knowledge required for critical software.
What NK‑CODEx does
NK‑CODEx autonomously and verifiably translates legacy code into modern programming languages. It enables migration projects to be completed in timeframes and at costs that were previously unthinkable, making even highly complex migrations feasible.
Languages currently supported
From COBOL to C or Modern Java. From Java Struts to Spring Boot. Other language pairs are evaluated on request.
Typical results
A conventional COBOL to Java migration assisted by AI copilots typically requires between one and two years and costs between €2 million and €4 million per million lines of code. NK‑CODEx translates and verifies one million lines of COBOL into modern Java in approximately two weeks.
Automated, Trustworthy Unit Testing
The challenge
For unit testing to be effective, it often requires as much effort and time as software development itself. As a result, many organisations reduce or skip this phase, increasing long-term maintenance costs and technical risk.
What NK‑CODEx does
NK‑CODEx automatically generates trustworthy unit tests from existing or newly developed source code. It is the first solution capable of introducing autonomous unit testing at scale without constant human intervention, regardless of codebase size.
Languages currently supported
ava, COBOL and C/C++. Other languages available on request.
The results we obtain
100% unit test coverage with approximately 10% of today’s effort and cost.
Implementation in Four Steps
Pilot Project
We begin with non-critical code so that you can evaluate the results without risk. This includes code review and obfuscation where required, a basic cybersecurity assessment, and a pilot based on your own software.
Technical Review and Project Definition
If the pilot is successful, we carry out a detailed assessment covering code characteristics, deployment model, cybersecurity, business continuity and data governance. Commercial terms are finalised only once all technical and operational aspects are clear.
Execution
If we identify scenarios that the platform cannot yet process, we develop and integrate the required capability at our own expense. You remain in control throughout the entire process.
Deployment and Comparative Testing
We support you during implementation and comparative testing, applying iterative improvements until the outcome is fully validated. The legacy system is replaced only once the new solution has been verified.
Industries where NK-CODEx has a clear application
Any organization that develops and maintains its own mission-critical software can benefit from NK-CODEx. These are the industries where the challenge is most acute.
Banking and Financial Services
Core banking systems written in COBOL and running on mainframes. Decades of accumulated business logic that financial institutions need to modernize in order to reduce dependency on legacy technologies, contain operational costs, and enable the evolution of digital products on a modern infrastructure.
Industry and Manufacturing
Embedded C/C++ software for control systems, industrial automation, and specialized machinery. Mission-critical code that must be migrated or thoroughly tested whenever platforms are upgraded, hardware components are replaced, or new functionality is introduced.
Insurance and Financial Services
Legacy Java platforms and inherited actuarial management systems that need to be modernized to integrate with today’s digital ecosystems without losing the business logic that has been validated and refined over decades.
Public Sector and Essential Services
Administrative management systems, digital public service platforms, and mission-critical infrastructure systems that rely on obsolete technologies and need to be modernized while meeting stringent continuity, reliability, and security requirements.

FAQs
Frequently asked questions
How is NK-CODEx different from traditional modernization consulting firms?
Traditional consulting firms execute modernization projects using human teams assisted by AI copilots. NK-CODEx performs the work through autonomous agents that generate verifiable code. The result is significantly shorter delivery times, more predictable costs, and outcomes backed by concrete technical guarantees.
How is NK-CODEx different from AI coding tools like GitHub Copilot?
Tools such as GitHub Copilot assist developers in their day-to-day work. NK-CODEx does not assist your developers, it autonomously executes complete modernization and testing projects. It belongs to a fundamentally different product category.
Do we need developers with expertise in the source language to use NK-CODEx?
No. That is one of NK-CODEx’s key advantages. It enables organizations to modernize legacy systems even if their teams no longer have in-depth knowledge of the original programming language. The required expertise is embedded in the platform and supported by the Innkia team.
What happens if the modernized code contains errors?
Our methodology includes iterative validation and correction cycles, comparative testing against the original system, and an explicit warranty period. The legacy system is only replaced once the modernized solution has been fully validated.
How do you ensure code confidentiality and security?
A non-disclosure agreement (NDA) is signed before any evaluation begins. Source code is handled through secure review processes and obfuscation when appropriate. Cybersecurity audits and data governance are standard components of our methodology, and Innkia’s infrastructure can be subjected to customer-led penetration testing if required.
Which programming languages and versions do you currently support?
For modernization, we currently support COBOL to modern C# or Java, and Java Struts to Spring Boot. For automated unit testing, we support Java, COBOL, and C/C++. Additional language pairs can be incorporated on demand, depending on the project’s requirements.
How much does an NK-CODEx project cost?
Each project is priced according to its scope, the programming languages involved, and the chosen deployment model (SaaS, private cloud, or on-premises). Pricing is defined after the pilot phase, once we have concrete insights into your codebase. For indicative pricing ranges, the best starting point is an initial conversation with our team.
What is the first step to start working with NK-CODEx?
It begins with a technical discussion between your team and ours. If NK-CODEx is a good fit, we propose a pilot project using non-critical code so you can evaluate the results without risk before making any commitment.
