Our journey

Every idea has
a beginning.

From a first conversation between colleagues to our own company: discover the milestones in our story.

What connects us

A curiosity for code and markets.

Marco is interested in stocks, neural networks and artificial intelligence. Dennis explores trading and has been programming since his first ‘Hello World’ in 2004.

We share a question: how can complex data become understandable insights? It inspires us to turn our own ideas into software.

Spring · Our first meeting

Colleagues. And soon much more.

We meet as systems integrators at the same company. Through computer hardware, chart patterns and conversations about software, we quickly discover shared interests.

During the pandemic, we take the time to explore ideas, develop technical concepts and turn our first shared approaches into code.

Mid-year · The spark

The idea for StockNav takes shape.

The sheer volume of market data raises a concrete question: how can we extract useful information for analysis from this stream of data?

With StockNav, we begin to pursue this idea. Our focus is on neural networks, financial market data and the development of our own analytical methods.

Late in the year · Putting it to the test

Develop. Test. Rethink.

The first alpha versions show us where more work is needed. We revise algorithms, adjust model parameters and initially evaluate results using simple Excel analyses.

Through experiments, mistakes and corrections, a structured development process gradually takes shape. This experience influences how we approach technical challenges.

December · A company of our own

Our idea becomes NoLimitsCoding.

By signing the articles of association, we establish NoLimitsCoding GmbH. Our shared development work becomes a company of our own.

Alongside coding, business planning, marketing and preparing for conversations with investors become part of our daily work.

The next stage of development

Bringing the pieces together.

The core algorithms form the foundation for StockNav's next phase. We work on bringing the individual components together and further developing the user interface.

At the same time, we prepare the next business steps and present our work to potential investors.

September · A springboard

Fresh ideas through HubGrade.

We are accepted into DigitalHub's HubGrade accelerator programme. Conversations with specialists, mentors and other start-ups open up new perspectives on our work.

We use the feedback to refine our direction, review strategies and move StockNav's development forward.

October · Our IT service launches

Turning experience into support.

As systems integrators at K&M Computer, we have seen the difference reliable IT makes in everyday work. We listen, get to the root of problems and enjoy helping others – because technology excites us and good solutions make people's work easier.

In October 2026, we turn this experience into another NoLimitsCoding offering: our IT service launches initially for businesses and start-ups. We help with workstations, networks and technical questions in day-to-day operations – with personal, clear support and a shared commitment to finding a solution.

In development: The minimum viable product (MVP) is scheduled to launch in December 2026.
