As of 2026. To date, Lesterius has not published anything about AI. Not because we are not working with it, quite the opposite, but because we first wanted to understand where AI truly adds value, beyond the hype.

Does Lesterius do nothing with AI? Certainly not. However, the step from digitalization to AI is not a small leap. It is a field of tension in which we are also searching for the right approach. How do you ensure that technology remains a means, and not an end in itself? The common thread has nevertheless remained simple: we continue to solve our customers’ problems. What does change is the importance of analysis. Understanding what is really going on becomes more important than ever.

Our reality today is broad. On one hand, we guide customers who still take orders with pen and paper. On the other hand, we help customers feed their sales teams with AI-generated leads: who is the right prospect, who should you contact, what is their background, and where are the opportunities? The contrast could hardly be greater. Yet it is all part of the same daily practice.

Are we working with AI? Absolutely! For our developers, AI has become a standard tool. It makes them more productive and accelerates the development process, but at the same time requires more critical thinking. AI takes work off our hands, but not responsibility. As developers, we must continue learning how to use AI correctly and efficiently, and remain sharp about what we build.

But just as important is what AI makes possible for our customers: digitalization, next level. Today, we see applications emerging that significantly reduce manual work, often starting from existing data: automatically creating and sending quotes, automatically answering support questions, preparing sales conversations, calculating cost prices based on historical data, optimizing schedules, or handling claims based on contracts. This is not science fiction, but tangible applications that we are already working on today.

What changes is the approach. Where we used to develop together with the customer and evolve along the way, the effort now shifts to the beginning. We invest more time in analysis, in clarifying the question, and in understanding the context. The development itself often goes faster, but only because the thinking beforehand is more thorough.

This also means that topics such as infrastructure, security, architecture, and integrations become more important than ever. Documentation is no longer a side note, but a foundation. Where there used to be less room for it, it is now essential to maintain the necessary flexibility.

The conclusion is clear: today we can achieve more with the same budget, without significantly sacrificing flexibility. But it requires a different way of working. AI ushers in a new technological revolution, with fewer limitations than before. We welcome that.

But it does not change our mindset. The customer who is still at the beginning of their digitalization journey is just as important to us as the customer who is fully engaged with AI. In both cases, it comes down to the same thing: increasing productivity and solving problems.

AI is new. Our mission is not.
