Public administration doesn't need another boring presentation; it needs courage and a bit of showmanship. It was precisely with this idea that on August 25 and 26, 2026, we organized the Innovation Circus, a conference that chose a theater stage instead of a boring podium. The main show took place live on August 26 at the Ján Palárik Theatre in Trnava, where the auditorium for one day […]

It's Wednesday, three o'clock in the afternoon, and it's 33 degrees outside. There are three people in the office and one air conditioner that has given up. An email arrives from a client: they need a confirmation that only Janka can issue. Janka is currently on vacation and, understandably, does not feel like answering her phone.

This is the daily reality for most Slovak municipalities. In our experience, the average [...]

Let's admit one thing. Almost everyone uses artificial intelligence today. Some people write texts with it, some create presentations, some have Excel tables generated for them. AI has become a universal assistant: you open it, ask a question, get an answer, and continue.

At Opium.systems, we love innovation, and sometimes we even „cook“ it up. One of our most unique activities, which we recently implemented at the Slovak Savings Bank's business conference, BIKOSS 2025, is the cooking show „How to Cook a Digital Workflow.“ Why did we have a cooking show, anyway?

Do you know that feeling when everything is going smoothly? Orders arrive on time, customers are satisfied, deliveries run without problems, and the entire process works like a well-oiled machine.
