About us

TIS Grupa is a global IT company with 35 years of experience developing complex fintech solutions. We have been a reliable IBM, Microsoft, and Oracle partner from the beginning and have since expanded our tech stack portfolio to include all relevant industry standards.

The Croatian National Clearing System (NKS) is one of our most remarkable achievements. NKS was developed in collaboration with Fina in Croatia thanks to our renowned expertise in SEPA regulation. Furthermore, we have introduced the euro in two countries. With offices in Slovenia and the UK, TIS Grupa serves the financial sector throughout Europe and is pleased to collaborate with six of the ten largest British banks.

Thanks to our experienced business analysts and project managers, TIS Grupa is recognized as one of the leading consulting firms in the regional market, especially in introducing innovative banking services.

Although we started experimenting with artificial intelligence in the 90’s, we have intensified our focus on AI solutions. Computer vision, machine learning, and LLM’s are the favorite tools in our in-house AI squad.
