The Hack Košice 2026 hackathon, which was also attended by a team from the Faculty of Information Technology at CTU (FIT CTU), once again proved that an enormous number of ideas, projects, and inspiring stories can emerge within a single weekend. The sixth edition of Hack Košice welcomed approximately 180 participants from across Europe and other parts of the world. Participants had exactly 24 hours to create a functional prototype, while workshops, mentoring, and an accompanying program were available alongside the development process itself. The FIT CTU team brought home two awards from Košice.
The team consisting of Dávid Kepič, Adrián Mikolaj, Róbert Hudák, and Tomáš Hutňan (MUNI) impressed the jury with their project TatraShare. In the project, the team focused on solving the everyday problem of shared finances. The inspiration came from a common situation in which one person pays a shared expense and then has to awkwardly collect money from the others afterward. TatraShare expands this concept into comprehensive shared finance management, allowing users to create groups, manage shared budgets, set savings goals, or simply split one-time expenses.
The application uses artificial intelligence for automatic receipt processing, item recognition, and fair expense distribution among group members. Users always have a clear overview of who owes what to whom and for which expense. Key innovations include the unique use and management of virtual accounts through PSD2 open banking and the TatraUltraFastPay™ system, which enables instant settlement of payments between group members — each user links their card once, and whenever a payment is made, the amount is automatically split among all participants in real time.
The project impressed not only with its technical implementation but also with its business potential. It functions as a natural acquisition tool for Tatra Banka — users invite each other, thereby expanding the bank’s ecosystem without the need for marketing campaigns.
TatraShare ultimately won the Tatra Banka challenge for the most innovative financial application and also received an award for the best use of the MongoDB database solution within the program of the international organization Major League Hacking.
“We really enjoyed the competition and had a genuinely positive experience. My team and I have participated several times already, and we have never been disappointed by the challenges, organization, workshops, mentoring, or the social side of the event,” said Dávid Kepič.
The event was held under the auspices of the organization Major League Hacking, with companies such as IBM, AT&T, JetBrains, and Tatra Banka participating by preparing specific technological challenges for the contestants.
