What they said about past events
Previous Hack Kosice hackathons hosted many hackers, sponsors, partners and friends. Here is what some of them said about the event.
Hack Kosice 2023 was my first-ever hackathon experience, and it was amazing! In just 24 hours, I learned so much and had a lot of fun. The atmosphere at the event was fantastic, and I was delighted with the presence of traditional Slovak dishes like “pirohy” and “halušky”. I would love to come back next year and participate again. Thanks so much for organizing such a great event!

HK23 AttendeeHack Kosice made me experience first-hand the power of collaboration in a diverse, aligned team. I would have never even thought of developing a multi-purpose app in one day by myself! That kind of self-validation pushes young scientists to take the initiative and found startups.

HK23 AttendeeOur experience during Hack Kosice 2022 was beyond our expectations. The mentors did awesome job polishing our ideas, and each challenge was interesting in different ways. The supply of great food and coffee was the cherry on top. We enjoyed “hacking” in Kunsthalle, and look forward to the next hackathon.

Visma challenge winner at HK22I have attended more than 50 hackathons worldwide and Hack Kosice is among the best events I have been to. The event felt really well put together and the production quality was absolutely top notch.

Major League HackingHack Košice 2022 was an amazing event! We encountered a lot of talented engineers, and an amazing organizational team (and the quality was so great we still cannot believe it mostly consisted of students!). We’d witnessed and had been a part of some high-quality networking, great challenges, and a really, really great atmosphere.
