With over 50 teams, 40 mentors, and 30 real-world challenges, this year’s Cluj Hackathon, held from May 24–26 2025, pushed boundaries in agentic AI — and made space for some of the brightest young minds in Romania and beyond to shine. The three-day innovation marathon, hosted by Bosch Engineering Center Cluj, drew not only hackers and developers but also investors, accelerators, and founders curious about the next wave of AI-native startups.

Organized by Adrian Vlasiu, the hackathon aimed to harness the power of artificial intelligence to address real-world societal issues. Participants were encouraged to develop AI-driven solutions across various domains, including education, healthcare, and emergency response. The event’s mission was clear: to create impactful technologies that serve the community.

Now in its third edition, Cluj Hackathon has established itself as a consecrated name in the global hackathon scene, recently recognized by the Major League Hacking as one of the top 100 hackathons in the world.

“That kind of recognition validates the quality of our teams, our mentors, and the energy we’ve been building here in Cluj,” said Adrian Vlasiu, the event’s founder and organizer.

The winners? Three radically different teams united by one trait: they built useful, human-centered products with global potential.

First Prize: AI Interior Design Assistant That Understands Your Style

Filip Csibi, a computer science student at the Technical University of Cluj-Napoca, teamed up with Mark Renner, a theology high school student passionate about computer science and one of the youngest participants of the hackathon, to win first place with a product that turned heads.

Their AI-powered interior design app that helps users visualize room layouts and purchase suggested furniture in a few clicks. Using OpenAI APIs and DALL·E 3, the app generates personalized room visuals and learns user preferences over time. Ideal for people who move often or want quick, affordable design help, the app could soon evolve into a 3D and VR-based design platform.

Despite being just a duo, the team delivered a highly-polished prototype and impressed judges with both technical execution and vision. Filip said the experience reinforced the importance of teamwork — and they are already planning to expand the team for next year’s edition.

Second Prize: A Chatbot to Fix University Bureaucracy

Few things frustrate students more than getting information from university secretariats. Matei Botezat, Bogdan Buruian, Luca Balasoiu and Bogdan Biris, all four computer science students from Babeș-Bolyai University, created a smart fix: a university helper chatbot powered by Google Dialogflow and Cloud Functions.

Their idea? Free up secretaries’ time and reduce student stress by automating answers about scholarships, Erasmus programs, student IDs, and more. Mentorship from experts like Maria and Zoli (Fetch.ai) helped them refine the app’s business potential and prepare it for rollout.

The next step: test a prototype at their own university and explore expanding across campuses via European grants or university consortia. It’s a hyper-local solution with cross-border relevance — and a practical example of AI as administrative glue.

Third Prize: Angel AI — A Calm Voice in an Emergency

From travel panic to cultural misunderstandings, the Angel AI team tackled a universal pain point: what happens when travelers face danger in unfamiliar places? Their AI-powered assistant app aims to provide immediate, culturally aware support in high-stress situations — from medical emergencies to legal trouble or natural disasters.

Originally pitched as a dynamic travel planner, the idea pivoted mid-hackathon to focus on preventive alerts, real-time assistance, and actionable advice in moments of crisis. The team — Cristiana Constantin, Marius Manea and Bogdan Caraeane, all three students at  the University of Bucharest — received key mentorship on shaping their go-to-market strategy and decided to explore white-label partnerships with insurers, travel platforms, or even competitors.

With a rebrand in the works and small features being rolled out to collect traction and data, Angel AI is aiming to become a digital safety net for travelers worldwide.

Mentors: Cluj’s Secret Weapon

Mentors played a critical role in guiding teams toward clarity and viability. One of them, Mo Zidan, highlighted just how far the Cluj tech scene has come, not trying to replicate Silicon Valley, but growing with its own distinct identity.

He was also struck by the confidence and global mindset of young Romanian talent — like the 14-year-old who pitched fluently to a panel of international judges. For Moe, participating as a mentor was a way to “give back” and help build bridges between Cluj and other tech hubs in Eastern Europe and Asia.

“It’s not about copying Berlin or San Francisco. Cluj should link with other rising hubs — places like Prague, Budapest, Jakarta, Seoul. We have the mindset now. And the talent.”

One major evolution at this year’s event? Teams didn’t just use AI as a gimmick — they built AI agents that could act: book transport, send documents, or adapt in real time to changing user needs. Mo described this as “the biggest leap forward” he’s seen at any hackathon so far.

“This year’s AI agents weren’t just reactive chatbots,” said Mo Zidan, one of the lead mentors. “They were capable of taking action — booking taxis during emergencies or rerouting flights. That’s a massive shift.”

AI, Creativity, and the Future: A Bosch Perspective

As the host of the Cluj Hackathon 2025, Bosch Engineering Center Cluj provided not just the venue, but a fertile ground for forward-looking innovation. For Maria Barbatei, Group Leader of VR & AR Activities at Bosch, what stood out most was the breadth and relevance of the solutions.

“First of all, in this edition, the variety of solutions was extremely wide,” Maria noted. “The participants tackled problems from several industries, and especially the winners provided a solution which is relevant to all of us as it influences our daily lives and helps us to design our work environment at the office or at home as it fits us best.”

Beyond the creativity and boldness of the teams, Maria emphasized Bosch’s ongoing investment in AI-driven development and a data-first culture:

“I believe that the development of AI in the next five years will be fast-paced, and this is the reason why at Bosch we focus on data-driven development, and aim to foster a data-first culture while staying ahead with the AI advancements. We do this with the projects and activities in the data-development area as well as with building communities to expand these competencies in the organization with a rich mix of learning formats and collaborative activities.”

Bosch’s innovation programs don’t just support external events like the hackathon; they’re also fueling internal breakthroughs, with multiple invention reports being generated every year. It’s a model of how corporate R&D and grassroots innovation can work hand-in-hand — and how Cluj’s tech ecosystem is positioning itself for long-term, AI-powered growth.

What’s Next for Cluj Hackathon?

The 2025 edition marked a turning point — with agentic AI becoming not just a buzzword but a tool for building real products with real users. The energy was palpable. So was the ambition.

As the Cluj tech ecosystem continues to mature, the hackathon proves it’s not just a launchpad for code, but a catalyst for startups, mentorship, and international partnerships.

Organizer Adrian Vlasiu sees even bigger things on the horizon: an expansion across Romania and Europe, the launch of a Senior Hackathon for professionals aged 30+, and the formation of a European Hackathon League to foster a cross-border community of builders.

“We’re creating a platform where ideas meet capital, mentorship meets execution, and regional talent meets global relevance”, Adrian said.

One thing’s certain: the future of AI isn’t being built in Silicon Valley alone — it’s also coming from a theology high school student in Cluj, a chatbot for university offices, and a virtual guardian angel for tourists.
