SNU × Croche AI App Hackathon: Real AI Apps from 20 Teams in 2 Days
Our Journey is a short, photo-led series about the places the H1R.ai team has been.
On October 17, 2026, the final round of the SNU × Croche AI App Hackathon, co-hosted by the Seoul National University Startup Center and H1R.ai, took place on SNU's Gwanak campus. 420 students from 105 schools applied, and 20 teams made it to the final.
The 20 finalist teams built working AI apps with Croche in just 2 days: games where you talk with characters, personalized learning helpers, everyday productivity apps. Each app ran 2.9 AI agents on average, and up to 7. The participants showed for themselves that you can build apps where several agents work together without writing your own AI backend.
After opening remarks by Prof. Nojun Kwak, each team gave a 5-minute presentation with Q&A, followed by table demos. Rankings combined judges' scores and peer votes from the teams, half and half, and team 손민수랩 took first place. Total prize money was 10 million won.
Four judges scored the final:
- Daesik Kim — former Senior EVP at Naver Webtoon, former CEO of Bidadoo
- Juntae Lee — Principal Researcher, Qualcomm
- Kyuhong Shim — Professor of Software, Sungkyunkwan University
- Simyung Chang — CEO of H1R.ai, former Principal Researcher at Qualcomm
Many teams are still refining their apps with Croche. For us, it was the first day we saw up close how Croche works in real developers' hands.
