​🗣 The event runs in English. Live captions will be shown for Korean-language remarks during the opening ceremony.

​🚀 Overview

​Transpose Platform is excited to bring our c0mpiled hackathon series to Seoul for the first time, co-hosted with ASAN Nanum Foundation, Korea Venture Capital Association (KVCA), Korea Venture Investment Corp. (KVIC) and the Korea International Trade Association (KITA).

​c0mpiled is a one-day, build-first hackathon: pick a topic from Y Combinator's Request for Startups, build on site, submit a 90-second demo, and get judged the way Silicon Valley judges early teams.

​Since 2025 the series has run in San Francisco, Tokyo, and Osaka, with YC alumni founders as judges and mentors at every edition.

​💡 Why Join?

• ​Build next to YC alumni founders. YC alumni founders fly in with Transpose partner James Tan to judge and mentor on site.

• ​Get judged by Silicon Valley criteria. Judges look at what you shipped in five hours, how fast you moved, and how you handled pressure. Not your deck.

• ​Win office hours with a YC partner. The first-place team receives a one-on-one office hours session with a Y Combinator partner, plus KRW 3,000,000.
