what this hub covers
This hub covers Seoul — Gangnam, Seongsu, Mapo, Yeouido and Jongno — with SNU, Yonsei, Korea University, the Seoul Startup Hub and the Yeouido fintech lab as anchors. Most of the calendar is here.

8 cities are deliberately folded into no hub at all — an event in Ulsan, Suwon, Sejong, Jeju, Cheongju, Jeonju, Changwon or Pohang keeps its own city name and shows under all browse events.
