How it works

1
Open or join in five minutes. An event needs only a name. Joining needs a name and an email — no account.
2
Find a team. Teammate suggestions match roles and goals. Contacts open only when both people press ‘Like’.
3
Ship in a day. Build with AI, demo for two minutes, and keep a public record you can paste into LinkedIn.
Our mascot 노랑이 (Norangi) is a power plug — HACK:ON is where your first app gets switched on.

Open events

Titles are in Korean. Many organizers are glad to help in English — ask in the event's Q&A, or use your browser's translate.
