Serendi is a social discovery app by Serendicity Co., Ltd., designed to connect people through shared offline experiences. Rather than relying on profiles alone, it invites participants to meet in settings where interests and personalities can emerge naturally, including film screenings, exhibitions, tastings, and other events. Programs include group introductions and rotation-style gatherings, as well as one-to-one matching experiences, with examples offered in areas such as Seongsu, Euljiro, and Yeoksam.

Participants choose a date and program, apply, and receive information by text message before meeting at the designated venue. They can enjoy the activity, talk about their interests and values, and then express interest in someone they would like to meet again. Serendi aims to make conversation easier by giving people a shared experience to begin with. For connections that do not happen at an event, the app also introduces one new person each day from among people who have joined through Serendi. The app is available on Google Play and the App Store.
