Not a stranger โ€” someone your friend thinks you'd really get along with. NINIGU brings the familiar tradition of being introduced through friends into an app built around the people you already know. [Friends] Add the friends you know in real life. Everything on NINIGU starts from these real connections โ€” there is no browsing of strangers. [Introductions by a trusted friend] Friends can create an Introduction Circle of friends they know well and vouch for. When you'd like to be introduced to someone in a friend's circle, your request goes to that friend first โ€” not to the other person. Your friend decides whether the introduction makes sense, adds a short note, and only then passes it along. A conversation starts only if the other person also says yes. [Be the matchmaker] You don't have to be looking for anyone yourself. Many people use NINIGU simply to introduce two friends who might get along. [Plaza] Join hobby boards, share posts and photos, comment, and plan meetups with people who share your interests. Save meetup posts to your calendar. [Meetings] Friends can arrange small group meetups together and chat in a shared room before meeting. [Profile] Share your interests, values, and a favorite song, so friends can introduce you thoughtfully. [Safety] โ€ข Introductions always go through a mutual friend and require both people to agree โ€ข Report and block from any profile, chat, post, or comment โ€ข Users must be 19 or older Sometimes the people who know us best make the most meaningful introductions. NINIGU โ€” introductions from people you trust.
