NINIGU
Read full descriptionHide full description
Not a stranger, but someone your friend says, "I think you two would really hit it off." A first meeting that begins with excitement rather than awkwardness. That's the kind of introduction NINIGU believes in. NINIGU brings the familiar tradition of being introduced through friends into the digital world. Just because someone catches your eye doesn't mean you're instantly connected. First, a friend who knows both of you reviews the introduction request. If they believe it's a good match, the request is passed along to the other person. And only when the other person chooses to accept does the conversation begin. Instead of connections that come and go in an instant, NINIGU is about introductions that are a little more thoughtful and a little more genuine. The comfort of hearing a friend's recommendation. The excitement of thinking, "Maybe this is someone I'd actually like to get to know." NINIGU is here to support the relationships that begin that way. [Browse] Discover new connections through friends of friends. Use filters such as gender, age, and location to explore people who match your preferences. [Friend's Introduction Circle] Join your friends' Introduction Circles and receive introductions from people who know you best. Once accepted into a friend's Introduction Circle, you'll be able to view more detailed profiles and photos. [Matches] Found someone you'd like to know better? Send a match request. Your request isn't sent directly to them. Instead, a mutual friend who knows both of you reviews the request and decides whether to approve the introduction. If the introduction is approved, the other person receives your request along with a note from that mutual friend. Only when they choose to accept does a new conversation begin. [Profile] Share your photos, interests, values, and personality. The more authentically you express yourself, the better your friends can introduce you to someone who truly fits. Sometimes, the people who know us best make the most meaningful introductions. NINIGU. A new dating experience inspired by the warmth of real-life introductions. Start something more meaningfulβwith trust, excitement, and a recommendation from someone who knows you best.
