Katuu is a location-based social connection platform designed to help people meet others who are in the same place at the same time. Rather than focusing on distant matches or online feeds, it shows users who is currently at nearby venues and open to connecting. People can browse places on a list or map, check who is there before entering, and create a location if it is not listed. When users enter a venue, a selfie taken in the moment confirms their presence, helping ensure profiles represent people who are actually there.

Users can learn a little about others, select an intention—open to interaction, professional networking, social conversation, or a closer connection—and send a discreet greeting. A conversation starts only if both people agree, and either person can end it at any time. Katuu says it does not keep a history of visited places, searches, or completed conversations. The service also offers venue-related coupons when available.
