Cleo is a members-only personal matchmaking service designed to make dating feel more personal and less like using an app. It operates through iMessage and SMS, where its AI matchmaker gets to know members through conversation, learning about their preferences, values, and dating experiences. Rather than offering profiles to browse or a queue of matches to swipe through, Cleo makes introductions one person at a time when it identifies a potential fit, explaining how the connection relates to what a member has shared.

Cleo also helps coordinate dates, including finding a time and suggesting places, so members can move from introduction to plans in the same text thread. Membership is by application, and the Cleo team manually reviews every applicant to help maintain a small, serious community. The service is currently available in New York City and nearby areas, including Hudson and Bergen County, Westchester, and Nassau County. Members can log in with their phone number to update their profile and photos.
