The rising number of luxury apartment buildings is putting property managers under increasing pressure to entice new tenants — and to convince current ones to stay when their lease is up. When round-the-clock doormen, a state-of-the-art fitness center and a residential lounge are seen as standard, how can property managers set their building apart? Jude Chiy founded resident engagement platform Flamingo to offer a solution. Not only can residents use it to do useful things like pay rent and make maintenance requests, Flamingo also allows property managers to easily offer concierge-style services like dog-walking, cleaning and personal training sessions.
