We believe in a future where we will live and work hand in hand with intelligent machines. To this end, machines will need to learn to communicate like humans do.

At Tribe, we bring conversational A.I. to life by giving it a human face. Why? Because the most natural interface is a face.

Interacting face-to-face lets you gaze into each other’s eyes, smile or keep a straight face, and react to that naturally. We have created a technology that can spark the human element in any application, from A.I.-powered customer support bots over virtual store assistants to the next generation of in-game characters.
