Ozlo, a Palo Alto-based artificial intelligence startup, says on its website that it is joining the Messenger team at Facebook. Ozlo says, "When we started Ozlo, we saw a tremendous explosion of on-the-go communication. We wanted to build a new way for people to connect with each other, gather information and discover services.

Our world-class team has built a knowledge graph containing over 2 billion entities and created amazing AI technology that uses this data to understand real-world nuances. Now, we're ready to take the next step in our journey with Messenger. By joining a team that shares our values and our vision, we will be able to continue to work on building experiences powered by artificial intelligence and machine learning. There's a lot more for us to explore ahead and we're excited to bring our technology to the Messenger community."
