Airbnb was born in 2007 when two Hosts welcomed three guests to their San Francisco home, and has since grown to over 4 million Hosts who have welcomed more than 1 billion guest arrivals in almost every country across the globe. Every day, Hosts offer unique stays and experiences that make it possible for guests to connect with communities in a more authentic way.

Search is pivotal to the Airbnb marketplace, and Understanding Who are our Guests and What they want is at the heart of providing thoughtful personalization and a high quality user experience. The core of the Airbnb platform is hospitality and we aim to become the ultimate host for our users, at every detail. To achieve such a goal, the Data Science team mines various collections of behavioral data to design and build machine learning models to understand our user experience and to optimize the useful presentation of our product. This derived understanding of our users informs product improvements that make the steps from search to booking easy and fast for guests.
