Airbnb was born in 2007 when two hosts welcomed three guests to their San Francisco home, and has since grown to over 5 million hosts who have welcomed over 2 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. The Community You Will Join: Everyone at Airbnb thinks about trust, but our team obsesses over it daily. The Trust team is responsible for protecting our community and platform from fraud and safety issues while also ensuring our hosts, guests, homes, and experiences meet our high standards. The Adaptive Risk Investigation (ARI) team creates foundational tools that empower Trust Operations to integrate and scale human intelligence in Trust Defense. The team works closely with the Trust defense teams and the Operations team to tackle the changing landscape of fraud and safety issues, and build platform features to enable Trust products and Operations teams to quickly build investigations queues and take enforcement actions.
