Airbnb features a review system in which guests and hosts can rate each other after a stay. Hosts and guests are unable to see reviews until both have submitted a review or until the window to review has closed, a system which aims to improve accuracy and objectivity by removing fears that users will receive a negative review in retaliation if they write one. However, the truthfulness and impartiality of reviews may be adversely affected by concerns of future stays because prospective hosts may refuse to host a user who generally leaves negative reviews. In addition, the company's policy requires users to forego anonymity, which may also detract from users' willingness to leave negative reviews. These factors may damage the objectivity of the review system.

In November 2012, Airbnb opened an office in Sydney, Australia, its 11th office location, and announced plans to launch the service in Thailand and Indonesia. At that time, Australian consumers accounted for 10% of the Airbnb user base, and in December that same year, Airbnb announced its strategy to move more aggressively into the Asian market with the launch of an office in Singapore.
In January 2017, Brian Chesky, CEO of Airbnb, posted on Twitter that the company will give free housing to refugees and any others not allowed into the United States as a result of Donald Trump’s Executive Order 13769, which temporarily banned refugees from the United States. Airbnb also led a $13 million investment in restaurant reservation-booking app, Resy, along with serial entrepreneurs Gary Vaynerchuk, Ben Leventhal and Mike Montero.
One year later, there were 15 people working from Chesky and Gebbia's loft apartment on Rausch Street in San Francisco. To make room for employees, Brian Chesky gave up his bedroom and lived at lodging booked via the Airbnb service until the company moved into its first office space. In April 2009, the company received $600,000 in seed money from Sequoia Capital and, in November 2010, raised $7.2 million in financing from Greylock Partners and, again, from Sequoia Capital, in a Series A round, then announcing that out of 700,000 nights booked, 80% had occurred in the previous six months.
