Airbnb has rapidly become central to the world of corporate travel, a major feat in an industry that is often resistant to change.

Airbnb for Work launched in 2014, and now over 500,000 companies use it for travel. It offers centralized billing tools, notes for expensing purposes, and company administration dashboards, as well as options to book meeting spaces and team-building experiences.

Airbnb for Work has made attempts to crack into the event industry, including releasing a tool for meeting planners and group travelers and acquiring event space booking tool Guest, but the impact has been small.
