What is Trust at Airbnb?

Airbnb is built on trust. Over two million people stay on Airbnb every night and the Trust Engineering team keeps our hosts and guests safe and supported throughout the entire Airbnb experience. We’re creating new relationships & placing people in vulnerable situations. Therefore trust is the fundamental currency of Airbnb. The Trust team builds trust by creating safety at every stage of the journey from the moment the user visits Airbnb. We set the standards & expectations for our community, keep bad actors out and and build products for good users to thrive without getting caught in the net.

We constantly work to fight against online fraud (through compromised accounts, spam and scam in messages, fake inventory, etc.) as well as preventing offline incidents (theft, property damage, personal safety, etc.). We work on onboarding and making accounts secure, and think about complex topics like identity, reputation, privacy, and anti-discrimination to ensure that every interaction with Airbnb helps build trust in us and our community. Trust Engineering is responsible for the technology vision and development of a complex stack that runs on every key interaction on the platform.
