Data is essential to us at Airbnb. We characterize data as the voice of our users at scale. Thus, data science plays the role of an interpreter — we use data and statistics to understand our users and translate it to a voice that people or machines can understand. We leverage these quantitative insights, paired together with qualitative insights (e.g. in-person user research) to make the best possible decisions for both the business and our community of hosts and guests.
