This document provides an introduction and background to hostelbench, a benchmarking service for hostels. It discusses the history of benchmarking, beginning with its origins in cobblers measuring feet and Xerox formally introducing the practice in the 1980s. The document then covers how benchmarking has evolved in the hotel industry through services like STR Global. It introduces hostelbench as seeking to provide a similar benchmarking service tailored to the hostel industry, allowing hostels to submit occupancy, rate and revenue data anonymously to generate performance reports. The intended benefits are to help hostels make more informed operational and pricing decisions through industry comparisons.
