About Apartment List

Apartment List is a rental marketplace built to simplify the renting process for tenants while connecting them to property managers and landlords. The platform curates and indexes over 6 million rental units and uses machine learning to match renters to suitable properties. Revenue flows from both renter-facing tools and B2B partnerships with property management companies. The organization operates across multiple geographies—hiring from the United States, Israel, United Kingdom, and Canada—with a balanced but engineering-forward team structure spanning product, data, sales, and marketing functions.
