About Siren
Empowering NYC renters with data-driven insights since 2025
Our Mission
Siren aims to level the playing field for NYC renters by providing comprehensive, data-driven insights about potential rental properties. In a competitive rental market where landlords have access to detailed tenant histories, we believe renters deserve the same level of information about properties and their management.
By aggregating data from multiple public sources and using AI to generate meaningful insights, we help renters make more informed decisions about one of the most important aspects of their lives: where they call home.
