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.

Our Data

Siren aggregates data from multiple sources including:

NYC 311 Complaints

We analyze 311 complaint data to identify patterns of tenant issues such as heat/hot water problems, pests, and building maintenance concerns.

HPD Violations

Housing Preservation & Development violation records reveal how well a building complies with the housing maintenance code and multiple dwelling law.

Our Technology

Siren uses advanced AI technologies to analyze building data and generate human-readable insights. Our platform:

  • Processes thousands of complaints and violations to identify patterns
  • Compares buildings to neighborhood averages
  • Generates comprehensive insights with actionable intelligence
