First Street operates at the intersection of climate science and financial risk, providing what it describes as the standard for Climate Risk Financial Modeling. The company quantifies and communicates climate risk for every property in the United States, using physics-based deterministic models to predict the likelihood of floods, wildfires, hurricanes, and other hazards, along with associated damage and downtime. Its data serves institutional investors such as Norges Bank Investment Management and Blackstone, banking enterprises including Bank of America and Fifth Third, and government bodies ranging from Fannie Mae to the US State of Connecticut, as well as millions of individual users.
The technical work draws on climate science, economics, and physics-based modelling. The team includes leading climate scientists and economists, and the company emphasises transparent, peer-reviewed methodologies. Its modelling approach applies to asset classes spanning real estate, infrastructure, and companies.
First Street is backed by Innovation Endeavors, Galvanize, and General Catalyst. Its geographic reach extends globally, though its detailed property-level coverage is concentrated in the United States. The company operates across financial institutions, banking, investment, real estate, infrastructure, and government sectors.
