Who we are: First Street is the standard for Climate Risk Financial Modeling. We use transparent and peer-reviewed methodologies to calculate the past, present, and future climate risk for every property in the world. We started working with the world’s leading climate scientists to create groundbreaking, climate-adjusted, property specific models over 8 years ago and haven’t stopped.
Our mission: We exist to connect climate and financial risk.
Our data: We create physics-based, deterministic models of flooding, wildfire and hurricanes, and advanced statistical models of extreme heat, air quality, drought, hail, severe convective storms, winter storms, and more. All of this data is used to create property-level financial risk metrics and macroeconomic variables to quantify the impacts of climate, property by property.
Our customers: We empower governments at the highest levels to make smart regulations, businesses to avoid bad investments, and everyday homebuyers to understand their personal risk from climate change. We are relied on every day by:
Agencies ranging from the U.S. Department of Treasury to Fannie Mae
The world's biggest banks such as Bank of America and Wells Fargo
Institutional investors like Nuveen and Blackstone
Millions of everyday users on Zillow, Redfin, Realtor.com, Homes.com, and more
We believe: With the right data, we can identify the problems, avoid bad investments, and implement solutions. This is why we have invested tens of millions of dollars into our science, data, people, and products and have raised tens of millions more to move even faster.
