First Street

Founded in 2016 and headquartered in Brooklyn, USA, First Street (also known as First Street Foundation) is a non-profit research and technology group specialized in climate risk financial modelling and intelligence. Its modeling framework draws on deterministic, hazard‑specific simulations that estimate exposure to flooding, wildfire, extreme heat, wind, and other perils across present and future climate scenarios. First Street’s modelling approach is transparent and peer‑reviewed, integrating validation against observed historical events and enabling independent evaluation by external economists, climate scientists, and engineers
