One Concern is a Palo Alto, California climate-resilience analytics company that builds a digital twin of the built environment to quantify physical climate and natural-catastrophe risk in units of time rather than broad-brush hazard bands. Its Domino AI platform models the recovery of an individual building together with the lifelines it depends on — power distribution, ports, airports, roads and bridges, the surrounding residential community — and returns business-interruption downtime statistics, property-damage ratios and a 1CRX resilience score for a given latitude and longitude, per peril (flood, tropical-cyclone wind, seismic ground shaking, or all perils integrated), per return period or planning horizon, and under baseline or 2050 climate-change scenarios. The company sells to insurers, reinsurers, financial services and real estate, and exposes the platform to customers through the Domino AI API, a five-operation REST contract documented at developer.oneconcern.com and served from api.oneconcern.com behind a Tyk gateway with a customer-issued x-1c-api-token header.
