WeatherBill Incorporated, based in San Francisco, California, is a privately held firm that provides businesses across the United States with online weather forecasting, trend analysis, financial impact, and financial coverage tools and services. The company also offers clients rainfall pattern, climate change impact, and other research reports. The firm's platform allows businesses to analyze and manage risks associated with weather conditions. A company's financial information is uploaded to the WeatherBill Financial Report Analysis Tool. Information then is compared with data pulled from selected Weather Sensitivity Tool index stations. The firm maintains 200 stations across the United States. WeatherBill provides clients with extreme weather-based event planning, event monitoring, and impact analysis widgets. Employing online tools, clients customize and purchase weather-related contracts. Contracts are financial instruments, not insurance plans. Contracts, covering single weather events, are offered at varying prices. Payments are based on weather station measurements, which are audited by EarthSat. Settlements are processed automatically. WeatherBill has formed a risk capital agreement with fund management firm Nephila Capital. The alliance ensures that payments are made to counterparties. WeatherBill serves clients across the agriculture, construction, energy, financial services, retail, health care, manufacturing, wholesale, transportation, hospitality, real estate, education, and government sectors.
