What OpenWeather does

OpenWeather, founded in 2012 and headquartered at The Gherkin in London with additional offices in Paphos, Cyprus and Lewes, Delaware, is a private weather intelligence company that provides modular environmental data products to enterprises, public-sector organisations, and developers. The company's portfolio combines data APIs (Current & Forecasted Weather, Historical Weather, Weather Maps, One Call API), operational dashboards (Weather, Energy, Extreme Weather), add-on modules (Solar Irradiance, Wind Forecast, Road Weather Intelligence, Fire Weather Index, Lightning, Air Pollution, Pollen, Climate Indices), professional-grade OWS hardware stations (Automatic Weather Stations, Air Quality, Portable, Agro), and expert meteorology services. The core technology layer is the proprietary OWHL™ Hyper-Local Model, an ML-powered forecasting engine delivering 100m resolution forecasts with 10-minute updates, fed by ingest partnerships with the UK Met Office, NOAA, ECMWF, JMA, and the Australian Bureau of Meteorology, and complemented by an AI Weather Assistant launched in July 2025 and One Call API 4.0 launched in June 2026.

The business operates through two distinct go-to-market motions: an enterprise/field sales channel targeting corporations and public-sector buyers (enterprise pricing starts at £3,000/month with multi-year contracts, procurement-ready terms, and onboarding) and a developer/self-serve PLG channel through openweathermap.org with freemium and paid subscription tiers. Distribution is reinforced by IT solution provider partnerships (SHI, CDW, SoftwareOne), public procurement framework accreditation (ESPO Weather Forecasting Services Framework 118, awarded October 2025), trade body memberships (LCRIG, ADS Group, ITS UK, Achilles UVDB), and channel procurement platforms (SAP Ariba, Coupa, Dun & Bradstreet). Revenue streams span enterprise subscriptions, API/data subscriptions, hardware sales, professional services, bulk data delivery, and managed vertical-specific solutions across energy, logistics, agriculture, defence, insurance, retail, health, advertising, construction, emergency services, and public authorities.

Operationally, OpenWeather serves 190+ countries and territories with 99.9% platform uptime and counts Microsoft, Amazon, Google, Airbnb, Booking, TomTom, Facebook, Accenture, BP, PepsiCo, Chevron, Alstom, Bayer, Barnes & Noble, HILTI, Fossil Group, B2C Innovation, INDOMET, and Terega among its named customers. The company maintains ISO 27001 and ISO 9001 certifications, is led by directors Denis Ukolov and Olga Ukolova with Arkadiy Ukolov in business development, and operates a parallel non-profit OpenWeather Foundation supporting 8,000+ students and 500+ universities globally. The company is founder/management-owned with no disclosed external funding rounds.
