What Weatherflow does
WeatherFlow-Tempest, Inc. is a private weather technology company headquartered in Daytona Beach, Florida, that builds and operates a dense network of Tempest weather stations paired with patented Nearcast AI™ forecasting technology to deliver hyper-local, point-specific weather intelligence. The company monetizes through four primary revenue streams: (1) consumer hardware sales of Tempest weather stations and accessories through shop.tempest.earth; (2) B2B SaaS subscriptions to the TempestOne professional platform for organizations in emergency management, media, utilities, transportation, and sustainability; (3) Data-as-a-Service offerings to property, wildfire resilience, and climate decision-support sectors; and (4) API services for developers and enterprise integrations. Beyond its owned Tempest stations, the company benefits from an exclusive data arrangement with affiliate WFn Holdings Inc. (WeatherFlow Networks), which operates the largest industrial-grade private weather observing network and supplies data to NOAA and the Hurricane Insurance Industry.
The go-to-market is hybrid: product-led growth for consumers via direct e-commerce and a lifestyle app portfolio (iKitesurf, iWindsurf, SailFlow, WindAlert, FishWeather, HeatAlert), and enterprise field sales for TempestOne supplemented by event presence (EMAT Workshop, NAB 2026) and broadcast, smart home, and integrated partner channels. Verticalized B2B modules — T°One for Utilities and T°One for Coastal — extend the platform beyond generic data into sector-specific operational intelligence, while a Kentucky Derby hyper-local use case demonstrates the technology's resolution for high-stakes, risk-sensitive applications. The company is privately held, employs 51-100 people, and has raised approximately $8.88 million across four funding events between May 2022 and February 2025, including a $3 million growth capital round led by WindSail Capital Group in December 2024.
