WFn Holdings

What WFn Holdings does

WFn Holdings Inc. (WeatherFlow Networks) is a private U.S. operator of the world's largest industrial-grade private mesoscale weather observing network (mesonet). Founded in 1998, the network comprises more than 500 stations along the Atlantic, Pacific, Gulf, and Great Lakes of the United States and Canada, reporting as frequently as every minute. The infrastructure includes 100 hurricane-hardened stations (HurrNet) rated to survive winds up to 140 mph, allowing 100% operational success across the past 15 hurricane seasons. The stations are built around proprietary Scylla data loggers paired with best-in-class commercial sensors, supplemented by remote sensing assets including SODAR and LIDAR profilers for hub-height wind measurement.

The company serves a specialized B2B and government customer base, including NOAA and the National Weather Service, the hurricane insurance industry, wind energy operators, emergency management agencies, civil engineering firms, and academic research institutions. Go-to-market is enterprise field sales, with offerings including customized data streams, professional installation and maintenance services, and specialized network deployments. Revenue is generated through data licensing and streaming, recurring subscription applications, specialized network services, and parametric catastrophe risk transfer products (WindX). Pricing is not publicly disclosed and is custom to each customer's requirements. In January 2019, the founders spun off WeatherFlow-Tempest Inc. to pursue the consumer and SMB markets through apps, SaaS tools, and APIs, while WFn Holdings retained ownership of the ProNet infrastructure to serve government, insurance, and energy clients directly.

Direct peers

• WeatherFlow-Tempest Inc. Affiliate entity founded in 2019 by the same WeatherFlow Networks founders to commercialize ProNet data via consumer apps, SaaS tools, and an API. Operates the global Tempest Network and now serves the majority of customers that ProNet data underpins, making it the closest commercial peer even though it is also a customer/channel.
• Earth Networks: Operates the WeatherBug network of thousands of weather observation stations and provides commercial weather data, lightning data, and decision tools to enterprises, media, and government — directly comparable to WeatherFlow's mesonet data licensing business.

Broad incumbents

• Vaisala: Global leader in weather, environmental, and industrial measurement instrumentation including road and airport weather stations. Comparable as an incumbent that supplies the underlying sensors and observation networks used by national weather services and aviation/energy customers, overlapping with WeatherFlow's hardware and data business.
• Campbell Scientific: Designs and manufactures rugged data loggers (e.g., CR-series) and weather station systems used in research, agriculture, and government observation networks — overlapping with WeatherFlow's Scylla data logger and station hardware business.
• DTN: Delivers weather-driven operational intelligence for agriculture, energy, aviation, and commodity markets — directly comparable to WeatherFlow's wind energy and risk-transfer customer use cases, with broader commodity coverage.
• IBM Environmental Intelligence Suite (The Weather Company): Offers enterprise weather and climate data, including observations from a large global network, packaged into APIs and analytics — comparable as a large-scale weather data provider competing for the same enterprise/government contracts.

Emerging players

• Tomorrow.io (formerly ClimaCell): Provides high-resolution, API-first weather and climate data combining signals from satellites, IoT devices, and proprietary sources for enterprise use cases in aviation, logistics, and energy — comparable as an alternative data platform competing for the same enterprise weather data spend.
• Davis Instruments: Manufactures professional and prosumer-grade weather stations and data loggers (Vantage Pro series) widely used by hobbyists, agriculture, and small enterprises — comparable hardware/data overlap with WeatherFlow's lower-end sensor business, though without the mesonet-scale network.
• Baron Weather: Provides weather data, radar, and forecasting services to broadcast, government, and enterprise customers, including critical weather intelligence for public safety and aviation — overlapping with WeatherFlow's severe weather and government verticals.
• Understory: Deploys proprietary ground-based weather sensor networks focused on hail and severe convective weather for insurance and agriculture — directly comparable niche weather observation network business serving insurance risk transfer, similar to WeatherFlow's HurrNet and WindX focus areas.
