WSI Corporation

What WSI Corporation does

WSI Corporation, operating as The Weather Company, is a wholly-owned subsidiary of IBM that provides commercial weather intelligence across consumer, enterprise, and data channels. Founded in 1978 and headquartered in the United States, the company combines numerical weather prediction, AI/ML-driven ensemble modeling, and expert human meteorologists to produce approximately 25 billion forecasts per day for 2.2 billion global locations. Consumer distribution runs through The Weather Channel, Weather Underground, and Storm Radar apps plus weather.com, reaching 50 million-plus monthly users across 178 countries and 83 languages. Enterprise offerings span the Maverick aviation suite (Dispatch, Ground Ops, Pilotbrief, WXAlert, Fusion) and the Max media suite (Cloud, On Demand, Alert Live, ReelSphere, One Pro, Studio, Storm, and additional on-air/graphics modules), sold via direct B2B sales to airlines, airports, broadcasters, and station groups. Data solutions include Weather Data APIs handling roughly 2.5 billion calls per month at a 99.9% uptime SLA, plus a Weather Agent for Indices & Triggers product for programmatic weather-based actions. Advertising solutions monetize the same data via weather-triggered targeting, premium formats, sponsorships, and audience targeting across owned consumer inventory.

Revenue is generated through four interlocking streams: enterprise subscriptions for aviation and media customers, tiered API subscriptions with usage-based billing, premium consumer subscriptions for ad-free and bundled perks in The Weather Channel app, and advertising revenue from weather-signaled contextual targeting. The company operates a multi-channel go-to-market — direct enterprise field sales for aviation and media, app-store and web distribution for consumer, and developer/API self-serve with a free trial funnel for data products. Underlying technology is built on the proprietary GRAF (Global High-Resolution Atmospheric Forecasting) model and JEDI forecasting system, run on AWS infrastructure, with documented third-party accuracy leadership (4x more likely the most accurate forecaster, ForecastWatch 2021-2024) and structural data advantages (89% user opt-in for location, 100K+ enterprise customers).

The Weather Company operates as a strategic business unit within IBM's broader enterprise AI and cloud portfolio, leveraging IBM Watson since 2015 for analytics integration. Strategic priorities evident from recent activity include aviation vertical deepening (Maverick Dispatch, 2024), advertising monetization expansion amid cookie deprecation, MITRE partnership for global intelligence R&D, and sustained investment in proprietary modeling infrastructure. Headcount of 1,001–5,000 supports the multi-segment operating model.
