Weather Source

What Weather Source does

Weather Source, now operating as Pelmorex Weather Source following a 2024 rebranding under Pelmorex Corp, is a Salem, NH-based weather and climate data company providing analytics-grade hyper-local weather data to enterprise customers across retail, logistics, energy, finance, and adjacent verticals. The company operates the patent-pending OnPoint Platform, which ingests, cleanses, and processes weather observations from satellites, radar, weather stations, and IoT sensors, then stages the data on a globally consistent 5-kilometer resolution grid (the OnPoint Grid) covering every land mass and up to 200 miles offshore. North American locations are never more than 2.2 miles from an OnPoint ID, and the data is continuously quality-controlled to deliver gap-free, error-corrected outputs engineered for immediate machine learning analysis.

The product portfolio is organized around four core OnPoint products — Weather, Climatology, Geospatial, and Risk Analytics — delivered via the OnPoint RESTful API and distributed through direct enterprise sales, a free 30-day developer trial, and strategic marketplace and BI partner integrations with Snowflake, S&P Global, Google Cloud (BigQuery), Looker, Qlik, CARTO, 1010data, Knoema, Datarade, Eagle Alpha, BattleFin, Crux, and others. Add-on solutions include the Dynamic Weather Alerting Service (DWAS) for real-time notifications, the Weather Insights Platform (WIP) for retail/restaurant sales forecasting using ML, and Condition-Based Ad Triggering (C-BAT) for weather-based marketing automation integrated with Google DV360, GAM, and Meta Ads.

The company operates a primarily API-first, subscription-based revenue model with quote-based enterprise licensing, professional services on a statement-of-work basis, and marketplace-driven data monetization. Named enterprise customers span multiple Fortune 500 organizations (Ford, Honeywell, Target, AT&T, DHL, Danone, Bloomberg, Jefferies, Evergy, Warner Bros, HomeAdvisor, Ecolab), indicating diversified but enterprise-weighted revenue concentration. As a privately held Delaware LLC subsidiary of Pelmorex Corp, Weather Source combines its data assets with the parent's 35+ years of weather expertise and 40 million monthly users.
