What WeatherSTEM does

WeatherSTEM Inc. is a privately held weather-intelligence company founded in 2014 in Tallahassee, Florida by Ed Mansouri, a former Weather Channel executive. The company sells professional-grade weather monitoring hardware stations paired with a cloud-based software platform to government agencies, universities, professional sports teams, and commercial operators that require hyperlocal, real-time environmental data for life-safety and operational decisions. The core product, the Protect station, is a professionally installed weather station with live HD camera and automated alerting, available in standard, Pro (solar/cellular), and Pro+ (hurricane-rated to 185+ mph wind) configurations; add-ons include the Blast outdoor warning siren and Bright weather-controlled lighting. The proprietary platform updates sensor data every 0.8 seconds (versus an industry standard of approximately five minutes), ingests dual-feed lightning detection (NLDN with AccuWeather backup), and integrates with National Weather Service alerts and major emergency management platforms including Everbridge, Esri ArcGIS, Noggin, and WebEOC.

WeatherSTEM generates revenue through a combination of hardware sales, recurring software subscriptions across three tiers (Lightning, Monitor, Cloud), white-glove professional installation included at no additional cost, professional meteorology services, and commercial data licensing of its aggregated station network. Pricing is custom quote-based with multi-year contracts and no public pricing tiers; the company has disclosed no revenue figures and no outside funding. Customers are concentrated in state and local emergency management (Florida Division of Emergency Management operates a 240+ station statewide mesonet; New Orleans OHSEP operates 26 stations), professional sports (New York Yankees, Jacksonville Jaguars), universities (Penn State, Texas A&M, Auburn), K-12 schools, and commercial operations including Southern Glazer's Wine & Spirits. Distribution is direct via field sales with named account contacts (e.g., Craig Ramsden, Director of Client Strategy), supplemented by an inside sales function and a self-serve Lightning software tier for organizations with existing sensor hardware. The company has installed 900+ stations across 30+ U.S. states, operates from Tallahassee, and remains founder-controlled following 11 years of bootstrap growth.

Strategic positioning centers on the bidirectional data-sharing relationship with the National Weather Service and on regulatory tailwinds such as the Texas UIL WBGT mandate for high school athletics, which the company is actively targeting. The April 2026 Weather Channel / NCAA Lacrosse coverage exemplifies the company's sports-vertical PR strategy. The 900+ station network functions as both a revenue-generating installed base and a proprietary data asset, with the Lightning self-serve tier and Starlink-enabled deployments signaling expansion into new geographies and customer segments without requiring proportional GTM spend.

Partnerships

Eight partnerships are on record, tiered emerging, flagship and core.

• Starlink (SpaceX)emergingTechnology or Integration · 18 May 2026Weatherstem completed first Starlink-connected weather station deployment in Liberty County, Florida. Satellite connectivity integration enables weather monitoring in locations without traditional cellular coverage, expanding deployment options for remote and coastal sites.
• Florida Division of Emergency Management (FDEM)flagshipStrategic or Co-development PartnerStatewide mesonet partnership deploying Weatherstem Protect Pro+ hardware across Florida's 67 counties. Florida's largest state-level weather monitoring network. Pro+ hurricane-rated hardware with solar/cellular for landfall events. State EOC anchors the network with county co-deployments sharing infrastructure costs.
• National Weather Service (NWS)coreTechnology or IntegrationBidirectional data sharing - Weatherstem stations share data with NWS regional offices to support their forecasting and analysis. Every Weatherstem station ingests NWS watches, warnings, and advisories and routes them through the same unified alert system as locally-detected conditions.
• EverbridgecoreTechnology or IntegrationNative mass notification integration. Weatherstem alerts route through Everbridge to staff and the public. Both systems share customer base in emergency management and government operations.
• Esri / ArcGIScoreTechnology or IntegrationStation data flows into Esri layers for clients using ArcGIS-based common operating pictures. Integrates into existing GIS situational awareness platforms used by EOCs and government agencies.
• NoggincoreTechnology or IntegrationBuilt-out integration for agencies running Noggin for incident management and EOC operations. Weatherstem data integrates directly into Noggin-based common operating pictures.
• NLDN (National Lightning Detection Network)coreTechnology or IntegrationPrimary lightning detection data source for Weatherstem's Practical Lightning Assistant. NLDN (operated by Vaisala) provides cloud-to-cloud and cloud-to-ground lightning strike detection across the United States.
• AccuWeathercoreTechnology or IntegrationSecondary live backup lightning data source. If NLDN feed goes down, AccuWeather provides continuity ensuring alerts never stop. Dual-feed redundancy is unique to Weatherstem in the outdoor warning industry.

Emerging players

• Davis Instruments: Davis Instruments manufactures weather stations spanning consumer, prosumer, and commercial markets with a large installed base of networked stations. Comparable hardware category to WeatherSTEM's Protect stations but with stronger consumer/prosumer and weaker enterprise/government focus.
• Tempest Weather Systems (WeatherFlow): Tempest is a networked, consumer/prosumer-focused weather station platform with growing enterprise applications in lightning and hyperlocal monitoring. Comparable networked weather station concept to WeatherSTEM but with a fundamentally prosumer distribution model.
• Kestrel Instruments (Nielsen-Kellerman): Kestrel Instruments manufactures portable weather and environmental meters used by athletic trainers, public safety, and field professionals. Comparable in serving the same end-user decision-makers (athletic staff, safety personnel) with environmental measurement, though in handheld form rather than fixed stations.

Broad incumbents

• Vaisala: Vaisala is the global leader in industrial meteorology instruments and operator of the NLDN lightning detection network that WeatherSTEM relies on for primary lightning data. Comparable as a manufacturer of professional-grade weather and environmental sensors, with broader industrial and aviation reach.
• DTN: DTN provides hyperlocal weather, agronomy, and operations intelligence across agriculture, energy, and logistics. Comparable in serving operationally-critical outdoor customers who need site-specific forecasts and alerting rather than regional data.
• Baron Weather: Baron Weather provides weather data, forecasting, and turn-key weather stations to broadcast, government, and enterprise customers. Overlaps with WeatherSTEM in emergency management and outdoor operations intelligence, with a broader media/broadcast footprint.

Direct peers

• Columbia Weather Systems: Columbia Weather Systems manufactures professional-grade weather stations for industrial, government, and commercial customers. Comparable as a hardware manufacturer of professional weather stations sold into similar industrial and institutional channels.
• Earth Networks (AEM): Earth Networks operates the Sferic Maps weather network with hyperlocal lightning, severe weather, and sensor data products serving enterprise, athletics, and government buyers. Highly comparable as a networked weather intelligence platform with enterprise SaaS and hardware components.
• Perry Weather: Perry Weather is a direct competitor in athletic, K-12, and outdoor safety weather monitoring — WeatherSTEM explicitly names Perry Weather in its competitive comparison. Both companies sell weather stations with automated lightning and severe weather alerting into schools, athletic programs, and municipalities with similar positioning.

Others

• AccuWeather: AccuWeather is a major commercial weather data and forecasting provider that also serves as WeatherSTEM's backup lightning feed. Adjacent rather than directly competing — AccuWeather supplies data infrastructure and forecast content that WeatherSTEM integrates, while also reaching end customers through media channels.
