What Ialert does

iAlert Services, LLC is a privately held U.S. weather intelligence company founded in 2010 in Rockville, Maryland, by former National Weather Service and NASA meteorologist Mark McInerney, who led the NWS Watch, Warning and Advisory program for nearly a decade and holds NASA's Exceptional Service and Exceptional Engineering Achievement Medals and the NWS Isaac M. Cline Award. The company operates two complementary product lines: iAlert, a push-based real-time weather alert notification service that delivers severe weather, lightning, forecast, observation, storm report, and hourly forecast alerts via email, SMS, and voice call across 30,000+ U.S. cities and towns; and WxData.com, a pull-based API providing developers and systems integrators direct programmatic access to NWS-sourced weather observations, forecasts, severe weather alerts, storm reports, and geolocation data in XML, JSON, and CSV formats. iAlert maintains a continuously updated archive of 1,011,723 storm reports and 970,188 NWS alerts since 2010, and has expanded beyond NWS coverage with proprietary real-time lightning strike detection added in 2026.

The company's business model combines a freemium consumer tier funded by advertising, paid subscriptions for ad-free service, developer-facing API subscriptions through WxData, and direct enterprise and government sales via the Group Manager (team/location subscription management) and Branded Alert Service (white-label distribution) add-ons. Customers span government agencies such as NYC Emergency Management, NYC Department of Homeless Services, and City of Ventura; energy operators such as Shell, Tennessee Valley Authority, and Missoula Electric Cooperative; transportation operators such as New Jersey Turnpike Authority and Active On-Demand; retail such as Albertsons/Safeway; financial services such as Texas Capital Bank; and technology services such as NTT Data. iAlert also operates a content marketing layer through the WxWaves podcast and Earth Science Network ecosystem to drive top-of-funnel acquisition.

The company is bootstrapped, has no disclosed outside funding, and operates with a 1-10 person team. Distribution is primarily domestic U.S. across all 50 states via self-serve sign-up at iAlert.com and API access at WxData.com, with no current international footprint. Marketing relies on organic SEO, an extensive weather blog, social media channels, and the WxWaves podcast, while a content-grade public weather analysis suite (radar, satellite, active alerts, observations, model analysis, hurricane tracker) supports both utility and SEO.
