What Ventusky does
Ventusky is a Czech-based weather visualization platform founded in 2015 and operated by Ventusky, s.r.o., headquartered in Plzeň. The company's core product is an interactive weather map that aggregates data from multiple numerical weather prediction models — ECMWF, GFS, ICON, GEM, and HRRR — and overlays supplementary layers including satellite imagery, air quality (via AQICN), radar with AI-based nowcasting, and a network of 30,000+ ground webcams. In April 2026 the company extended this surface with a Global Fire Monitoring layer fusing satellite detections from NASA FIRMS, EUMETSAT MTG, and JMA Himawari with officially reported fires from US, Australian, and Canadian firefighting agencies.
The company runs a product-led freemium go-to-market: the core visualization platform is free on web, iOS, Android, Apple Watch, and Wear OS, while paid Premium (up to 4 devices) and Premium+ (up to 25 devices) tiers unlock unlimited layers, forecasts beyond 7 days, advanced widgets/notifications, and priority support. Subscriptions are billed annually via Paddle on web, Apple App Store on iOS, and Google Play on Android; voucher codes are distributed to rescue workers, educators, and influencers. The company has no public API but offers an embeddable iframe (embed.ventusky.com) used by tier-1 publishers including the Daily Mail, El País, CNN Prima News, The Washington Post, The Mirror, Le Télégramme, Libération, and Metro for hurricane, storm, and jet-stream coverage.
Ventusky is privately held and self-described as bootstrapped — funded solely through subscription sales with no disclosed venture capital, private equity, or institutional investment. Ownership commentary emphasizes organic growth; no parent company, subsidiaries, mergers, acquisitions, or leadership changes are recorded. The company is GDPR-compliant and active operationally across web, mobile, wearables, and editorial distribution.

Ventusky competitors and assessment
Company assessmentDirect peers
- Weather Underground: Weather Underground provides consumer weather forecasts, interactive maps, and a large network of personal weather stations — directly comparable to Ventusky's consumer weather visualization offering.
- Meteoblue: Meteoblue is a Switzerland-based weather service offering high-resolution forecasts, interactive maps, and subscription tiers — closely comparable to Ventusky in product scope, geographic focus (European origins), and target customer (outdoor enthusiasts, pilots, agriculture).
- Windy.app: Windy.app is a mobile-first weather forecast service targeted at outdoor sports enthusiasts (sailing, kiting, fishing, paragliding) — directly comparable to Ventusky's outdoor enthusiast use cases around wind, waves, and conditions.
- Windy (Windytv): Windy is the closest direct competitor to Ventusky, offering interactive multi-model weather visualization with similar forecast models (ECMWF, GFS, ICON) and a freemium subscription model targeting weather enthusiasts and outdoor users globally.
Emerging players
- Zoom Earth: Zoom Earth provides interactive weather maps, satellite imagery, and storm tracking — a more narrow visualization tool that overlaps with Ventusky's satellite/radar/fire monitoring layers but without Premium subscription or multi-model aggregation.
- Tomorrow.io: Tomorrow.io (formerly ClimaCell) is an emerging weather intelligence platform combining forecasts with proprietary sensing for enterprise use cases (aviation, logistics, on-demand) — competing with Ventusky's data-driven approach while targeting B2B more aggressively.
Others
- National Oceanic and Atmospheric Administration (NOAA): NOAA is a US government agency that produces the GFS and HRRR forecast models and weather.gov consumer site — directly comparable as an upstream data provider and free public alternative whose terms-of-use and product decisions shape Ventusky's offering.
Broad incumbents
- AccuWeather: AccuWeather is a large incumbent weather data and media company offering consumer forecasts, enterprise APIs, and licensed data products — competing with Ventusky for end users while operating a much broader B2B data and advertising business.
- The Weather Channel (IBM): The Weather Channel, owned by IBM, combines consumer weather media (weather.com, app) with IBM's enterprise weather data business (Environmental Intelligence Suite), overlapping with Ventusky on consumer weather visualization but with far broader enterprise reach.
Regional players
- Yr (Meteorologisk institutt / NRK): Yr is a free weather service from the Norwegian Meteorological Institute and NRK, popular across Scandinavia — comparable in consumer weather visualization to Ventusky but regionally focused and free without a Premium tier.
