What OpenSnow does
OpenSnow (legal entity Cloudnine Weather, Inc.) is a Boulder, Colorado-based subscription weather forecasting platform founded in 2010-2011 by Bryan Allegretto and Joel Gratz, targeting skiers, snowboarders, and snow sports enthusiasts who require highly location-specific mountain weather forecasts. The core product is the OpenSnow application, distributed via iOS App Store, Google Play, and direct web signup, offering Base ($49.99/yr individual, $89.99/yr for up to four people) and Premium ($99.99/yr individual, $179.99/yr family) annual subscriptions with a no-credit-card free trial and automatic renewal. Forecasts are generated by PEAKS, a proprietary AI-powered model that processes government weather data and learns from past storms to deliver location-specific mountain terrain forecasts at a claimed 50% accuracy improvement over the prior system. Severe weather alerts are delivered via the acquired StormNet platform, and the company is developing AI-powered avalanche forecasting features. OpenSnow serves a long-tail consumer base of roughly 500,000 users globally, supplemented by institutional relationships such as the Ski California partnership covering 36 ski areas, and operates as a private, bootstrapped company.

OpenSnow competitors and assessment
Company assessmentDirect peers
- Snow-Forecast.com: Mountain and ski-resort weather forecasting site offering multi-model snow predictions for ski areas worldwide. Directly comparable to OpenSnow as both target skiers/snowboarders seeking elevation-specific forecasts and are explicitly benchmarked against each other on OpenSnow's own 'How We Stack Up' page.
- OnTheSnow: Snow reporting and ski conditions platform providing daily snow reports, webcams, and forecasts for ski resorts globally. Direct competitor in the ski-conditions vertical and explicitly listed by OpenSnow as a benchmark competitor.
- Windy (Windy.com): Interactive weather forecasting platform with rich global map visualizations and multi-model comparisons. Comparable because it serves enthusiast outdoor users with hyperlocal forecasts and is explicitly benchmarked against OpenSnow.
- Mountain Forecast: Mountain-specific weather forecasts for peaks and ski areas worldwide, including elevation-layered forecasts. Directly comparable niche player serving the same skier, climber, and mountaineer personas.
Broad incumbents
- The Weather Channel: Mass-market weather platform from IBM-owned The Weather Company with national and global forecasts, precipitation maps, and severe weather alerts. Comparable as a broad incumbent OpenSnow explicitly benchmarks against, with overlapping general-forecast functionality.
- Apple Weather: Default weather service bundled across iOS, iPadOS, macOS, and watchOS, with increasing investment in hyperlocal and severe-weather features. Comparable broad incumbent that OpenSnow explicitly benchmarks against and that pressures OpenSnow's pricing on Apple devices.
- National Weather Service (NOAA/NWS): U.S. government source for free, authoritative public weather forecasts and alerts. Comparable because it provides the underlying data many forecast products rely on and is the dominant free alternative OpenSnow is benchmarked against.
- Weather Underground: Consumer weather platform leveraging personal weather station data and forecasting APIs. Comparable broad incumbent offering consumer-grade forecasts with overlapping functionality for OpenSnow's user base.
Emerging players
- Powderchasers: Snow forecasting and powder-alert service for skiers focused on storm tracking and trip planning. Comparable emerging niche player targeting the same powder-hunter persona as OpenSnow's most engaged users.
