The snow gods: How a couple of ski bums built the internet’s best weather app

OpenSnow is an independent weather app startup that uses government data, custom AI models (machine learning systems that learn patterns from data), and expert knowledge to provide better snow and avalanche forecasts than major weather services, becoming essential for skiers and snowboarders worldwide. Founded by two ski enthusiasts, Bryan Allegretto and Joel Gratz, the app grew from a 37-person email list to half a million followers by offering detailed daily snow reports and micro-accurate predictions, especially during unusual winter conditions.
