The Story Behind OpenSummit

Our story is fairly simple. We wanted to create the best weather forecasts for the mountains, period.

This began when Joel Gratz and Andrew Murray created OpenSnow in 2011. OpenSnow has now grown to become the go-to resource for over 2 million skiers and riders around the world.

During the summer of 2015, Joel, Andrew, and Sam Collentine began sending out bi-weekly emails known as Trail Forecast. These consisted of weather forecasts and hiking tips for Colorado's 14,000-foot peaks, or as they're more commonly known, the 14ers.

Trail Forecast created a strong following during its first year. Instead of writing forecasts for general regions a few times per week, we wanted to make a product that could provide detailed hourly forecasts for each mountain.

During the spring of 2016, we started to plan for OpenSummit. This started with a few brainstorming sessions, and then we began working with Emerson Stone to create the flow, as well as the graphics and illustrations. And then finally we began building the back-end weather forecast calculations, as well as the first iOS app.
