Upper School student Nicholas P. ’26 launched Powderline, a mobile app and website designed to help skiers and snowboarders navigate real-time mountain conditions and plan their time on the slopes.
Following a year of development, the app launched in March in partnership with the United States of America Snowboard and Freeski Association during its annual National Championships. As the primary development pipeline for Olympic athletes like Shaun White, Chloe Kim, and Eileen Gu, the organization’s adoption is a major milestone, with athletes, coaches, and families using it to track conditions and optimize their time on the mountain.
The idea grew out of Nicholas’s experience as a competitive snowboarder. After years of navigating fragmented sources for weather, snow conditions, and logistics, he set out to build a single, reliable product that could deliver clear, dynamic information in one place.
The app’s core feature is the POW Score, a 0–100 rating evaluating conditions such as new snowfall, base depth, temperature, wind, and visibility. It also provides mountain-specific forecasts from aggregated weather models, private group features for real-time coordination, and integrated competition data. The platform currently supports more than 170 resorts worldwide.
Nicholas built Powderline independently, developing the iOS and Android apps, website, backend, and data systems himself. Launching the product required both technical expertise and careful problem-solving around data accuracy, particularly in reconciling discrepancies between reported and actual mountain conditions.
“The mountains have given me some of the best moments of my life, and Powderline is my way of giving that back,” Nicholas shared. “I hope it becomes the first thing skiers and riders open in the morning and the last thing they check before bed.”
Sierra Canyon’s entrepreneurial programming encourages students to think creatively and take initiative. By fostering forward-thinking and innovation, they develop the skills and confidence to create solutions with meaningful impact in the wider world.
