"Dedicated to the improvement of every curler's game through technology that's as precise as the sport itself."
Founded in Grand Rapids, Minnesota, Curlvation was born from a passion for the sport and a belief that technology could make it better. We combine deep curling knowledge with modern engineering to create tools that solve real problems on the ice — whether you're timing a delivery, reading ice conditions across the sheet, or measuring stone placement with precision.
Our products are designed to be practical, durable, and intuitive — because the ice doesn't wait and neither should your tools.
Time your stone deliveries with precision and instantly understand where the rock will end up. RockTimer gives sweepers the data they need to make real-time decisions, taking the guesswork out of every shot.

Learn MoreWe don't build generic sports tech. Every Curlvation product is engineered around the specific demands of curling — the physics of the stone, the chemistry of the ice, and the split-second decisions that determine the outcome of every end.
Our products are designed by people who understand curling — not adapted from general sports tech. Every feature solves a real problem that curlers actually face.
