The Origins of Keysill
Our Story
KeySill’s founder Aaron Reay, previously president of 406 Window Co., saw firsthand how the misalignment between architects’ designs and the on-site execution caused frustration, delays, and lost productivity. His goal was to streamline the entire process by creating a tool that brought the teams together.
The result was KeySill, a way to translate architectural ideas into clear, actionable instructions that anyone can follow.
