About Gradon

Gradon is Legora for the firms that design the world's buildings and infrastructure. Every road, bridge, water system and building starts with engineers, and there aren't nearly enough of them for everything the world needs to build. Gradon works across every workflow and tool an engineering firm runs on, from CAD design and calculations to full plan sets, and firms using it today have decreased average project times by more than 75%. We're building the platform that makes every engineer a 10x engineer, and with it, how the world gets built.
