Genda is construction site managers personal assistant. Using sensors and computer vision we create real-time data about site resources automatically, analyze the data using machine learning and lean principles, eliminating waste in the process and saving a great amount of money. With Genda, site managers can make decisions based on real-time reliable data instead of gut feelings. Genda creates real-time project status, alert about waste in the construction project, improve site safety, and marks what is the next task that should be executed.
