Humanalytics Ltd. is a technology company that specialises in improving worker productivity and wellbeing. By using smartwatches and machine learning we measure the wrench time (time on tools), activity, and wellbeing of front line workers and provide insights into how these can be improved per site. We also generate live duress and man-down alerts should the front line worker be at risk. Business productivity in industries, such as construction, manufacturing and warehousing, can be improved by up to 10% using our technology. These industries face the challenge of declined productivity of front-line workers, impacting the bottom-line. For example, major infrastructure projects, typically take 20% longer to finish and go up to 80% over budget, resulting in billions of dollars lost annually. Humanalytics solves this productivity challenge.
