It uses a proprietary WFM system to forecast demand across locations and automatically generate granular schedules, with a self-learning engine that adapts over time. Its edge comes from combining automated scheduling with employee engagement tools like flexible gig-style schedules, self-service, earned wage access, and rewards, all in one platform. The goal is to help businesses run labor operations more efficiently while improving satisfaction and productivity for the hourly workforce.
