Long wait times for patients can be the undoing of a large clinic or a hospital system. According to a recent survey, 84% of patients consider a reasonable wait somewhat or very important to a quality experience, and 30% say they've left a medical appointment because of an inordinately long wait. And a whopping 20% of patients say they'd consider changing providers due to wait times alone. That's why Mohan Giridharadas, a Stanford graduate and former McKinsey and Company partner, founded Charlotte, North Carolina- and Santa Clara-based LeanTaaS. It's a predictive analytics company that taps data science to "radically" improve health care provider performance, using cloud-based solutions to solve problems like resource utilization.
