Castlight Health [is a] nascent health care start-up…with the goal of giving insurance subscribers meaningful information on health care costs. Castlight, in the simplest terms, wants to bring comparison shopping to health care.
It launched, last year, a Web site where employees on [Health Saving Account] plans can compare what doctors charge for the same service. The site…also includes other patients’ quality rankings of doctors, alongside information on what remains in an individual’s account.
