Data visibility is your friend
Castlight aims to do as its name suggests: cast light on the actual costs of medical care, so that people can make informed decisions. The company, founded in 2008 by entrepreneurs Giovanni Colella and Todd Park, now chief innovation officer for the U.S. Department of Health and Human Services, offers computer-based tools that let people comparison shop for health care in much the same way they would for airline tickets on Travelocity or for cars on Cars.com.
The company sells its tool to self-insured employers, who pay a fee per covered member per month, and in turn offer employees access so they can become more responsible users of their benefits. It has raised $81 million in venture funding to date. Current customers include Safeway and Life Technologies, a leading maker of genomics tools.
