In this Jan. 10, 2017 photo, Adrian Aoun, founder and CEO of Forward, left, gives a demonstration of a vein illumination device that uses infrared light on an Associated Press reporter at a medical office in San Francisco. After a relative suffered a heart attack a few years ago, Silicon Valley entrepreneur Aoun got an up-close look at a health-care system that he diagnosed as an inefficient and outdated mess. Now, Aoun is ready to prescribe his remedy. It's called Forward, a health-management service that charges a $149 per month, roughly $1,800 a year, to tend to all of its patients' primary-care needs.
