When you start your career as one of the first employees at Yahoo and go on to launch photo tagging at Facebook, what do you do next? For Doug Hirsch, the answer came from looking around for the most challenging problem to solve next. In 2010, after being quoted an outrageous price for a prescription, he had the idea for GoodRx - a company that now provides millions of Americans with affordable and convenient access to prescription medications. GoodRx is now the #1 rated medical app and has a $2.8 billion valuation. Doug shares why he's obsessed with solving messy problems, the importance of blocking out time each day for thinking, and how he views his career through the lens of wanting to make the world a better place.
