Health care startups have boomed over the last several years, as evidenced by the number of venture funding deals, which grew some 200% between 2010 and 2014. The boom is driven by health reforms that are disrupting business models, an aging population that's demanding more (and better) care, and the adoption of technology — such as wearables and video chat — into the medical mainstream. Add to that boom the fact that it's a golden age for entrepreneurship, where the declining cost of technology means more entrepreneurs than ever have the tools to build new companies, and you have all the ingredients for a startup revolution in health care.
