Ask venture capitalists in Silicon Valley about which industry they're most excited to revolutionize, and odds are high that they'll say health care. So it's no surprise that money is surging into start-ups that focus on the intersection of health care and technology. In 2014, venture funding for these start-ups hit a record $4.1 billion. That was a 125 percent year-over-year jump, according to Rock Health, which provides seed funding for start-ups and conducts research in this area. Those working in this sector say health care is undergoing a technology transformation with a range of start-ups aiming to make the industry more efficient, convenient and cost effective.
