Beth Kolko's superpower may not seem that out of the ordinary. She can't see through walls, but she can see what's wrong with the things we use in everyday life — problems that never occurred to the experts who built them. As the CEO of medical device maker Shift Labs, Kolko has focused that superpower on health care. Specifically, she wants to solve the problems that arise when an industry makes medical devices almost exclusively for patients in hospitals in rich countries and ignores almost everyone else.
