5 Exciting Tech Innovations From SXSW Interactive 2015

Following on the heels of the controversial Robinhood launch, Acorns presents us with a financial app of a different kind. Rather than trading stocks for free, Acorns allows the user to automatically invest spare change from everyday purchases. This change is funneled into an optimized, diversified portfolio (said to be managed at all times by an expertly-developed automated process) with personalized risk levels, from "conservative" to "aggressive." And you? You sit back, relax, and watch the returns roll in. Only time will tell how effective this app will actually be, but the idea has certainly peaked our piggy bank's interest.
