Big data for your personal life. Only one problem: Big data is amazingly hard to get valuable insight out of. Correlation is relatively easy, but causation? Not so much. Actually, even if the data isn't big, it's still _really_ hard to figure out causation. If exist.io does make it, It'll be because they figure out just ONE kind of reliable causative relationship they pull out of their data, and they figure out how too monetize that.... This is actually a pretty clever way to crowdsource THAT process though...
