I’m convinced that there’s never been a better time to build compelling and novel privacy businesses. My recent at-bat may be compelling but it’s not novel; the goal was simply to improve the user experience of a widely deployed security technology. Evolutionary enhancements are valuable and necessary, but I suspect the space is ripe for revolution. One question that seems to be at the tip of our collective tongues is how (and when) to move personal data out of central stores and back to edge devices under our control. There are many verticals where the benefits of such a move appear to be substantial and where there seem to be no fundamental economic or experiential arguments against. But I keep wondering if there’s a deeper horizontal play to be found. I consider it an accident of recent history that today’s personal data typically lives far from home. A business that builds a platform (and hardware?) to enable a privacy-local future might plausibly power an online revolution.
