I am talking about LiveBolt, the winners of the Tech Crunch Disrupt hackathon. For only $60, you get a mount that integrates with your door's deadbolt and you can get entry-level home automation. In only a few hours, this team was able to ship an MVP that provides instantaneous home automation. The value proposition here is that you can easily get into your house without using keys (which are annoying to have... I'd rather use my iPhone to unlock/lock things).
The future is bright as we continue to hack together solutions that bring value -- I always emphasize "hack" as a way of describing a solution with a short time-to-market and obvious value proposition. Infrastructure costs and hardware costs are going down which allows us to pave the way to the future with innovation and creativity.
Keep hacking away and solving problems!
