PredPol.
We make a web app that processes historical data for police departments (just time, place, type of past crime) and predicts where crime is going to happen in the future. Then cops go to the risky areas and try and stop a crime before it happens. Rails devs, iOS apps, please email me if you're looking for a job. We're growing too fast for our team of 4 to  handle while still sleeping well.
Everyone in the company works remotely, so there's no geographical excuse not to talk.
