Ask HN: Cool technology oriented startups/young companies.

Most of the companies advertised/discussed on HN, are consumer oriented. So, there's very little cool brand new technology used there. Basically what they do is to just take existing hipster web/MVC framework, optionally invent disruptive business model to change existing market. Most of them disrupt in the area of business models not technology. Which young technology companies/startups you know which are mostly technology oriented and which can disrupt the market in the near future? Here's my list: * Oculus VR * FP Complete * Meteor
