Really no flutter on this list? These are all great companies but I think flutter deserves a spot as a company with potential to really change how we interact with our devices. It seems like one of the few that is inventing a new space rather than improving on one that already exists (not that there's anything wrong with that).
Agreed. The other one that seemed to fall into/near this category was MatterPort http://matterport.com/ They seem to be utilizing a Kinect for capturing texture-mapped point clouds of indoor environments and objects. If it really does this, with true-to-size dimension measurements, this will be an incredible tool for "surveying" physical objects and spaces.
For those of you who've read joshua foer's 'moonwalking with einstein' about memory competition and memory palaces, I thought this could be a great platform to create an app that builds and maps memory palaces out of your own physical spaces (like your house, friend's houses, office, etc) and uses the maps it creates to train your memory (so you too can memorize the order of two decks of cards in five minutes).
