Ultraleap do a surprising amount of interesting ML – mostly hand tracking from cameras - they had headsets to try and a cool screen ball pit demo thing.
They’ve got this interesting homebrew ML platform because they were shipping ML in a product early. It’s got some interesting features and a ton of stuff in it, so they’re having a fun time working out how to replace it, nothing modern quite fits. Maybe partly as they don’t have the normal model serving problem. They’re hiring across a surprising range of things.
