After DREEM and Philips, there's another neurotech company popping up with an acoustic stimulation headband called TRANCE. Their headband will also be the first one to include binaural beats, an idea that I wanted to test for sleep spindle induction.
Neurobit also provides a client-server based automatic real-time sleep scoring algorithm (using deep learning). They claim that their algorithm achieves human expert scorer accuracy. They've also published their research in a very respectable SLEEP journal: https://academic.oup.com/sleep/article/41/5/zsy041/4954046
