We set out to improve lives. One night at a time.


It all started when the 2 chronic insomniac founders and engineers Fares Siddiqui and Michal Maslik came together to fix sleep using hardware + software + artificial intelligence. We’re on a mission to help people say goodbye to sleeping pills, fall asleep naturally, and stay asleep longer.


We teamed up with world renowned sleep experts.
