Built for insomniacs, by insomniacs

We were insomniacs, tired of waiting for solutions that came too late. Stellar Sleep was born from that frustration.

We worked with sleep experts, converting our shared experiences into a digital solution. In 2021, we started as a venture at Harvard Innovation Labs to make our solution available to the world. Today we operate the largest network of insomnia clinicians in the US.*
