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.*
Solve your sleep problems at the root
Insomnia is often a symptom of deeper challenges like anxiety, stress, or other things going on in your life. That’s why things like cutting coffee, and meditation aren’t enough.

Actual Stellar Sleep customer reviews
Really, actually works
I found Stellar Sleep at a point in my life where I hadn’t slept for weeks. I mean that literally. I track my sleep and I had gone for at least 3 weeks where Fitbit told me I literally had slept 0 minutes and 0 hours...
The first week...I didn’t think much was changing. More money down the drain. But then the second week, by some miracle I actually slept. I slept for 2 nights. My Fitbit counter was finally no longer at 0. Third week I slept for 5 nights. By the fourth week, I actually slept every single night.

Stellar Sleep has truly been a game-changer for my insomnia!
It does take some time to get going, but the app's cognitive behavioral therapy techniques have helped me develop healthier mental habits and manage my anxiety at night.
I literally went from 6 hours being a "good" night to regular 7 to 8 hours nights.

I’m a believer!
Stellar sleep has quietly changed my life. I like the emphasis on building skills that I can use to tackle my specific sleep issues vs other apps I’ve tried which try to just calm you down with generic seeming meditation.
I’ve found that a lot of my sleep problems are made worse by my anxiety, and Stellar sleep has helped me recognize that and handle it in a way where it no longer affects my sleep. More importantly the app has helped me believe that I can sleep like a normal person again.

Great app
Great app, because at the start of the 5 or so week program I slept horribly bad and have been, for many years. And now with a new less dramatic perspective on the hows and whys of that being the case, I sleep through the night. Problem solved. If you don't want to use an app such as this one (though I haven't seen one that is based on the same idea) you can easily seek out a sleep therapist instead, and I'm sure the therapy will be similar to this in general methodology:)

I'm impressed
I’m impressed by the usefulness of the app so far. I was skeptical when I first signed up because I’ve tried many other apps that claim they will help you improve your sleep. But this is the only one that works for me so far. I used to sleep only 3 - 5 hours a night, I’m 3 weeks into the program now and have been able to sleep 7+ hours consistently.

I’m finding it highly effective
I started suffering from insomnia after a major surgery, and my doctor recommended psychology to help with my sleep. I don’t have time to see anyone in person so this app has been a godsend. The program has been easy to follow so far and very effective in helping me get my sleep back to normal.
