What You'll Learn

Effectiveness of the Stellar Sleep app
The effectiveness of the Stellar Sleep app varies from user to user. While some users have praised the app for its ability to help them fall asleep faster and stay asleep longer, others have expressed disappointment with its effectiveness and cost.
Stellar Sleep is an award-winning mobile app for insomnia that was developed in collaboration with sleep psychologists, therapists, and researchers at Harvard Innovation Labs. The app uses cognitive behavioural therapy (CBT) techniques to help users develop healthier mental habits and manage anxiety, which is often a root cause of insomnia.
Some users have reported that the app has been a "game-changer" for their insomnia, helping them increase their sleep duration from 3-6 hours per night to 7-8 hours consistently within a few weeks. They attribute this improvement to the app's ability to identify deep-seated reasons for their sleep issues and provide a methodical plan to tackle them. One user highlighted the convenience of having various tools in one place, such as psych videos, sleep tracking, and thought and habit tracking.
However, other users have had different experiences. One user found the app ineffective for their specific issue of waking up in the middle of the night and struggling to fall back asleep. They also criticised the high cost of the subscription and the lack of transparency about the sleep restriction therapy approach. Another user mentioned that while the app helped make their sleep more consistent, their average number of hours slept remained unchanged even after a month of use.
The app requires an access code and offers a "free one-week trial" that requires payment. The cost of the program has been criticised as being too high, especially when compared to the level of improvement experienced by some users.
Overall, the effectiveness of the Stellar Sleep app seems to depend on individual factors and the specific sleep issues being addressed. While some users have experienced significant improvements, others have found the app ineffective or disappointing. It is important to note that addressing insomnia often requires a comprehensive approach that may include various factors beyond the scope of a single app.

Stellar Sleep app's founding and funding
Stellar Sleep is a mobile app that helps people with chronic insomnia get better sleep using psychology. The app was founded by George Wang and Edrei Chua, two chronic insomnia sufferers who grew frustrated with the lack of resources available to address their condition. They were told it would take six months to a year on a waitlist to be seen by a sleep clinician, so they took matters into their own hands and learned about sleep therapy, a psychology-based methodology that addresses the root causes of insomnia.
The Stellar Sleep app uses cognitive behavioral therapy techniques to help users develop healthier mental habits and manage their anxiety. The app combines several techniques, including acceptance and commitment therapy and motivational interviewing, to help users re-learn how to sleep well. The program is customizable and interactive, guiding users daily to improve their sleep. The app subscription is $60 a month, and users can connect their wearables.
Stellar Sleep was founded in 2021 as a venture at Harvard Innovation Labs and is headquartered in Walnut, CA. The company raised $6 million in seed funding from top investors, including Initialized Capital, Y Combinator, Allston Venture Fund, Capital F, and Goodwater Capital. The founders plan to use the funding to increase the amount of content and curriculum offered on the app and to expand their clinician partnerships to provide additional personalization of the user experience.
Since its launch in 2022, the app has helped tens of thousands of people improve their sleep. The company has strong clinical data showing best-in-class efficacy, and an ongoing clinical study with Harvard Medical School / Brigham & Women’s Hospital sponsored by the US Department of Commerce. The app reached $1 million in ARR within just 9 months, demonstrating the high demand for effective solutions for chronic insomnia.
