## Summary

US YC W23 digital CBT-I sleep therapy at $60/month with 50% better results than sleeping pills; $6.5M total ($6M Initialized/YC/Goodwater seed Feb 2024) treating chronic insomnia psychologically competing with Sleepio.

## Company Overview

Stellar Sleep is a United States-based digital sleep therapy platform — backed by Y Combinator (W23) with $6.5 million in total funding including a $6 million seed in February 2024 led by Initialized Capital with Y Combinator, Lombardstreet Ventures, Switch Ventures, Moonfire Ventures, Scrum Ventures, 8vdx, and Goodwater Capital — providing chronic insomnia sufferers with a $60/month mobile app that delivers CBT-I (cognitive behavioral therapy for insomnia), acceptance and commitment therapy, and motivational interviewing through a structured program clinically validated to be 50% more effective than sleeping pills for long-term insomnia resolution. Founded in 2023, Stellar Sleep treats the root psychological and behavioral causes of insomnia rather than masking symptoms with pharmaceutical or supplement approaches.

Stellar Sleep's psychology-based insomnia treatment addresses the limitations of current sleep interventions: sleeping pills (benzodiazepines, non-benzodiazepines like Ambien) address insomnia symptoms temporarily but cause dependency, rebound insomnia when discontinued, and do not fix the hyperarousal and sleep anxiety patterns that sustain chronic insomnia. CBT-I (the gold standard for chronic insomnia per the American Academy of Sleep Medicine) achieves 70-80% remission rates with durable outcomes — but requires 6-8 sessions with a trained sleep therapist, which costs $1,000-$2,000 and has months-long waitlists. Stellar Sleep's digital CBT-I delivery (structured modules addressing sleep restriction therapy, stimulus control, cognitive restructuring of sleep beliefs, and relaxation techniques, delivered through the app at $60/month) makes the most effective insomnia treatment accessible at consumer scale — with 500-user clinical assessment validating the program's effectiveness.

In 2025, Stellar Sleep competes in the digital sleep therapy, insomnia treatment, and behavioral sleep medicine market with Sleepio (digital CBT-I, acquired by Big Health, $75M raised), Somryst (prescription digital therapeutic for insomnia, FDA-cleared, Pear Therapeutics), and Headspace (mindfulness and sleep, merged with Ginger) for chronic insomnia sufferer digital CBT-I access platform adoption. Initialized Capital's seed leadership reflects digital health and consumer subscription investment conviction. Y Combinator W23 backing connects Stellar Sleep with the digital therapeutics and mental health investor community. The 50% superior efficacy to sleeping pills metric positions Stellar Sleep as a clinical intervention rather than a wellness app. The 2025 strategy focuses on the employer benefit channel (chronic insomnia costs employers through absenteeism and reduced productivity), building the insurer reimbursement pathway for digital CBT-I as a covered preventive health benefit, and expanding the clinical validation dataset for health system partnership.
