Stellar Sleep (Y Combinator S23, backed by Initialized Capital) is a mobile app that helps people with chronic insomnia sleep better using psychology rather than medication. Its personalized program is based on CBT-I (Cognitive Behavioral Therapy for Insomnia), the first-line treatment recommended by sleep experts, delivered through iOS and Android apps published by Merlin Collective, LLC. Started at Harvard Innovation Labs in 2021, Stellar Sleep also offers clinician and employer programs, with clinical-system integrations arranged by its team. It is a consumer digital-health product with no public developer API, SDK, or MCP surface.
