Supermoon Capital

Supermoon Capital is a venture capital firm founded in 2021 and headquartered in San Francisco, California. It is widely recognized as the world's first VC fund exclusively focused on what it calls the "Night Market" — the sleep economy and circadian rhythm science. The firm was co-founded by Pat Connolly, Michael Masterson, and Grayson Judge, and launched with a $36 million debut fund. Beyond investing, Supermoon actively publishes market research on the sleep industry through a dedicated research platform and Substack, covering topics such as sleep interventions, diagnostics, dream technology, and the broader commercialization of circadian science. The firm also maintains a Sleep Science Collective — a network of academic and industry experts who inform deal sourcing and investment decisions. Its portfolio spans consumer, healthcare, and enterprise categories within sleep, including Endel (AI-powered soundscapes), EnsoData (AI sleep disorder diagnostics), Big Health (prescription digital therapeutics for insomnia), Mosanna Therapeutics (nasal spray for sleep apnea), Arcascope (circadian-based drug discovery), and Loftie (bedroom accessories), among others.
