LunaJoy Health logo

LunaJoy Health

AI-powered scalable infrastructure + mental health services, starting…

LunaJoy is building the AI-powered care platform for precision mental health—starting with women. We integrate intelligent automation with specialized clinical services to deliver scalable, life-stage-specific care—from adolescence to pregnancy, postpartum, infertility, miscarriage, perimenopause, and aging. By embedding AI agents into care navigation, triage, and decision support, we reduce costs, accelerate outcomes, and personalize treatment at scale. Our hybrid care model blends targeted psychotherapy, psychiatric medication management, genetic testing, coaching, and holistic wellness—delivered by a curated workforce of women’s mental health specialists. Through continuous feedback loops, AI segmentation, and predictive insights, LunaJoy is built to scale. We’re expanding our in-network footprint to make this care accessible across commercial and Medicaid populations—closing equity gaps for women of color, LGBTQ+ individuals, and those most at risk. Women are twice as likely to experience mental health conditions, and 3x more likely to endure trauma. Yet the system is still built for the “average” patient—ignoring the biological, emotional, and social complexity of women’s lives. LunaJoy is rearchitecting that system with AI at its core—because when we invest in women’s mental health, entire communities thrive.
