What Stardust does
Stardust is a New York-based women's health technology company founded in 2020 that operates a mobile application focused on cycle tracking, fertility monitoring, pregnancy care, postpartum recovery, and menopause support. The company's product targets female consumers seeking enhanced reproductive health insights, with stated positioning that integrates science, ancient wisdom, astronomy, and AI. It serves a horizontally segmented audience of women across the reproductive lifecycle rather than concentrating on a single use case.
The core technology is a mobile app that bidirectionally syncs with Oura Ring wearable devices, layering Stardust's domain-specific reproductive health algorithms on top of Oura's continuous biometric streams (temperature trends, sleep patterns, activity levels, heart rate). This integration architecture is the company's primary technical differentiator: it delivers layered cycle, fertility, ovulation, postpartum, and menopause insights without Stardust having to build its own hardware or biometric collection pipeline. The app is distributed primarily through Oura's curated women's health partner ecosystem alongside Clue, Flo, Natural Cycles, Migraine Buddy, Peanut, Mira, Maven Clinic, and Carrot Fertility.
Stardust operates a subscription-based mobile application revenue model distributed through app stores and partner integrations. The company is privately held, has 1–10 employees, and has raised approximately $5.7 million across two disclosed rounds: a $2.2 million round in September 2022 led by Betaworks and Precursor Ventures (with Homebrew and Spacecadet Ventures), and a $3.5 million round in December 2023 led by NFX. Founder and CEO Rachel Moranis leads the organization. Pricing tiers, paying user counts, and revenue figures are not publicly disclosed, and the ownership and cap table remain unspecified in the source material.
