Muun Health is building a wearable patch that measures female sex hormones multiple times per day and streams real-time data to a mobile app to provide insights into ovulation and reproductive health. The device is presented as an alternative to urine strips and blood tests and is designed to deliver actionable data to users and clinicians. The company is developing a Smart Patch Platform and is focused on advancing a bioselective sensor layer to measure hormones from interstitial fluid. Muun received a €700K grant from Enterprise Estonia to fund that sensor development as part of a €1M project, and previously raised €545K in a pre-seed round in late 2025 from Greiner Innoventures and The Better Fund Community Business Angels. Founded in 2023 by Kerli Luks, Muun sits among a growing group of companies pursuing continuous hormone monitoring.
