MamaWell, founded in 2022, has built a digital health platform that supports women during pregnancy through personalized, evidence-based care. Using wearable devices, the service collects vital data such as heart rate and activity levels and blends it with 24/7 chat and online consultations from a network of personal midwives. The B2B-focused model has been adopted by more than 140 corporations, health-insurance associations and municipalities across Japan, including over 100 companies seeking to help employees stay in the workforce through pregnancy. By filling the gap between conventional medical care and workplace accommodations, the service is positioning itself as new social infrastructure. The company plans to expand corporate roll-outs, deepen alliances with local governments and hospitals, and grow its midwife network. Proceeds from the latest round will also strengthen product development so the platform can deliver seamless support from pregnancy through postpartum.
