Lina Wüller

Lina co-founded the female health startup Ovy with her younger sister Eva two years ago. Their mission is to empower women around the globe to control their reproductive health by offering smart technology. The two sisters built a Bluetooth fertility thermometer and connected the device with the Ovy app to help women calculate their fertile window, the day of ovulation and their next period. On top of that they launched various other women care products which are relevant for each cycle phase, e.g. organic tampons. The two sisters raised funding from different investors such as the hardware producer Beurer or the publishing group Klambt. Their company is based in Hamburg.
