Vanessa de Waal

Product, People & Community (CEO)

Vanessa's passion for wellness had been no secret since she was 13. In spite of her healthy habits and passion for things like yoga and green smoothies, at 22 she was faced with a medical issue that had no cure. So she decided to immerse herself in a year's worth women's health research, supported by her mother, an M.D. She read everything she could on PubMed, ran experiments, and tried every health app out there. After two years she emerged with thriving health again determined to share her vision on how to make this process a lot easier for everyone else. Vanessa has committed her life to making the data science holistic wellness needs acessible. Her empathy for the user experience and their non-linear journeys drives her every day.
