Machine learning is allowing computers to compose classical music, drive cars, increase data security, predict the future—and now figure out the natural cycles of women’s bodies. Using equal parts science and technology, period-tracking app Clue connects five million women around the world to themselves and each other—with personal analytics, educational material, and immensely thoughtful design. Though the Berlin-based app often takes the role of educator, Clue founder Ida Tin stays in constant pursuit of knowledge. Between expanding her business and raising her children, she delves into the world of Femtech, learning from and connecting with innovators in the emerging sphere to provide her users with the most accurate and technologically advanced insights. Fresh from a $20 million round of funding, Ida Tin took She’s Mercedes for a short trip to Tempelhofer Feld to share the strategies and motivation techniques behind her revolutionary start-up.
