Ida Tin

CEO & Co-founder

Ida Tin is the CEO and Co-Founder of female health app Clue, the free-to-download, free-to-use period tracking app, designed to help women around the world track their periods and better understand their bodies. To date, Clue has more than 11 million active users worldwide and, in 2016, was named the most accurate free period tracking app by the Obstetrics & Gynecology, journal

Ida founded Clue in 2012, as she felt that reproductive health is an incredibly foundational and central part of our lives, but there’s a real lack of clarity for women over this generally. That starts the moment a woman has her first period, and begins to manage that part of her life, and continues as she chooses whether or not she wants to use birth control and, if so, which method to use. When Ida was about 30 she realised that her form of birth control wasn't working for her, but was unsure of alternative options. She thought it was insane that we were able to put a man on the moon, but we didn’t have a tool that would help us understand our body’s own patterns. This drove her to launch Clue - an app that could clue people in with personalised health data to give them awareness of the unique patterns in their bodies and their cycles. In March 2018, Clue launched a new website, becoming the first menstrual health hub, providing empathetic, reliable and scientifically accurate information regarding female health.

Ida is also credited with coining the term ‘femtech’ in the autumn of 2016. Femtech defines the group of technologies that are designed to support and advance women’s healthcare and include everything from period and fertility tracking apps, reproductive system health care, women’s sexual wellness products, pregnancy and nursing care, period care goods and at-home fertility monitoring devices.

By defining these products, Ida felt it legitimised the market, paving the way for dedicated femtech events and for VC’s to invest in Femtech portfolios. In March 2018, Frost & Sullivan released new data, predicting that the femtech market would be worth $50 billion by 2025.

Born in Copenhagen, Denmark, Ida graduated from the Danish alternative business school, Kaospilot. Prior to founding Clue, Ida ran a motorcycle tour company based in Denmark, touring locations like Vietnam, the United States, Cuba, Chile and Mongolia. She later published what became a best-selling novel, Direktøs, describing her experience.
