Berlin-based period tracker app bags €7m investment ahead of launching community funding round

The female-founded period tracker app Clue has secured a €7m funding round to bridge the gender data gap. 

The funds will be used to scale Clue’s digital family planning offering, expand the product portfolio, and continue research into women’s reproductive health.

Clue, a Berlin-based period and cycle tracking app, was founded in 2012 by Danish female entrepreneur, Ida Tin. The app calculates and predicts users’ periods and PMS based on users’ data, calculating fertility windows based on global averages.

More than 10 million people in 190 countries rely on the app every month to better understand their own menstrual cycle patterns and learn about their reproductive health.

Sine the app’s launch, users have tracked over 530 million cycles and contributed to “groundbreaking” research, the company says.

A dataset of over 13B de-identified data points supports studies such as investigating how the COVID-19 infection and vaccines would impact the menstrual cycle.

“So many of us still end up hacking our own solutions to health needs. Despite making up half the world’s population, the most common female health conditions still go unrecognised, under-researched, and underserved,” said Audrey Tsang, co-CEO of Clue.

“We constantly hear from our community that they feel their experiences are unheard or dismissed – except in Clue.

“We created Clue because health empowerment starts with better understanding your body. Having the language, and data, to describe your experience and advocate for yourself has a profound impact.

“The fact that it still takes an average of seven years to get an endometriosis diagnosis is just one example of how much work there still is to do in this space.”

“We believe Clue is uniquely positioned to lead the change that’s needed, at scale, by leveraging our technology, deep community insights, and research to create empathetic, effective, and accessible solutions for the most frequently experienced challenges in female health.”

Its latest funding round, hoped to drive more research into women’s menstrual health, has been led by existing investors, Balderton Capital and Union Square Ventures.

However, in a move to bring its community closer to the product development process, the company has also extended an invite to its user community to become investors via Crowdcube.

Community investors will be able to participate in and influence the app’s development through feature polls, testing, and forums directly with the Clue team.

Carrie Walter, co-CEO of Clue, said: “Clue has always been supported by some of the world’s leading investors. Today, we’re taking that one step further, by being the first menstrual and reproductive health app to invite our community to invest and become co-owners.

“After all, Clue only exists to serve this community, and because of their trust. So we see this as an exciting chance to connect with them in another way, benefitting from the depth of their engagement and diverse perspectives.

“We feel it closes an important circle to give Clue users the opportunity to participate in our success, also as investors.”
