This latest funding round is led by existing investors, Balderton Capital and Union Square Ventures. For the first time in our history, we are also extending an invite to our user community to become investors via Crowdcube. This move brings our most important stakeholders, our community, even closer to the product development process while also giving you the opportunity to share in the Clue’s future success. 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.

Quote from Carrie

11 million people in 190 countries already rely on their Clue app every month, to better understand their own menstrual cycle patterns and learn about their reproductive health. While basic period tracking features are available for free, the premium subscription called “Clue Plus” offers subscribers additional evidence-based features and advanced insights. Subscribers also have access to modes like Clue Conceive, a CE-marked Clue feature to accompany users on their conception journey. The new mode has grown by over 50% in the last three months, now accounting for 12% of paying Clue Plus users.  

Ready for radical change

To meet the growing demand for non-hormonal contraceptive options, and with the goal of radically improving reproductive choice globally, at Clue we are focusing on scaling our digital female health and family planning tools. We will also expand our product portfolio to include underserved life stages, including menopause, to become a true companion app for life—from first period to last.

Core to our mission, Clue will also continue research efforts to close the gender data gap. Since launching ten years ago, our community has tracked over 530 million cycles and contributed to groundbreaking research with carefully selected research partners at institutions like Stanford and Oxford. A dataset of over 13B de-identified data points supports studies like investigating how the COVID-19 infection and vaccines would impact the menstrual cycle (to be published in the coming months). Insights from these studies are published for the benefit of Clue’s community, and everyone with a cycle.
